郑幼林：雕鉴估皆精的三绝专家

郑幼林：雕鉴估皆精的三绝专家

　　新当选中国轻工业联合会、中国工艺美术学会联合评选的中国石雕艺术大师,长达55分钟的个人艺术专访在中央电视台国际频道播出,在海峡文化产权交易所[微博]主办的文儒讲坛开讲“寿山石雕刻与国学”,增补为第十二届福州市政协委员……寿山石雕艺术家郑幼林2012年可谓收获颇丰,实际上这位刚过不惑之年的雕刻家不仅是名闻国内外的寿山石雕大师,还是福州寿山石鉴定中心、福州雕刻工艺品总厂、福建省民间艺术馆[微博]、福建省寿山石文化艺术研究会等几乎全部寿山石鉴定机构的权威鉴定专家,以及福建几家寿山石拍卖机构的权威评估专家,更以其雕(刻)鉴(定)估(价)皆精的能力成为寿山石雕界投资收藏的首席顾问之一.

　　闻名国内外的田黄专业户

　　田黄石因石材稀少,自古就有“一两田黄三两金”之称,近年更是频频出现每克几万元甚至十几万元的天价成交记录.田黄石的珍贵导致普通雕刻家不敢轻易下刀,恐怕浪费石材而损耗田黄石雕的价值,而这种谨慎保守的创作态度在束缚雕刻家创作思路的同时,更是导致艺术性强的当代田黄石雕精品随着田黄石雕价格的走高却日趋少见.

　　作为寿山石雕界中青年的中流砥柱,上世纪60年代末出生于福州鼓山的郑幼林却以巧夺天工的构思和娴熟的雕刻技艺,创作出数量颇多的当代田黄石雕精品.郑幼林在熟练掌握各种寿山石雕刻技艺的基础上,运用圆雕与高浮雕相结合、写意与写实相结合的技法,大胆采用夸张艺术创作田黄石雕,不但整体构图符合当代审美标准,而且细节也均刻画得惟妙惟肖、形神兼备.与此同时,虽然他大胆以极费石材的圆雕技法创作田黄石雕作品,却也总能设计出最节省原材料的作品,这让其在业界一炮打响；加上其不仅精通各种雕刻技法,而且将传统美学、西方美术理论、中西方哲学融入寿山石雕之中,创作出了系列技艺精湛、艺术品位高雅的寿山石雕佳作.由于郑幼林创作的童子、弥勒等题材作品皆栩栩如生、风格独特,显示了其精湛的雕刻技艺和独有的艺术韵味,深得高端藏家青睐,故请其加工田黄者络绎不绝,甚至有人为请其雕刻,宁愿排队等数年也不肯让其他人雕刻,而郑幼林也因雕刻田黄作品数量较多而被石雕界和收藏界称为“田黄专业户”.

　　2012年,刚过不惑之年的郑幼林不仅当选中国轻工业联合会、中国工艺美术学会联合评选的中国石雕艺术大师,中央电视台国际频道更是制作并播出其长达55分钟的个人艺术专访,这也是中央电视台首次播出如此长时间的寿山石雕艺术家专访,这说明了其雕刻技艺已经得到了国内外业界的广泛认可和好评.而此前,其作品不仅先后入藏中国寿山石馆、福建博物馆、福建工艺珍品馆,而且其作品还于2009年入藏北京故宫[微博]博物院,成为作品入藏故宫博物院的首批当代石雕艺术家之一.

　　各大鉴定拍卖机构的权威专家

　　天遗瑰宝寿山石以“剖之斑斓具五彩,他山之石皆卑凡”的美誉冠绝天下.而与这美誉相伴的,则是数以百计的寿山石种,除了田黄石、芙蓉石、荔枝洞石等玩石者皆知的石种,还有善伯洞石、都成坑石、汶洋石等常见石种,更有尼姑娄、金狮峰、寺坪石等数量稀少之石种,其中如高山石等更分为四股四高山石、水洞高山石、桃花高山石等进一步细分的石种,虽然目前出版的专业寿山石书籍未能全部统一,但每种分法的石种也均在200种上下.因不同的石种从外形、色泽至肌理,都有其独特之处；再加上当前寿山石行情一路走高,造假技术也层出不穷,石种鉴别更加复杂难辨,这不仅让初入行之藏家无所适从,就是浸淫已久的资深藏家和从业数十年的雕刻家也常常“打眼”.

　　石种多且难区别,同等质地的作品因石种不同,价格则高低不等,甚至相差几倍乃至数十倍.作为决定鉴定机构水平高低和拍卖机构盈亏关键之所在的寿山石鉴定和评估专家,也就顺理成章成为各大鉴定机构和拍卖机构争相招揽的抢手人物.“田黄专业户”郑幼林不仅是名闻国内外的寿山石雕大师,而且还凭借数十年的雕刻经验和长期的寿山石学术研究、收藏经验、与众不同的眼光,成为寿山石雕界各大鉴定机构和拍卖机构的权威专家.目前寿山石鉴定权威机构主要有福州寿山石鉴定中心、福州雕刻工艺品总厂、福建省民间艺术馆、福建寿山石文化艺术研究会、福建省宝玉石协会等几家,郑幼林则是寿山石雕界惟一一个在这几家鉴定机构全部担任鉴定师的权威专家.

　　除了能准确鉴定石种之外,郑幼林还是海峡文化产权交易所、福州市寿山石文化艺术品交易所、福州雕刻工艺品总厂等举办寿山石拍卖机构的权威评估专家,他根据自己的经验和对市场行情的准确把握,总是能对送拍品给出最贴近市场价值的评估,给拍卖行提供相对准确的依据,从而使拍卖机构做出是否可以收件上拍的判断.

　　寿山石雕收藏投资的首席顾问

　　当前艺术品市场的巨大升值潜力已被大量爱好收藏的企业家所看好,也有数量颇多的巨额资金流入艺术品市场,但是艺术品应该如何收藏投资却一直是争论不休的难题,更是困扰着喜欢寿山石雕的各类人群.

　　作为既懂雕刻又精通鉴定和评估的权威专家,郑幼林近年来成为不少机构和个人的收藏投资顾问,其个人的投资收藏事例更是成为业界流传的经典范例.如其2009年辗转从别人手中购买的中国雕塑大师王则坚的作品《海的女儿》和中国工艺美术大师叶子贤的作品《六子戏弥》,当时是花了别人眼中的天价,结果却不到一年就翻了数倍.在石雕界,因郑幼林建议购买的寿山石雕短短时间内翻倍的例子可谓数不胜数,数倍升值的案例也屡屡出现,一些大型寿山石交易机构外出收购货品更是经常要其全程陪同.

　　针对喜爱寿山石雕的藏家,郑幼林提醒想介入寿山石领域的新人要注意寿山石雕专业知识的积累,要多看多问多把玩.“玩”石头首先是喜欢；其次是玩品味,要多玩品质典雅、工艺简炼淳朴的作品；再者是量力而行.对于热衷参与拍卖会的买家,在参加拍卖会之前需要对自己的心仪之物多做功课,听听专家对作品整体的评价,在了解拍品石种优劣、石质高低、有否瑕疵、作者是否名家等,以及作品创意和造型的好坏和文化品位高低等综合因素后,建立最基本的价值判断,并确保拍卖现场不受心理和环境的影响,方能从容应对瞬息万变的拍卖市场.

　　郑幼林经典语录

　　■寿山石的经济价值受多方面因素影响,包括整体的经济环境、作品的材质雕工、专业团队运营水平等.寿山石的人文价值是通过艺术家融合古今中外知识,根据石材特点,化腐朽为神奇.

　　■艺术品投资首先要准确了解本土的艺术品市场,要关注当地最受藏家和各大金融机构青睐、流通最广、在全国享有较高知名度的艺术品种,并对这些当地最有特色的艺术品类进行充分调研的基础上进行投资,方能获得最大收益.

天津贵金属及珠宝玉石饰品标识标准将实施

天津贵金属及珠宝玉石饰品标识标准将实施

　　人民网[微博]·天津视窗1月31日电:临近春节,珠宝首饰也将迎来销售高峰.为维护珠宝首饰市场经济秩序,天津市质监局公布了《贵金属与珠宝玉石饰品标识》地方标准,对贵金属与珠宝玉石饰品的标识、销售票据内容和要求等作出明确规定,标准将于今年2月15日起实施.届时,消费者买珠宝将有依据,挑选珠宝不再眼花缭乱,可以凭借标签标识进行辨别.

　　标识标签待规范

　　目前,珠宝行业中标识混乱现象普遍存在, 有的商家不标注珠宝玉石名称,还有的用“产品寓意”代替珠宝饰品名称.有的仅标注行业内不规范的商业俗称,翡翠B货、24K黄金等等这些出现在首饰标签上,人们耳熟能详的名称,其实都是一些不规范的商业俗称.有的不法零售商甚至混淆、杜撰珠宝玉石和贵金属名称,“沙金”、“钯铂金”、“锻压金”等不规范标签名称已成为部分珠宝店误导消费者的伎俩.一些商家以次充好,以假乱真,如有的以合成钻石充当天然钻石,按新出台的《标准》要求,人工合成钻石必须注明“合成”二字.

　　买珠宝将有依据

　　按照《标准》,饰品的交付应包括饰品标识和销售票据.其中,饰品标识由印记、标签和其他标识物等组成.

　　饰品标识的内容应简明、准确,易于阅读和理解,并包括必要的中文警示说明.贵金属饰品印记应清晰地标注:厂家代号(已备案的厂家代号或注册商标等)以及贵金属材料及纯度；钻石镶嵌饰品的印记应清晰地标注:主钻石的质量(主钻石质量大于0.10ct时),配镶石为钻石的,可单独标注出配镶钻石的总质量.

　　印记内容要求完整、清晰、准确,打印在易于观察的位置；当贵金属饰品主体和配件的纯度不一致时,其印记应分别标注,当饰品由两个单体或两个以上单体组成时,其印记应分别标注等等.

　　标签标注内容至少应包括饰品名称、产品标准编号和生产企业(或销售商)的名称；以质量计量单位作为计价单位进行销售的应标注质量；以饰品整体进行计价销售的应标注销售价格.饰品名称由材质名称和品种名称组成.例如:翡翠手镯、铂(Pt)950蓝宝石戒指,其中,翡翠、铂(Pt)、蓝宝石为材质名称,手镯、戒指为品种名称.此外,钻石饰品应逐件附带有钻石分级证书或鉴定证书.

　　需注意的是,群镶珠宝玉石的饰品,命名中应包含价值最高、体积最大或数量最多的珠宝玉石的名称,其他珠宝玉石应该在标签的其他位置或其他标识物中明确标注.

　　销售票据应该写点啥？

　　与国内其他城市出台的类似《标准》相比,本市出台的《标准》一大亮点是,对票据提出了明确要求.

　　饰品销售票据上填写出的内容应至少包括经营企业名称、饰品名称、质量或规格、价格以及相关法律法规中规定的内容.经营企业的名称应为依法登记注册的企业名称.饰品名称由材质名称和品种名称组成,应与标签上所示一致.其中对于钻石饰品,裸钻或镶嵌钻石主石大于0.10ct的钻石饰品,应在销售票据上注明钻石质量,以克拉(ct)为单位；贵金属饰品,以质量计量单位作为计价单位进行销售的饰品,应注明其质量,以克(g)为单位.应与标签上所示一致.此外还包括价格及要求等.(记者 郑东红 通讯员 穆巍)

玉雕师巧手雕刻翡翠罂粟劝人戒毒

玉雕师巧手雕刻翡翠罂粟劝人戒毒

钱贵根在仔细雕琢玉器.

　　广佛都市网讯 佛山日报记者刘先进报道:“鉴玉尚质,执玉尚谨,用玉尚慎.”小小一块玉石,在他眼中,不仅是一件饰品,还是一件富含哲理的艺术品:能传递正能量,藏金玉良言,可劝人远离毒品,可宣扬环保.

　　他是钱贵根,首创“三水工”,被称为“中华玉雕艺术大师”.

　　自创“三水工”,人称“花件王”

　　钱贵根是三水人,28岁时前往香港谋生,并在一家玉器小作坊中学习玉器制作.虽然没有系统学过玉雕技术,他却自学成才.1979年,钱贵根回到三水,办起三水当时第一间外商企业,并在上世纪90年代创立品牌“碧玉丰珠宝”.

　　多年磨练,让钱贵根吸取了传统工艺的精髓及各种雕刻技艺之长,不断创出新花式,形成手法独特、工艺精湛的“三水工”.“‘三水工’外形大小厚薄适中、外形长宽比例符合黄金比.雕工继承传统砣工的旋转流畅、气势奔放,并结合象牙工的精雕细琢.”钱贵根说,“三水工”花件以细致创新的工艺著称,在传统设计基础上大胆采用不同颜色的翡翠原料,以流畅的线条为基调,糅合文化元素于花件当中,流露高雅华丽、清雅自然的气质.

　　由于工艺独特,钱贵根被誉为“花件王”.三水玉雕已成功申请为三水区第四批区级非物质文化遗产项目.作为玉雕继承人,钱贵根在去年还被中华工商联合会授予“中华玉雕艺术大师”称号.

　　翡翠壁挂劝人戒毒

　　温润如玉的钱贵根,喜欢将对社会现象的思考注入玉雕中,“做玉雕不能向商业低头,要有自己的思考和意境,将正能量传递进去,关键不在雕刻,而在创意和想法.”

　　十几年前,有感于有人染上毒瘾不能自拔,钱贵根用翡翠创作了壁挂《罂粟》.在壁挂上,三株罂粟正妖艳的盛开,下方附了一首他写的诗《罂粟——美丽的陷阱》:一吸毒品终世穷,二脚踩入无底洞,三代受累全家苦,四处借钱债台重,五体发抖瘦如柴,六亲不认兽性凶……

　　壁挂问世后,获得全国玉雕“天工奖”.令人想不到的是,不少酒家、歌舞厅还找上门来购买.2002年,钱贵根将此作品捐赠给三水的禁毒部门,作为禁毒公益宣传专用纪念品.

　　钱贵根还雕过一片落叶,并题诗《根对叶的赞美》赞美老一辈革命人士的奉献精神:“你的抢先,不是为了地位,而是追求光明……你的离去,不是为了解脱,而是顾全大局；你的腐烂,不是为了歪念,而是落叶归根.”

　　玉雕作品宣扬环保

　　钱贵根很多作品都是利用废弃原料做成的.

　　他曾创造一件名为“2002年”的作品.钱贵根说,“2OO2年”既表示年份,又是氧气的化学式,两个标点符号和字母H很接近,组合起来是水的化学式HO2,氧气和水恰恰是人类生存的必要条件；“年”字为绿色,寓意大树；“年”字下方,围住了黄、白、黑、棕四色栏杆,寓意全球四色人种齐心保护环境.

　　尽管荣誉等身,但钱贵根仍孜孜不倦的推广玉雕文化.目前,其玉器文化展览已走遍全国.今日,他将在三水广场举行三水长寿翡翠文化展,“希望有更多人了解玉雕,喜欢上玉雕.”

珠宝店被撬门百万玉器被卷走

珠宝店被撬门百万玉器被卷走

　　广佛都市网讯 珠江商报记者杨安摄影报道:珠宝店大白天居然被人撬开大门卷走店内价值百万的玉器饰品？市民关先生昨日向本报反映,他在大良云良路康华楼工作的珠宝店内所有货品突然不见了,记者了解原是该店老板玩失踪,在其店内承租柜台的玉器商人为取回自己的货物故有此举,警方已介入调查.

　　“眼看就要过年了,老板却玩起了失踪.”昨日,关先生十分焦急地向记者诉说,他的老板在云良路康华楼开起了这家珠宝行,除请了一批员工加工首饰外,还将店内11个玻璃柜租给了玉器商人进行经营,生意一直不错.可在本月22日下午,关先生突然接到店老板电话,称有事跟他商量.“他说他出了点事,这两天不能呆在店里,让我帮他看一下店.”关先生说,在征得他同意后店老板将店钥匙给了他.“不知为何,后来老板的电话就一直打不通了.”

　　老板失踪的事爆出后,在珠宝店内租柜台卖玉器的商人虽然合同期未到,也提出撤走的要求.“我让他们先把货留下继续经营,其他事情等找到老板再作处理.”关先生说因为受了老板的嘱托,他不能擅作主张让玉器商人搬走店内货物,这批商人当时表示理解也答应了他的建议.可第二天他仍然联系不到店老板,害怕玉器主真的拿货走人,他店也没开就将店门给锁上,可在26日那天就发现店门被撬开,店内玉器主租的11个玻璃柜内的玉器全部不见了,他立即报了警.

　　根据警方初步调查,该珠宝店老板已经失踪几天,在店里租柜台卖玉器的商人想拿回玉器走人,但店里员工就说老板还没回来,不让他们搬货走,所以才有珠宝店大白天被撬门的事情发生.警方表示,这是一起经济纠纷案,警方正在进一步调查协调处理此事.

年底淘绝当品很划算：首饰玉器手表居多

年底淘绝当品很划算：首饰玉器手表居多

　　楚天金报讯 金报讯(记者彭鹏)一心想买条铂金项链的方女士,昨日中午特意到积玉桥一家典当行淘宝.她看中一款项链,重3.98克,每克仅售358元,她二话不说立马掏钱买单,“要知道铂金在商场一克500多元,这里便宜好多,买回去找个师傅重新改个款式就行了”.

　　岁末,典当行的“绝当品”开始增多,又到了捡便宜的好时机.所谓“绝当”,业内人士也叫“死当”.一般来说,过了当期5天,典当者没有赎回的物品就成了“绝当品”.记者近日走访发现,“绝当品”中贵金属首饰、钻石玉器、手表品类最多,其中贵金属首饰最受青睐,尤其是黄金饰品,占总销售的六成以上.“绝当品”价格均比市场价便宜,其中手表比市场价便宜一半,饰品黄金每克仅359元.

　　其他典当品,类别不一样,折扣也不相同.一般来说,钻石的评判标准略多,讲究净度、白度、光洁度,一般是市场价的六到七折；名表则是市场价的五折到六折；玉器在收取时按照市场批发价,然后加收一定的利润卖给消费者,但肯定比市场价便宜.

　　据悉,购买“绝当品”在北京、上海等发达城市较为普遍,武汉市民接受度相对较低.瑞恒典当行首席典当师潘建伦说,典当行在收当时,为了绝对控制放贷风险,会对当品进行严格把关.无论是名表、翡翠玉石珠宝首饰、数码产品都会经过仔细鉴定和价值评估所以,“绝当品”都是货真价实.珠宝首饰都可以后期进行加工改款式,只要价格合适,不妨当即买下.

　　市民如果有意愿购买“绝当品”,应该常到典当行看看,并与市场价进行比较,遇到合适的或者自己需要的再买.在购买时一定要求典当行提供物品的详细资料和单据.“绝当品”出门后,多数典当行不提供退换货服务.

Energy Micro to showcase cool customer apps at embedded world

Energy Micro to showcase cool customer apps at embedded world

The guys and gals at Energy Micro, who cheerfully describe themselves as "The energy friendly microcontroller and radio company," will showcase a number of customer applications for their EFM32 Gecko families of ARM-based microcontrollers (MCUs) at Embedded World 2013. These will demonstrate how energy efficient devices greatly extend battery life in real-world products.

On show will be products spanning various industry sectors for such diverse uses as dive watches, avalanche monitors, home automation controls, and utility meters. Velux, a company well-known for its roof windows and blinds, has selected the EFM32 Giant Gecko microcontroller for the touch screen interface in its award winning 'Velux Integra' series of electric window remote controls. PIEPS GmbH, a long-established Austrian company that is a leader in life-saving avalanche transceivers, has designed the EFM32 Cortex-M3 MCU into its top-of-the-range handheld avalanche monitor, the 'PIEPS VECTOR', for use by mountaineers and rescue services. Miitors, a developer of leading edge IP for water meter manufacturers, has created a new standard in smart meter designs using ultrasonic sensors and offering WMBus and NFC communication. With support from Energy Micro, Miitors has been able to achieve an ultra-low energy design that provides extreme long-life operation.

Low power applications like these utilize the EFM32's low-energy sensor interface (LESENSE) and peripheral reflex system (PRS) to provide autonomous monitoring of sensor inputs while the MCU remains in a sub-microamp Deep Sleep mode. In this way, the EFM32 Gecko devices enable customer designs to achieve the performance they need for responsive wake-on-touch control, routine data collection or wireless communication, in products where minimizing energy consumption and preserving battery life is vital.

Freescale attacks Cavium with security coprocessors

Freescale attacks Cavium with security coprocessors

SAN JOSE, Calif. – Freescale Semiconductor is rolling out a family of three security coprocessors, targeting a market dominated by rival Cavium Networks. Freesacale claims its C29x chips, ranging in price from $99 to nearly $200, will deliver 50 to 250 percent more operations per dollar than Cavium’s Nitrox 3.

Despite its plans to significantly undercut Nitrox 3 prices, Freescale and analysts watching the company say it should still reap comfortable margins. “We think [Cavium has] been getting crazy margins,” said Derek Phillips, a senior product manager at Freescale.

The C29x is optimized to handle 2048-bit RSA encryption, the level recommended currently for secure transactions by the National Institute of Standards and Technology. It also process Diffie Hellman, and Elliptical Curve Cryptography algorithms and bulk encryption at rates of 8 to 10 Gbits/second.

The high-end chip uses three processing engines to deliver 32,000 2,048-bit RSA transactions/second at 10W. Dual- and single-engine versions hit 18,000 and 8,000 transactions/s, respectively. That compares to a few hundred transactions/s for the embedded security blocks on current QorIQ SoCs, said Phillips.

The chips require no external memory for RSA operations. However, external memory is needed to support secure boot and tamper detection features.

The first devices will ship before April. They run on a x4 PCI Express Gen 2 bus.

The C29x promises “significantly lower costs at a time when network security has never been more important,” said Joseph Byrne, senior analyst with the Linley Group (Mountain View, Calif.). “The security coprocessor space is a potentially high-margin market for Freescale,” he said in a Freescale press statement.

Ultra low power controllers get new benchmark

Ultra low power controllers get new benchmark

SAN JOSE, Calif.--Ultra low power microcontrollers will get a new yard stick by this fall from the Embedded Microprocessor Benchmark Consortium. EMBC’s ULP benchmark will measure energy consumed running workloads for chips targeting portable medical devices, security systems, building automation, smart meters and other devices that aim to run for years on a single battery.

“When these devices are in real low power modes it is not just about their execution times but how well they use sleep modes, how often they have to wake up processors and how much energy they waste,” said EEMBC President Markus Levy. “We will simulate measurements over a year or even a decade,” he said.

Just how the benchmark will operate is still under discussion by a working group headed by Horst Diewald, chief architect of MSP430 microcontrollers at Texas Instruments. Other companies represented in the group include Analog Devices, ARM, Microchip, Renesas and STMicroelectronics.

Atmel, Energy Micro and Silicon Labs have joined EMBC also are members of the working group. Lockheed Martin is an observer on the effort and an EMBC board member.

“We would like to have more system companies participate at least as advisers,” said Levy. “Once we get our first phase out, we may get more participants from systems companies."

Membership to EMBC costs $75,000 for the first year. The ULP group hopes to have an alpha version of its benchmark out to members before April and a publicly available version in the fall.

　　据了解,进入新世纪,寿山石开始跻身拍卖市场,以多年来强劲的市场表现,在各收藏门类中的地位也逐步得以凸显.受国内艺术品市场整体态势的影响,2012年寿山石市场的行情表现也相应回落.不过,值得宽慰的是,从数据上看,与其他工艺美术门类相比,寿山石的表现则较为坚挺,个别品种甚至表现出逆势走强的格局,比如说田黄石.田黄石的优异表现已经引起整个艺术品收藏市场的关注.并有媒体将2012年的寿山石市场称之为“田黄年”,足以看出业界对这一版块的重视.寿山石越来越受到藏家的关注,已经成为艺术品市场关注的热点之一.

　　“虽然近几年寿山石的市场行情较为突出,然而相较书画等成熟门类,工艺美术在艺术创作、文化传承以及市场拓展方面上都还比较薄弱,因此非常需要专业研究机构的介入”,省民间艺术馆馆长夏浈介绍,这是省民间艺术馆转型的主要原因,“我们发布这份报告的目的,是期望通过大量的实地调研和数据分析,对过往市场表现忠实的记录和总结,还原真实的市场环境,每年发布这样一份报告回顾市场,也算是我们对这个行业做的一点微薄的贡献.”

　　据悉,福建省民间艺术馆于2011年开始着手调研、撰写寿山石拍卖市场调研报告,旨在从市场层面客观把握当前寿山石拍卖市场的发展现状,辨析寿山石行情发展特点和规律,分析寿山石在国内艺术品市场所处的地位,研究当前制约寿山石行业进一步发展的因素,为更好地促进寿山石市场持续健康发展提供决策依据.2012年初春,福建省民间艺术馆发布了首份报告——《2011年度寿山石市场分析报告》,同时这也是当代工艺美术领域第一个细分行业的市场分析报告.这本报告由人民日报出版社出版,报告发布之后反响热烈,获得业界及收藏家的广泛赞誉.

　　宏观分析微观指导

　　研究市场现状 研判市场走势

　　而据记者了解,《2012年度寿山石市场分析报告》目前也已经编写完毕,省民间艺术馆将于春节过后发布.报告内容包括经济环境影响下的艺术市场整体态势、寿山石拍卖行情走势、市场突出现象分析以及福州地区寿山石一级市场的调研分析等.在宏观、微观两个层面上对艺术品市场现状及其变化特点进行考察,并对市场未来做出科学判断.

　　相较2011年的首份“白皮书”,此次白皮书内容还增加了对福州寿山石一级市场的调研,并对2012年度寿山石拍卖市场热门艺术家的作品进行了数据整理和分析.这些内容的扩充使这份报告的视野更为全面.不仅从市场中的宏观数据着手分析上,还深入解读寿山石的区域发展情况,并从藏家审美转变及市场推广方面剖析寿山石市场环境.

　　一位寿山石资深藏家告诉记者,省民间艺术馆发布寿山石市场白皮书,将在很大程度上促使市场成熟理性,帮助藏家掌握市场规律.这份白皮书不仅能够让藏家了解寿山石行业发展现状,还可以为寿山石的投资者和收藏机构提供相关专业性的市场信息和学术层面上的帮助,白皮书是寿山石行业逐步完善走向成熟的一个标识.

　　专业的寿山石市场分析

　　促进市场的逐步成熟

　　报告中指出,伴随市场行情的变化,2012年寿山石拍卖市场呈现非常鲜明两极分化趋势、高价藏品保持强势、低价位藏品交投活跃而中端市场疲软的M型的市场结构已经确立.收藏群体在拍场中表现较为理性,出手相对谨慎.而拍卖机构为应对市场趋势纷纷调整经营策略,精简数量、提高品质成为普遍措施,成熟的拍卖机构关注收藏群体审美需求的同时更加追求精耕细作,向着专业化、学术化的发展方向不断进步.在经历了2011年艺术市场的火爆之后,2012年的市场趋势回落.这一态势既促使了各方从业人员开始调整经营策略,也留出空挡让人们对整个市场进行冷静的思考与重新认识,于是消除泡沫、回归理性成为今年市场中的价值主导.在此关头,如何重新梳理寿山石的市场脉络,客观理性地认识市场的周期性变化,发现市场中存在的问题以及寻求扭转的途径,成为整个行业的当务之急.

　　同时,2012年寿山石市场中所呈现出的诸多新现象,也为行业带来很多新的思考.比如成熟的拍卖机构在市场弱势环境中,如何以其专业化的运营来引导市场趋势,其结果是否体现了机构投资者对寿山石市场的预期？艺术家重要作品的市场表现是否意味着寿山石雕刻艺术的发展趋势？这些问题都将对未来寿山石市场产生深远影响.如何判断寿山石市场行情与趋势,如何看待寿山石市场格局和现状,以及如何促进行业提升自身在工艺美术领域中的地位,这份报告都将一一阐述.

　　“我们发布这份报告的目的,就是期望通过大量的实地调研和数据分析,对过往市场表现忠实的记录和总结,还原真实的市场环境,并尽量发现市场的盲点和误区.希望这份报告能够对业界有所启迪,并帮助收藏家和投资者完善自身投资策略,共同促进寿山石行业的健康发展.”省民间艺术馆馆长夏浈向记者介绍.

Ultra low power controllers get new benchmark

Ultra low power controllers get new benchmark

SAN JOSE, Calif.--Ultra low power microcontrollers will get a new yard stick by this fall from the Embedded Microprocessor Benchmark Consortium. EMBC’s ULP benchmark will measure energy consumed running workloads for chips targeting portable medical devices, security systems, building automation, smart meters and other devices that aim to run for years on a single battery.

“When these devices are in real low power modes it is not just about their execution times but how well they use sleep modes, how often they have to wake up processors and how much energy they waste,” said EEMBC President Markus Levy. “We will simulate measurements over a year or even a decade,” he said.

Just how the benchmark will operate is still under discussion by a working group headed by Horst Diewald, chief architect of MSP430 microcontrollers at Texas Instruments. Other companies represented in the group include Analog Devices, ARM, Microchip, Renesas and STMicroelectronics.

Atmel, Energy Micro and Silicon Labs have joined EMBC also are members of the working group. Lockheed Martin is an observer on the effort and an EMBC board member.

“We would like to have more system companies participate at least as advisers,” said Levy. “Once we get our first phase out, we may get more participants from systems companies."

Membership to EMBC costs $75,000 for the first year. The ULP group hopes to have an alpha version of its benchmark out to members before April and a publicly available version in the fall.

香奈儿1932年钻石珠宝展

香奈儿1932年钻石珠宝展

　　二战风暴来临前夕，1930年代的巴黎依旧是个金粉世界，华丽的夜，一如既往地展现了最后的璀璨和欢悦。其中一场优雅的社交聚会的请柬上仔细地写着：

　　“香奈儿[微博]的‘Bijouxde Diamants’钻石珠宝展，1932年11月7日至19日，在香奈儿女士宅邸举行，巴黎圣奥诺雷街29号。”

　　《L’Intransigeant》日报于1932年10月26日抢先发布了这条独家新闻：“11月7日，全球知名的服装设计师首次创作的高级珠宝设计系列，将揭开神秘面纱。这一次所发布的作品非常特别，不再是她过去经常为点缀服装所设计的服饰珠宝，而是铂金镶钻的高级珠宝系列。” 《L’Intransigeant》日报接着报道，这次香奈儿女士的高级珠宝设计，展现了两项新特色：首先，珠宝镶嵌设计得简洁轻盈，完全烘托出钻石之美。其次，珠宝设计得灵活曼妙，可以随着心情自由变化出多种佩戴方式，展现不同风姿。例如，星星主题的首饰，可以是一条闪耀在粉颈上的项链，亦或化身为一枚胸针，或置于手镯中央，成为视线焦点。

　　无论是高级珠宝还是高级定制服，香奈儿女士始终坚持一个信念：不能把女性禁锢在盔甲里，应当赋予她们行动的自由。“我希望我的珠宝，轻盈贴合，犹如缠绕于女子纤指上的丝带，”香奈儿女士在接受《L’Intransigeant》日报采访时说道，“我要以璀璨群星装点女性。星星！大大小小、闪耀夺目的星星。看看这些彗星，闪亮的星星栖于肩膀，闪烁的星尾绕过肩头，宛如一片星雨洒落胸前！”

　　她向《L’Illustration》周刊**的记者阿尔伯特·弗拉芒(Albert Flament)透露，她的灵感只是简单地来自巴黎的星空。她沿着香榭丽舍大道信步前行，街上闪烁着五光十色的广告，夜空繁星璀璨，一弯新月挂在天际。“为何要舍近求远？”就这么，启发了她无限创意。

　　香奈儿女士在表述对“Bijouxde Diamants”钻石珠宝系列充满诗意的设计理念时，当然是诚恳的，但也许，连她自己也没有意识到，她对于星星、月亮、马耳他十字架的钟爱可以回溯至孩提时代。对幼时的经历，她向来缄口不言，她以自己独特的方式，重塑而且美化了这段时光。1895年，香奈儿12岁时母亲辞世，父亲将她遗弃在科雷兹省的奥巴辛修道院。每天清晨，幼小的嘉柏丽尔和修道院的其他寄宿生一起，去教堂望弥撒。她们会经过一条长长的走廊，长廊地面的鹅卵石铺成弯月、星星、马耳他十字架等图案，这些充满宗教象征意味的图案就此深深地铭刻在她的记忆中。

　　1932年11月6日(周六)，展览正式揭幕前夕，本来这晚的预览仅对媒体开放，但名流们已等不及第二天正式开展，纷纷闻风而至。数十辆载着名媛贵妇的轿车排成长龙，停在圣奥诺雷街29号的门前(嘉柏丽尔。香奈儿租住在罗汉-蒙巴宗豪华酒店的底楼)。香奈儿的珠宝展，轰动了整个上流社会，所有的名流都到齐了。吸引他们的，除了见识不轻易对外开放的香奈儿女士宅邸的室内设计，和她收藏的中国乌木漆面屏风与沙发外，最重要的，当然就是能抢先一睹她全新推出的高级珠宝系列。

　　这次珠宝展览宣告了一个全新时代的到来。香奈儿女士打破常规，选择半身蜡像模特展示高级珠宝，而不是放在首饰盒里。这个珠宝展的主旨，并不是为了夸示保险柜里最大或最稀有的宝石，而是以女性的特殊视角，为女性设计了真正能衬托她们的美丽，并且能展现内在

　　品味的高级珠宝作品。另一项具有划时代意义的创举是色彩的统一和样式的简洁。香奈儿女士以她卓绝的品味，创造出简单大气线条的珠宝，而这，征服了眼光极高的巴黎上流社会。“无法想象还有什么能比这些星星更和谐、更华丽、更轻盈，仿佛沿着颈部曲线划出一道璀璨的光。蝴蝶结透着少女般的纯洁无瑕，而流苏款式的发饰如同后冠，焕发出梦幻的璀璨光芒。”《Candide》报这样描述。

　　而每一处细节都十分别出心裁：搭扣不复存在，每一款首饰，都能随着心情和创意，变化出多种佩戴方式。“这些丑陋的搭扣！我要把搭扣统统取消！”香奈儿女士向《L’Illustration》周刊表示。“我的珠宝作品可以随意变幻，看这条项链，它可以瞬间变成三条手链和一枚胸针……”。无搭扣，无拘无束，变化无穷。香奈儿独一无二的高级珠宝，献给崇尚自由的女性。

年关三类水晶受追捧

年关三类水晶受追捧

　　因为有“水玉”、“菩萨石”之美称,再加上招财、辟邪等寓意,水晶在临近春节的这段时间里格外受追捧.相比其他收藏类别,水晶的购买成本较低,收藏更容易入手,它也被一些人视为投资品.

　　业内人士建议,市民可留意有投资价值的水晶,如水晶球、有包裹体的水晶等,尤其是入门之前先要好“色”.

　　三类水晶有收藏和投资价值

　　很多人对天然水晶并不陌生,目前市面上最为常见的是各种水晶手链、项链,但事实上,这样的水晶没有什么投资价值.

　　“水晶其实算不上宝石,它只是一种天然的石头,产量大,更主要是用于时尚的首饰,佩戴性更强.”以珠宝设计、鉴定为特色的广州南华工贸技工学校的副校长熊英告诉南都记者,市场上的天然水晶主要是国产的,以及从巴西、捷克、奥地利等国进口的,因为做工、质地不同,它们的售价从几十元到几千元不等,“水晶产地众多,产量也大,首饰水晶的价格也主要跟品牌机构、设计做工等附加在一起,年轻人更喜欢,收藏的人少,升值空间有限.”

　　那么,选择什么样的水晶,才有收藏和投资价值呢？

　　在广东省地质研究所珠宝鉴定中心主任项贤彪看来,有三类水晶值得关注.

　　第一类是天然的水晶球.“当然,也不是随便买个水晶球就能赚钱的,主要是看你购买的水晶的大小和净度.”他说,比如最常见的白水晶,如果个儿比较大,直径在6厘米左右,净度高,裂隙少,最好一丁点裂隙都没有,那就可能会升值.而此种天然水晶球,市场价格在10万元左右.

　　第二类是有“象形物”的裂隙水晶.项贤彪介绍说,如果水晶里的裂隙,透过光来看,由于光线的折射、染色等,会在水晶里形成某种图案,即看上去像什么东西,这类裂隙水晶也有价值.他举例说,自己曾见过一个水晶球体有裂开纹路,但通过光线的巧妙碰撞,里面竟然呈现出了凤凰卫视台标的图案,卖得很贵,大概十几二十万元.在一次展览会上,他还看到过一个水晶球体里呈现的图案像观音,其开价也在一二十万元.

　　第三类是内里含有包裹体的水晶.这种水晶的晶体没有杂质,但是会有一些特色包裹体在视觉上呈现出蕴含意境的图案,从而引来不少人的追捧.

　　碧玺非水晶 水晶非宝石

　　除了上述三类水晶,无论是在街边小店还是在网络上,不少卖家还喜欢宣传说碧玺也是水晶里值得投资的品种.不过,业内人士纠正说,从严格定义上来讲,碧玺并不是水晶.

　　“我们也听说有不专业的商家把一些低档碧玺和水晶放在一起销售,说碧玺就是水晶的一种,使得很多人搞不清楚两者概念,以为碧玺就是一种价格不高的水晶.”熊英说,这种笼统的划分不准确,碧玺和水晶是两种不同的矿物,二者的价值也相差很大.

　　据了解,在珠宝界里碧玺属于中高档宝石,优质的碧玺比钻石还要稀少,一串成色上好的碧玺价格多在上万元,而水晶则属于一般的石材.现在很多商家之所以说“碧玺是水晶的一种”,是因为水晶的知名度要远远大于碧玺的原因.

　　此外,让消费者容易犯迷糊的还有水晶洞摆件.据记者在一些销售水晶洞摆件的门店看到,它们的价格多在数百元到数千元,因为水晶洞有“招财聚宝”之寓意,很多人在购买之时还很关心它的升值空间.

　　“水晶洞,好意头的成分更多,不名贵.”项贤彪说,水晶洞摆件虽是天然水晶、没被加工的原石,不过大多数的个头比较小块,只能做小首饰.从来源上看,它们很多是从国外大批量进口而来的,产量很大,在交易市场上是按公斤来称,而宝石界对珠宝称重多是按克拉、件来计,由此可见,水晶和宝石属于两个不同的概念,水晶洞重在意头足.

　　点石成金

　　投资要重“色”,黄水晶较佳

　　从颜色上来看,水晶有紫色、茶色、褐色、绿色、黄色等,颜色不同,它们的价值也有差异.因此在投资之前,要先学会“好色”.

　　紫水晶的量很大,它的价格并不高,百多元一串的手链很多.项贤彪介绍说,从颜色上来看,因为天然产出比较少,黄色水晶会比较贵.比如,黄水晶一厘米、一点几厘米的一串手链,价格也要一两万元.熊英补充说,绿水晶、红水晶也比较难得,购买时可留意.

　　此外,在水晶家族里,最不容易造假的是发晶.据了解,发晶是水晶的一种,因其中含有一些形态犹如发丝状的矿物包裹体而称为发晶,发晶一般是自然生成,没有什么规律,人工作假或是通过高温炸裂的方法作假是很难出现发丝.

　　“发晶受到人们喜欢,主要也是有象形图案在里面,当然并非所有人都喜欢,很多也达不到收藏价值.”项贤彪说.

　　TIPS

　　各色水晶之寓意

　　白水晶:镇宅、辟邪

　　紫水晶:代表高洁坚贞的爱情,常作为情侣的定情石

　　紫黄晶:象征着智能与财富

　　黄水晶:聚财,属财富水晶

　　绿幽灵水晶:别称“鬼佬财神”,色彩跟美金相似,吸引财富

　　粉晶:帮助追求爱情

Young engineers speak out at DesignCon

Young engineers speak out at DesignCon

SANTA CLARA, Calif. – The next generation of engineers wants more role models, a society more tolerant of female professionals and all the messy imperfections of people who like to pull things apart--and as much encouragement as they can get. Otherwise, they are coming along just fine, thank you.

That was the message from a panel of five young engineers at DesignCon here. Most credited parents and teachers with getting them on the engineering path.

“My dad is an engineer and he said I could do whatever I wanted as long as it was engineering, but up until last year I thought engineering was one of the most boring things you could do,” said Shachi Nandan Kakkar, a high school senior from Cupertino, Calif.

After his father encouraged him to write a blog for EDN, he realized “engineering is more interesting than people give it credit for—it’s so broad, there’s hundreds of things you can do, so find your niche and go after it,” he said.

A female high school physics teacher was mentor to Amanda Pratt, now working on a masters in engineering at the University of California at Berkeley.

“It was my favorite class from the first day, thanks to encouragement from her and my father who is an engineer,” said Pratt who has been accepted to the 2016 class at the Harvard Business School. “I decided I wanted to do something that mattered and have a career with an impact,” she added.

“I’m an engineer by birth,” recalled Andrew Milluzzi, 23-year-old doctoral student at the University of Florida. “Once I was playing with Legos and my Mom said, ‘one day you will be an engineer,’ and I said, ‘but, Mom I don’t want to drive trains,” said Milluzzi who went on to become one of the youngest LabView architects certified by National Instruments.

学会看翡翠鉴定证书

学会看翡翠鉴定证书

　　市场上稂莠不齐的翡翠,确实真假难辨,一个最有效鉴别翡翠真伪的办法就是让销售商家出具国家承认机构的翡翠鉴定证书.消费者在购买中、高档翡翠饰品时,应向商家问所购的饰品是否有鉴定证书,若有鉴定证书,应查看证书上是否有“CMA”、“CAL”或“CNAL”等标志,另外需要查看:

　　CMA——是检测机构计量订证合格的标志,具有此标志的机构为合法的检验机构.

　　CAL——是经过国家质量审查认可的检测、检验机构的标志,具有此标志的机构有资格作出仲裁检验结论.

　　CNAL——是国家级实验室的标志.

　　1、只有是天然 A 货,才会出具结果是"翡翠"的证书；

　　2、如果是B货翡翠,在证书的鉴定结果一项会标明"翡翠(处理)"、"翡翠(注胶)"、"翡翠(B货)"或"翡翠(优化)"；

　　3、C货翡翠,会标明"翡翠(染色)"；

　　4、D货翡翠,在鉴定证书结果一项中,不会出现"翡翠"字样,是什么代用品,就标明这种代用品的名称——比如"人造玻璃"、"染色石英岩"、"岫玉"、"马来玉"等.

　　5、证书应该一一对应,即一件东西一张证书,而且证书上应该有该件货品的图片及重量.虽然有些东西出自一块原料,外表看起来很相似,但翡翠饰品没有一模一样的.一件东西做了证书,并不能证明整批东西的质量——有的商家为了节约成本,只有一个作为样品的证书,照片上的货品与实物也很相似——这并不能断定他们所卖的这一批货品都是天然的,这是不符合国家规定的.

　　6、一些翡翠的基本物理、化学、光学特征标明在证书上,例如:

　　折射率:1.66(这是翡翠本身特有的与其他宝石不同的折射率)；

　　密度:3.33(也是翡翠与其他宝石区分的特性)；

　　放大检测:纤维交织结构(这是翡翠特有的一种结构).或片状闪光结构 ；　　

　　吸收光谱:437nm 吸收线(是翡翠特有的吸收光谱)；

　　滤色镜检查:无反应(有些染色翡翠在滤色镜下会变成红色)；

　　光性:集合体(翡翠是微矿物集合体)；

　　荧光性:无(有些B货在注胶后会有荧光反应)；

　　外观特征:玻璃光泽(有些B货会呈现蜡状光泽).

London Calling: Flash Forward at the leading edge?

London Calling: Flash Forward at the leading edge?

SanDisk Corp. (Milpitas, Calif.), a leading supplier of data storage products, has announced it intends to begin the transition of its flash products to 1Y-nm generation semiconductors in the third quarter of 2013.

The company is already producing high volumes of 19-nm based products, more than 50 percent of its output in 4Q12, although 24-nm flash memory will have a "tail" that will last throughout 2013, the company said in a recent conference call to discuss its 4Q12 financial results.

In fact SanDisk's announcement means that Flash Forward Ltd., a manufacturing joint venture between Toshiba and SanDisk with a relatively new Fab 5 300-mm wafer fab at Toshiba's Yokkaichi campus in Mie prefecture, Japan, will be making close the most miniaturized commercial integrated circuits in the history of the semiconductor industry. That is unless one of the few rivals, IM Flash Technologies, Samsung or SK Hynix can get there first.

The SanDisk roadmap has the 1Y-nm process lowering the cost of 128-Gbit memory ICs in 2013 and a 1Z-nm process taking monolithic memory to 256-Gbits in 2014. But judging who is most miniaturized all depends on how you define the 1Y-nm generation.

Over the last few years flash memory producers have started to become increasingly coy about declaring the minimum feature size of their processes. It started when one of the companies, I forget which, started talking of 30-nm class and 20-nm class manufacturing processes. By this the company meant a process with a minimum geometry between 30-nm and 39-nm and between 20-nm and 29-nm, respectively.

The other manufacturers quickly followed suit.

The psychology seems to be that if a company went public with the geometry detail before they got into volume manufacturing there would be concerns that a rival would somehow trump them and steal business. Of course once a product is out on the market it is possible for reverse engineering consultancies to cross-section chips and make independent assessments of the minimum geometry.

This is way of labeling chip generations is slightly different to the logic business where for each node a number is given but the nomenclature is becoming increasingly arbitrary. We have the prospect of 16-nm and 14-nm FinFET nodes coming in 2013 or 2014 that will use 20-nm back-end processes and are effectively 20-nm processes.

What we now know is that for Flash Forward, Toshiba and SanDisk, the 2X-nm node is a 24-nm node, while the 1X-nm node is 19-nm node. This would seem to put 1Y-nm at somewhere around 15-nm or 14-nm. That would give some room for the 1Z-nm generation to come in at 11- or 10-nm, which is now being touted as the last possible generation of NAND flash. We will see.

We have the prospect of 16-nm and 14-nm FinFET nodes coming in 2013 or 2014 that will use 20-nm back-end processes and are effectively 20-nm processes.

What we now know is that for Flash Forward, Toshiba and SanDisk, the 2X-nm node is a 24-nm node, while the 1X-nm node is 19-nm node. This would seem to put 1Y-nm at somewhere around 15-nm or 14-nm. That would give some room for the 1Z-nm generation to come in at 11- or 10-nm, which is now being touted as the last possible generation of NAND flash. We will see.

London Calling: Flash Forward to make the most miniaturized chips?

London Calling: Flash Forward to make the most miniaturized chips?

SanDisk Corp. (Milpitas, Calif.), a leading supplier of data storage products, has announced it intends to begin the transition of its flash products to 1Y-nm generation semiconductors in the third quarter of 2013.

The company is already producing high volumes of 19-nm based products, more than 50 percent of its output in 4Q12, although 24-nm flash memory will have a "tail" that will last throughout 2013, the company said in a recent conference call to discuss its 4Q12 financial results.

In fact SanDisk's announcement means that Flash Forward Ltd., a manufacturing joint venture between Toshiba and SanDisk with a relatively new Fab 5 300-mm wafer fab at Toshiba's Yokkaichi campus in Mie prefecture, Japan, will be making close the most miniaturized commercial integrated circuits in the history of the semiconductor industry. That is unless one of the few rivals, IM Flash Technologies, Samsung or SK Hynix can get there first.

The SanDisk roadmap has the 1Y-nm process lowering the cost of 128-Gbit memory ICs in 2013 and a 1Z-nm process taking monolithic memory to 256-Gbits in 2014. But judging who is most miniaturized all depends on how you define the 1Y-nm generation.

Over the last few years flash memory producers have started to become increasingly coy about declaring the minimum feature size of their processes. It started when one of the companies, I forget which, started talking of 30-nm class and 20-nm class manufacturing processes. By this the company meant a process with a minimum geometry between 30-nm and 39-nm and between 20-nm and 29-nm, respectively.

The other manufacturers quickly followed suit.

The psychology seems to be that if a company went public with the geometry detail before they got into volume manufacturing there would be concerns that a rival would somehow trump them and steal business. Of course once a product is out on the market it is possible for reverse engineering consultancies to cross-section chips and make independent assessments of the minimum geometry.

This is way of labeling chip generations is slightly different to the logic business where for each node a number is given but the nomenclature is becoming increasingly arbitrary. We have the prospect of 16-nm and 14-nm FinFET nodes coming in 2013 or 2014 that will use 20-nm back-end processes and are effectively 20-nm processes.

Broadcom rolls SoC switches for enterprise

Broadcom rolls SoC switches for enterprise

PORTLAND, Ore.—Broadcom Corp., which already boasts that 99.98 percent of all data traffic crosses one of its chips, rolled out Monday (Jan. 28) a new portfolio of system-on-chip (SoC) switches for the enterprise—from wiring closet to datacenter—as well as a for smaller and medium-sized businesses.

"Our newest additions to the popular StrataXGS Series simplify the provisioning and monitoring of mobile user traffic," said Nikhil Desai, product line manager at Broadcom. "StrataXGS provides a secure, seamless and high-speed connection to the enterprise data center or cloud-computing resource."

The three new StrataXGS members combines gigabit Ethernet switching and routing with an ARM-core, IP firewall, WLAN controller, network virtualization, 40G stacking, and are designed for connecting the entire enterprise, from wiring closet to datacenter to cloud-storage resources.

Switching and routing 120Gbits per second line-rate from large forwarding tables, the new StrataXGS SoCs also apply deep-packet inspecting techniques to distribute firewall functions across all access ports. Called App-IQ, it allows IT to monitor and control provisioning of wireless access points in a unified view with wired resources.

Broadcom (Irvine, Calif.) also announced what it claims is the world's smartest switch SoC for small to medium business. As the newest addition to its StrataConnect Series, the latest entry features advanced power management techniques that batch-and-burst network traffic, in order to keep the switch in low-power mode as much as possible.

"StrataConnect is switch system-on-a-chip (SoC) that brings enterprise-class features to the network of the small-to-medium business (SMB)," said Sanjay Kumar, product line director for SMB at Broadcom. "The StrataConnect SoC combines Layer 2 and 3 switching, 16-gigabit Ethernet PHY [physical layer] transceivers and an ARM core onto a single piece of silicon."

The 10Gbit Ethernet switch SoC has scalable table sizes, integrated security features and an ARM core, making the StrataConnect SoC smart enough to extend the Energy Efficient Ethernet (EEE) protocol by batching and bursting network traffic, which is especially useful in small offices that must support mobile traffic, VoIP phones and cloud services.

Android benchmark gets update, publishes online

Android benchmark gets update, publishes online

SAN JOSE, Calif. -- The Embedded Microprocessor Benchmark Consortium has gathered a database comparing processor performance of some 1,500 Android phones and tablets using a new tool released in late December. Now EEMBC is working on an update of its Android benchmark that will show more nuances of Android mobile device performance at the system level.

The December update to version 1.0 of the AndEBench automatically posts results after it is run to an open, online database on the EEMBC Web site. In terms of native processor performance, the Asus PadFone 2 currently tops the list with a score of 11,558, despite the fact it has relatively little market traction.

Members of Samsung’s Galaxy family, LG’s Optimus handsets and a Sharp phone are closely packed into second, third and fourth paces with scores ranging from 11,367 to 10,334. A wide variety of other devices from many manufactures are scattered out across the performance spectrum.

Google’s Nexus 7 and 10 ranked relatively low on the native benchmark at 8,565 and 6,650 respectively. The Motorola Defy XT handset is the dog of the group, scoring just 96 points.

In terms of Java performance, the Huawei Ascend D1 Quad tops the list at 458. It is again followed by several Samsung Galaxy and LG Optimus handsets at 405 to 370. Google’s Nexus 7 and 10 fare somewhat better here with scores of 303 and 378 respectively.

The database shows Qualcomm’s wide use among phones from many vendors and geographies. It also shows a wide variety of vendors unknown in the U.S., mainly from China and India.

The next version of AndEBench will measure memory, graphics and other system features in addition to processor performance, including tasks such as GUI rendering, XML parsing and cryptography. It will also report on how a device handles a specific task, breaking down each major point in processing the job in a story board format.

It’s unclear when the new version will be ready. The working group behind it, chaired by Ronen Zohar, an Intel Android specialist, is well attended, said an EEMBC spokesman.

AndEBench can be downloaded for free from GooglePlay and the Amazon Appstore for Android. The working group is open to new participants willing to become EEMC members at a cost of $75,000 for the first year.

Chinese IC market boom predicted

Chinese IC market boom predicted

LONDON – The Chinese market for ICs is set to experience a compound annual growth rate of 13 percent over the period 2012 to 2017, five percentage points higher than the CAGR forecast for the global IC market over the same period.

The Chinese market will move from move from $81 billion in 2012 to reach $148 billion in 2017. IC Insights states that the worldwide chip market will be $389.3 billion in that year and that China is expected to represent 38 percent of the worldwide IC market (see figure below), up from 23 percent ten years earlier in 2007.

China-based manufacturing of chips is also expected to boom over the next five years but from a much lower level. IC production in China represented 11.2 percent of the $81 billion market in 2012.

A strong CAGR over the period 2012 to 2017 of 16.5 percent will take China-based IC production from about $9.1 billion in 2012 to $19.5 billion in 2017 which would only represent about 5 percent of the global chip production.

b货翡翠鉴别 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网

    翡翠玉石雕琢成的首饰品，让人欢喜让人忧。欢喜是因为现在的翡翠首饰，价格都回落了，很多人都可以买得起翡翠了。而忧愁的是，在人们开始喜欢上翡翠的时候，却出现了很多作假的翡翠首饰品。像这类作假的翡翠首饰品，一般都是称之为b货翡翠、或者是b加c货翡翠。而纯天然的就是我们所共识的a货翡翠。下面让我们来了解怎样鉴别b货翡翠。

    A 货翡翠就是在未经任何人工处理的、纯天然的翡翠玉石。a货翡翠经过多年的佩带，与人的肌肤不断接触摩擦，玉质会更加润泽，而人体也会得到保健作用，佩带者的心情也很愉悦，这便是常言所说的“人养玉，玉养人”的道理。 而所谓B 货翡翠，是将质量欠佳的天然翡翠，用酸液浸泡，使之去脏、去黄，并进行注胶（酸洗轻微时可不注胶）处理后，使其种、水、色均得到提高的翡翠。由于其关键步骤是酸洗过程，所以我国南方也称之为“洗澡”或“冲凉”翡翠。 

糯冰种癣加绿马到成功天然翡翠吊坠

    我们光知道b货翡翠的概念还没有用，我们要知道，为何还是有那么多的人不停的做b货翡翠呢？这主要是将翡翠原料加工成b货翡翠，是有这样的目的的。第一就是去除翡翠原料内部的杂质和脏色，也就是指用化学方法除去翡翠中的裂隙或晶隙间的不利绿色的黄色或黑色杂质。而第二个目的则是指增透，也就是指注入充填物于裂隙或晶隙中以提高透明度。第三点则是盖隙，也就是指利用注入裂隙或晶隙中的充填物以掩盖裂隙。其实最终的目的，也就是为了寻求高额利润，以及启用一些本来毫无成本的、人们都认为无法再用的翡翠原料。

    那么佩戴b货翡翠好不好呢？通过很多实例证明，B 货翡翠在处理过程中受到了酸的腐蚀，虽然去掉了翡翠中的脏，增加了透明度，保留了原有的绿色，增加了地与色的对比度，但翡翠的结构出现了微细裂隙和空洞，所以要在高温高压下将胶压入其裂隙和空洞中，这样翡翠的种、水、色均得到了提高，宛如高档的天然翡翠。然而，随着时间的推移，充填入翡翠的胶慢慢老化脱落，翡翠渐渐变得痕迹斑斑，失去了光彩。

B 货翡翠鉴别方法： 

    1、颜色较为鲜艳，绿色大多没有色根，色与地对比强烈，不自然；

    2、 光泽较弱，多呈树脂光泽，不及“ A 货”翡翠的近玻璃光泽； 

    3、 结构较为松散。放大检查可见晶体颗粒被错开、位移，失去方向性； 

    4、用宝石放大镜可观察到表面有桔皮般凹坑麻点，称“桔皮效应”； 

    5、密度和折射率通常均相对低于“ A 货”翡翠； 

    6、若注胶，则在紫外荧光灯下呈粉蓝色或黄绿色荧光； 

    7、轻轻敲击“ B 货”翡翠手镯，其声音发闷，而“ A 货”翡翠手镯的声音清脆悦耳。

3克拉钻石值多少钱

3克拉钻石值多少钱

　　在钻石世界，1克拉是入门水准，2克拉就有些惊艳了，而3克拉只能用叹为观止来形容，可以说是钻石界的高富帅！3克拉钻石代表了力量，奢华和永恒。在欧洲，大钻石是身份和权力的象征，常见于皇室贵族和宗教。

“非洲之星”

　　克拉是计量钻石重量的单位，一克拉等于200毫克，即0.2克，大多数钻石都不超过1克拉。比如说单钻戒指的重量一般在0.5至1克拉之间。我们说的大钻石，指的是3克拉以上的钻石，一颗3克拉钻石非常稀有而珍贵，适合用来收藏或投资，更可以作为贵重的礼物来赠送他人。

　　世界上最大的钻石是著名的库利南钻石，重达 3106.75克拉，是迄今为止发现的最大宝石级别的钻石原石。库利南钻石被分割成了105颗钻石，最大的“库里南1号”，也称为“非洲之星”，重达 530.20克拉，镶嵌在英国爱德华国王的权杖上，现存于伦敦塔内。

　　在钻石开采中，一百万颗钻石原石也不一定能出一颗1克拉成品钻石。毫无疑问，钻石越大越稀有，价格也更高。一颗3克拉钻石的价格比三颗1克拉的钻石价格要高出数倍。而钻石质量的优劣也对价格起到重要影响，国际上一般都以钻石的4C(克拉数、颜色、净度、切割)标准来衡量。所以即使是两颗都是3克拉钻石，它们的价格也因为其余3个标准的不同而相差甚远。

3克拉红钻

　　这是一枚3克拉红钻，艳丽的红色和完美的切割使得这颗罕见的红色钻石充满圣诞气息。它是美国宝石学院 (GIA)鉴定过的最大的圆形梦幻红橙色宝石，估计价值在70万-120万美元之间。

Diamondland 三克拉钻石

　　如果想拥有一款3克拉钻石首饰，我们推荐你买一枚镶嵌三颗1 克拉钻石的戒指，这个价格你绝对负担得起！ 或者像这款白金钻石戒指，镶嵌15颗约0.25克拉的圆形明亮式钻石，售价：11,170欧元(约合人民币9万元)。

翡翠收藏注意价值和用途 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网

翡翠收藏注意价值和用途 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网

    我们先来看一组数据，国内高档翡翠非常适合长线投资，近两三年来平均升值30％－50％，有些品相特别出色的升值更多。目前广州已经有越来越多的投资者选择收藏翡翠来保值、增值。具有收藏价值的宝石级翡翠只有缅甸出产，它的稀少性和资源的不可再生性，决定了它特有的投资价值。近几年，国内一些珠宝玉器拍卖会上，高档翡翠价格屡创新高，其升值之快，是古董、邮票和书画等其它投资品所难以比拟的。国内目前需求最旺的翡翠是零售价1000元至3000元的产品，其次是3000元至5000元的款式，这些大多作为饰品流通的翡翠制品，价格通常比较容易确定。

    翡翠收藏是好事，但是我们要怎样收藏和佩戴翡翠首饰品，才能不使自己的收藏显得没有眼力，或者是显得是在打水漂一样。其实收藏翡翠首饰品的时候，最主要的想法是要能达到保值增值的目的。所以在收藏翡翠首饰品的时候，一定要注重所收藏的翡翠首饰品，是有高价值的。翡翠的价值主要从其颜色、质地、透明度、纯净度等方面来衡量。收藏时要选择纯正的天然正品，要讲究“种”，即翡翠的质地与结构，质地越细腻，玉质就越晶莹剔透；“色”，指颜色，色彩均匀，色正、浓、翠才是上品；“水头”，即透明度，光泽晶莹、通透清澈为上品；其次还要综合考虑雕功、题材等因素，越具艺术性价值越高。

冰玻种蓝水熊猫天然翡翠吊坠

Kotura preps fab deal amid silicon photonics surge

SAN JOSE, Calif. – Add Qualcomm to the list of ARM server SoC designers. The smartphone chip designer is advertising at least three software engineering jobs that clearly state its intentions.

Applicants will work on "architecture/design and system prototypes of Qualcomm's new ARMv8-based server SOC ASICs for the power optimized server market," the ads say. "Primary responsibilities include specification, development, porting, integration and shakeout of server platform management software and firmware on prototypes utilizing Qualcomm’s new SOC."

The ARMv8 is a reference to ARM's next-generation 64-bit capable instruction set architecture. The ability to handle 64-bit addresses is key for server processors.

Qualcomm is at least the eighth company now known to be working on ARM server SoCs. Others with announced or known plans include AMD, Applied Micro, Cavium, Calxeda, Marvell, Nvidia and Samsung.

Huawei posted job openings for ARM server engineers last year. However, it was not clear if the company is designing systems, SoCs or both. Texas Instruments rolled out ARM server SoCs, but is targeting "purpose-built" embedded systems, not data centers.

The companies known to be preparing ARM server chips generally aim to start shipping 64-bit SoCs in 2014. Calxeda and Marvell are shipping 32-bit SoCs for servers today with limited traction, mainly in prototyping systems for Dell, Hewlett-Packard and Taiwan’s Mitac.

The Qualcomm software jobs appear to be mainly in Raliegh, N.C., although at least one also lists postings in Austin and San Diego, Qualcomm’s headquarters.

FLAGSTAFF, Ariz.--Belkin said Thursday (Jan. 24) it will acquireCisco’s Home Networking Business Unit, which includes the Linksysproducts, for an undisclosed sum. The acquisition willgive privately held Belkin, based in Playa Vista, Calif., a 30percent of the U.S. retail home and small business networkingmarket.

Currently, Belkin has a range of wired, wireless and powerlinenetworking products under the Belkin brand. Company officials saidthey will maintain the Linksys brand. Cisco acquiredLinksys for $500 million almost exactly 10 years ago,as the networking giant expanded its reach into home-networking.

The company spent years trying to find its way in the consumerworld only to begin to unwind or kill those investments beginninga few years ago, most notably endingproduction of the popular Flip video camera as smartphones took over that application.

Chet Pipkin, CEO of Belkin said, "Belkin’s ultimate goal is to bethe global leader in the connected home and wireless networkingspace and this acquisition is an important step to realizing thatvision.”

Specific financial terms of the transaction are undisclosed. Thetransaction is subject to various standard closing conditions andis expected to close in March 2013.
