A new diamond search algorithm for fast-matching motion estimation is proposed to replace the traditional three-step search algorithm in the motion estimation region.

并且针对块匹配运动估计给出了一种改进的钻石搜索算法代替原有的三步搜索法。

Tantalum is an ideal material for hot cathode. It has a low electronic work function, high melting-point, low evaporativity, and good mechanical, high-temperature, chemical properties. Especially in a PCVD ambient for diamond film deposition, its surface is transformed into tantalum carbide which has a much higher melting-point, lower evaporativity and better properties of electron emission.

钽是一种理想的热阴极材料，它具有电子逸出功低、熔点高、蒸发率小、良好的机械性能、高温性能、化学稳定性等优异特点，尤其是在辉光放电PCVD制备金刚石膜的特殊气氛中形成的碳化钽表面层，具有比钽更高的熔点、更低的蒸发率和更好的热电子发射特性。

We present a configuration of the diamond four-level, in which consist of V-three-level and an upper excited state.

在V-型三能级系统的基础上加入一个较高的激发态，便构成了一菱-型四能级系统。

He is a successful exporter of diamond.

他是一个成功的珠宝出口商。

Our old Fagin is back. The Diamond Dog.

看来我们的老法师重返江湖了钻石狗

The variety of olivine include olivine, peridot, flinder diamond, forsterite, fayalite, dusk emerald and sinhalite.

橄榄石的种类包括（贵橄榄石、黄玉、镁橄榄石、铁橄榄石、"黄昏祖母绿"和硼铝镁石）。

While a genuine heart is never easy to come by, this unique shape has become one of the most popular cuts. Several years ago Ferri held a Perfect Fancy Cut Diamond Show.

最初一颗钻石晶体不切磨成圆，是因为不适合，如果硬是要切磨成圆形，原石的损耗太多，不符经济原则；於是依其原石情况，在最具效益的情况下，将它们切成各种形状。

Designed as a double festoon of circular cut diamonds in collet, spaced by diamond baguettes and graduated in size from the centre, the sides and clasp decorated with similarly set open-work plaques, the back supporting two drops with large circular cut diamonds and baguettes.

宝石座上镶嵌圆形切割钻石的双层花彩设计，中间间隔长方形钻石，尺寸从中央逐渐减小，两侧和搭扣装饰以相似方式镶嵌的镂空金属片，后部悬挂两个吊坠，镶嵌大颗圆形切割与长方形钻石

Compared to the germanium, a common material used in infrared field, chalcogenide glasses possess the characteristics of low-cost and the little value of dn/dt. Besides, it is amorphous glass, which is produced the spherical and aspheric lens by using a molding process instead of single-point-diamond turning. Thus the mass manufacture cost of infrared lens will drop obviously, the stability and consistency of product is guaranteed.

相对于红外领域常用的材料单晶锗，硫系玻璃不但具有低成本，折射率随温度变化小的特点，而且，由于它是非晶态材料，可以用精密的模压工艺来代替用于晶体材料的单点金刚石车削工艺，其批量加工的成本得到了大幅的降低，产品的稳定性，一致性也得到了明显的提高。
