纯金

Since there is an infinite number of nonmetallic materials as well as pure and alloyed metals,considerable study is necessary to choose the appropriate one .

由于非金属材料与纯金属和合金的种类都比较繁多，所以在选择合适的材料时需要做大量的研究工作。

Because special properties can be obtained by alloying, few pure metals are used extensively.

由于特殊的性质可以得到合金，很少有纯金属广泛使用。

The petals of these flowers were of pure gold, and the calyxes were of diamond.

这些花朵的花瓣是纯金构成，并且花萼饰满了钻石。

She has beautiful long blonde shining hair, full of curls and wings of pure gold.

氰化亚金钾，又称亚金氰化钾，化学式为KAu2·2H2O，白色结晶或粉末，无水物的比重为3.45×103mg/m3，熔点200℃，溶于水，微溶于酒精，不溶于乙醚，有剧毒，主要用于纯金的电镀和用作化学试

Founded in 1997, Shenzhen good Tai Fook jewelry Ltd, is a professional design, production, Marketing electroformed pure gold silver handicrafts enterprises.

创立于1997年的深圳好大福珠宝首饰有限公司，是一家具有专业设计、生产、营销电铸纯金纯银工艺品的企业。

These series of alloys were selected because of their important applications to mechanical machining and national defence, and the lack of information of their specific heat capacities in supercooled region.

在此之前，由于实验数据的缺乏，往往采用外推法或者利用理想溶液模型从纯金属的比热数据中推导得深过冷的比热数据。

Project Content and Scale: To adopt a mixed production transmission device of micro glass powder such as axle bush, the anti-abuse movement capacity of gears can be raised 2-3 times, especially in the condition of high-temperature without lubricant .About 70% of the world automobile gear is made in the way of metal powder metallurgy. However, utilizing method of pure metal powder metallurgy may cause a fatal weakness, that is, because sinter oxide membrane will arise among crystal, this may lower its intensity.

项目内容和规模：采用微玻粉末混合生产的传动装置如轴瓦，齿轮其抗磨蚀能力提高2—3倍，特别在高温无润滑条件下优势更为明显，全世界70%的汽车齿轮是用金属粉末冶金为法制造的，但纯金属粉末冶金件有一个致命弱点，因颗粒间会产生烧结结氧化膜而降低强度。

A banner hoisted on a pole is also fastened at the stern and the hull is decorated with red, green and blue scales edged in gold.

迎风招展的旗帜被紧固在船尾一角；船身则被漆成鲜亮的红、绿、蓝三色，并以纯金镶边。
