冶金学

Just as Crile a western metallurgy specialist said, they would not be better than those made in Chinese Shang Dynasty even if the most skillful machinists from America and Europe co-operate using modern technologies to make them.

正如国外冶金学权威克里尔说的"即使把美国和欧洲第一流的技师集合起来，并使用现代的科学技术，也不能做得比殷商青铜器更好。"

Because of the development of hydrometallurgy, these ores have been paid attentions as significance exploration targets now.

由于湿法冶金学的发展，这类矿床正在成为引人注目的勘查目标。

Hydrometallurgy: Extraction of metal from ore by dissolving the metal and then recovering it from the solution.

湿法冶金学：将矿石中的金属溶解，再从溶液中回收金属的提取方法。

Wang Changqi from China Institute of Aerodynamics （ he is the inventer of the first Supersonic Jet Pulverizing in China ）, we have successfully produce three Supersonic, Cryogenic, Fluidized Bed Superfine Powder Pulverizing/classifying equipment , their type is CF26、 CF29、 CF50, they could be used in large-scale production and laboratory.

我厂是专业从事超流化床超微粉碎分级设备生产厂家，本企业汇集了空气动力学、结构力学、金属材料学、机械制造学、粉末冶金学等学科的相关专家，在中国空气动力学专家王昌棋将军(中国首台超音速气流粉碎机发明者)主持下，成功地研制、开发出适应大规模生产和实验室研发用以极规模生产用 cF26、 cF29、 cF50三种系列多种规格的超音速、超低温、流化床式超微粉碎分级系统设备。

The temperatures in the start and end of each stage are among the most critical parameters for the metallurgist to schedule, because the metallurgical transformations and finish steel properties are tightly related to the transaction temperatures.

每一个阶段的开始温度和结束温度是冶金师要安排的最关键的参数，因为冶金学转变和钢材轧后性能是与转变温度紧密相关的。

As I know metallurgy is the art and science applied to metals.

据我所知，冶金学是适用于金属的技术和科学。

Silicon is also used in metallurgy as a reducing agent and in steel, brass, and bronze.

在冶金学上，硅也可用作还原剂，并用于钢铁、黄铜和青铜中。

Presents the microstructure evolution in aluminum a nd copper after deformation by cold rolling in the strain range of 10 to 50%red uction using TEM and points out three types of dislocation structures are typica l and two of them are common for both materials and these two common types are f ound in non-cube grains and can be distinguished by crystallographic orientatio n of dislocation boundaries in the grains and the third type of structure is obs erved in cube grains, and concludes that grain orientation is important in deter mining the structure type but some other metallurgical parameters also have a ro le to play.

采用TEM对冷轧多晶铜与多晶铝的形变显微组织演变进行了对比研究。结果发现：多晶铜及多晶铝形变显微组织中均含有三类典型的位错结构类型，其中的两种结构特征在两种材料中是相似的，这两种类型结构存在于非立方取向晶粒，可通过晶粒中位错边界的晶体学取向加以区别，另一类型结构存在于立方取向晶粒；晶粒的晶体学取向决定了其形变显微组织类型，但其它冶金学因素对显微组织也有影响。

This problem maybe related to metallurgy and the manufacturing process of the implants used in these patients.

这可能和这些病人所使用的假体的制造过程以及冶金学有关。

Just as Crile a western metallurgy specialist said, they would not be better than those made in Chinese Shang Dynasty even if the most skillful machinists from America and Europe co-operate using modern technologies to make them.

正如国外冶金学权威克里尔说的&即使把美国和欧洲第一流的技师集合起来，并使用现代的科学技术，也不能做得比殷商青铜器更好。&

It is also known as one of the most poisonous naturally occurring substances.

它也被称为一个最自然发生的有毒物质。

The greatest stress is found at the location on the cross section where V is the largest.
