Chapter 2: The chapter concentrates on the powerful instrument in studying the carrier transport properties—thermopower.. Starting with the base theory, the chapter discussed the thermoelectricity phenomenon in metal and semiconductor in detail, including the useful Mott formula, phonon drag effect (normal process and Umklapp process), abnormal thermopower in transition metal, two-band model, magneton scattering, and so on. To resolve the abnormal thermopower in low temperature, some theoretical models, such as the distortion of Fermi surface, resonant scattering, spin-bag model, were argued. Each of them has its limition.

第二章：对热电势这一研究物质载流子输运性质的手段进行了综述，从热电势的原理和基础理论研究开始，针对金属和半导体的热电势现象进行了详细讨论，包括研究工作中常用的Mott公式、声子曳引的正常过程和Umklapp过程、过渡金属异常的热电势现象、双带模型及磁子散射机制等等，对于低温下的异常散射机制讨论了声子曳引、费米面畸变、共振散射机制、自旋口袋模型等若干种理论模型及其局限性。

As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.

像所有金属一样，这些金属既有好的延展性也易锻造，并且是电和热的良导体。

Earlier this year, signs of corrosion were found in metal strips made by Mantegazza of Italy for more than - 500m worth of notes destined for eight eurozone countries.

今年早些时候，在意大利曼泰加扎公司生产的金属条上发现有腐蚀的痕迹。这些金属条是为发往8个欧元区国家的价值5亿多欧元的纸币制造的。

The planning of the processing parameter is based on the plastic deformation of the metal because the planning of the cold rolling technique is affected by the ability plastic deformation of the metal. Industrial PC is the master processor of the cold rolling machine. The process of cold rolling monitored by the corresponding functional component real-timely.

冷辗工艺的设计受金属塑性变形能力的影响，因此工艺参数设计以金属塑性变形为基础；冷辗机控制系统以工业PC为主控制器，通过相应的功能模块实现对冷辗进程的实时监控。

Metal matrix compesites can compete with traditional matal matarials and have a broad prospect in civil products because of their excellent mchanienl properties and their forming technology being perfected.

金属基复合材料的优异性，能以及日益完善的成型工艺，使其可与传统的金属材料竞争，在民用产品中具有广阔的应用前景。

Strong antidumping property: When titanium is affected by mechanical vibration or electric oscillation, its vibration damping time lasts the longest time, compared to that of steel and copper.

抗阻尼性能强：金属钛受到机械振动、电振动后，与钢、铜金属相比，其自身振动衰减时间最长。

In a laboratory test, a bare metal strip is placed in a solution of ice melter with corrosion inhibitor and water. No corrosion occurs because the pacifying agent moves freely in the water and coats the metal.

试验室试验，是将裸露金属浸入含阻锈剂的融雪剂水中，这样阻锈剂在水中可以自由移动并覆盖金属，试验结果会没有腐蚀发生。
