热电式仪表
The phases of samples were analyzed by X-ray diffraction and their thermoelectric properties were tested by electric constant instrument and laser thermal conductance instrument.
用X射线衍射分析了样品的相组成,用电常数测试仪和激光热导仪测试了样品的热电性能。
It is proved by controllable metal experimental instrument: thermoelectric potential field exists in cooling hot metal of cast iron, which is point electrical potential field, and its life is approximately 0 05  ̄ 3 58s.
用金属型可控实验仪证实:进行冷却的铸造铁水内部存在着温差电势场,且为点电势场,其寿命约为0.05~3.58s。
