摘要
利用电阻率及热电势等物理性质研究液态金属及液态合金的前提是得到高精度的数据,而数据精度取决于测量方法。主要介绍了测量电阻率所常用的接触法和非接触法,测量热电势的微差法及各种方法的优缺点。
In the process of studying liquid metals and alloys using electrical resistivity and thermopower,it is necessary to obtain highly accurate data,which depends on measuring methods.This paper presents a review of the contact method and non-contact method of measuring the resistivity,and the method of electromotive force produced by the temperature gradient for measuring the liquid metals thermopower is also introduced.At the same time,the ad- vantages and disadvantages of the methods mentioned are pointed out.
