摘要
介绍了一种集四端子接法、电流换向及动态测量于一体的方法,通过该方法来获得测量数据并进行恰当的处理,就可以合理地抵消掉热电势对测量带来的影响,能够较好地完成对高温超导体电阻特性的精确测量。
Introduced one method consisting of four-probe means, electric current exchanging technology, and dynamic measurement. Obtained metrical data through this method and appropriate processing, may reasonably counter-balance an influence which came from heat electric potential, and could complete well precisice measuring for resistance characteristic of high temperature superconductor.
