摘　　要：通过多项实验观测对电阻率测值与电流出现相同趋势性变小的原因进行了探讨分析,认为这是装置系统的重要构成部分即电极发生了变化,从而导致了电阻率测值的趋势性下降。This paper analyzed the reasons why the resistivity measurements has occurred the same decreased trends with the current through a number of experimental observation, based on the comprehensive discusses, we think that the change of the electrode which is the important constitute part of the device system thus resulting in descending trend of measured value the resistivity.
