一种消除地电阻率观测中随机误差的新方法

摘要

On the basis of studies of predecessors, a new method——providingcurrent in varying period is proposed. Basic principle of the method and its use in Terrameter are analyzed. Effect of removing stochastic error of the method is simulated by the test in laboratory and computer. The results show that the method is better in removing stochastic error.%在前人研究的基础上，提出了一种消除地电阻率观测中随机误差的新方法——变周期供电法．详细介绍了该方法的原理和实施步骤．从计算机模拟和实验室模拟2个方面对该方法消除随机误差的效果进行了验证．
