摘　　要：在电法勘探中,常需要测量接地电极的接地电阻。测量接地电阻用万用表进行测量时,极化电位会影响到测量的准确性。从极化电位机理和万用表电阻测量原理出发,分析了极化电位给接地电阻测量带来的影响,同时讨论了改善结果的方案。It is necessary to measure the earth resistance of grounding electrode in electric method prospecting. When using multimeter to measure the earth resistance,the existence of polarization potential will affect the accuracy of measurements in theory. Based on the mechanism of polarization potential and the principle of measuring resistance through multimeter,it is studied that the influence to the measurements of earth resistance caused by the polarization potential,and then it is discussed that the improvement scheme measure erath resistance.
