| 摘 要： | 定量地实验研究了在采用不同观测方法相同干扰对视电阻率测量的影响。结果表明，采用正反向供电方法可大幅度提高视电阻率的观测测精度。同时还在ＺＤ８地电仪上实现了这种观测方法，试验结果与理论推算值基本相符。

| Abstract: | In the paper, influences of the same interference on measurement results of apparent resistivity are quantitatively studied by using different observational methods. It is shown that observation accuracy of apparent resistivity could be improved greatly through up-down transmission. This observation method is applied to ZD8 geoelectric instrument and experimental results can be reproduced by the theoretical calculations basically. |
