摘　　要：阳原地震台地电阻率观测受外界影响严重,较大程度地影响了观测资料的精度,使资料质量大大降低。通过对外线路及周围环境的深入分析与研究,发现影响地电阻率精度的因素有漏电、电极老化、供电电源正反相供电不稳定、降雨、风扰五方面。文章针对上述干扰因素,介绍相应的排除方法,对提高观测资料的精度和质量具有重要意义。The serious influence of external environment on the earth resistivity observation largely affected the accuracy and quality of observation data. Through the further analysis and research of the external circuit and the surrounding environment, it is obtained that the factors that affect the accuracy of earth resistivity contains include leakage, electrode aging, instability of the positive and negative phase power supply？ rain, wind disturbance 5 aspects. In this paper, the corresponding elimination methods are introduced in view of the above interference factors. It has important significance to improve the accuracy and quality of observation data.
