本文介绍荷泽台地电阻率周期成分分析方法及其结果,对南北向地电阻率趋势性异常进行了解释。前言 在震情监视工作中经常遇到观测值曲线存在周期性变化的问题。这种变化往往把地震信息掩盖或歪曲了。为了正确认识与周期变化迭加在一起的地震信息,首先识别周期 This paper introduces the Heze station resistivity periodic component analysis method and its result, and explains the north-south geo-resistivity trend anomaly. Foreword In the earthquake monitoring work often encounter the problem of periodic changes in the observed value curve. Such changes often mask or distort seismic information. In order to correctly understand the seismic information superimposed with the periodic changes, we first identify the period
