一、概述用形变电阻率异常进行地震预报是我国目前所用的前兆方法之一,在强震预报中发挥了一定的作用.但过去多用相对变化幅度、延续时间、异常形态、异常面积等进行预报,定性较多,定量较少.因而迫切需要将这些零散的带有规律性的东西加以总结.本文以近年来我国形变电阻率的观测资料用数理统计的方法加以归纳,试图得出预报“三要素”的定量图式.为了找出形变电阻率异常面积S与震级、震中距、发震时刻的关系,我们对我国西南、华北等几个地震,五十几个地电台形变电阻率异常进行了统计分析,看出震级、震中距离与形变电阻率异常面积的对数存有线性关系.用最小二乘法原理求出一系列震级与异常面积关系曲线即异常初级量板.然后,用初级量板再进一步用理论计算重新制作适合一般形式的理论量板.
I. Overview It is one of the precursory methods currently used in China to predict earthquakes with anomalous resistivity anomalies, and it has played a certain role in the prediction of strong earthquakes. However, in the past, the relative magnitude of change, the duration, the abnormal shape and the area of anomalies , More qualitative, less quantitative.Therefore, there is an urgent need to summarize these scattered with regularity.This paper summarizes the observation data of deformation resistivity in China in recent years by means of mathematical statistics and tries to draw the conclusion that “ Element. ”In order to find out the relationship between the anomaly area S of deformation resistivity and magnitude, epicentral distance and the time of occurrence of an earthquake, we conducted a survey on the deformation resistivity anomaly of several earthquakes in China’s southwestern and northern China and so on The statistical analysis shows that there is a linear relationship between magnitude, epicentral distance and the logarithm of anomalous area of deformation resistivity, and a series of abnormal primary plate is obtained by using the least square method principle.And then, The plate is then further re-made with theoretical calculations to fit the general form of the theoretical plate.
