我厂的地震测报组是在厂党委领导下和上级地震领导机关的指导和帮助下建立起来的,于1975年2月开始测报。现在共有十二种测报手段,以土地电测报为主。在测量方法上使用两种测量仪器,其一是用微安表每日定时观测,第二是用电子电位差计自动记录二十四小时内的电位变化数值。在作图分析方面有三种方法:矢量法、平行电法和日均值曲线法。为了研究土地电变化与地震对应的内在联系,我们还因陋就简地做了一些实验和分析。现在介绍如下。
The earthquake survey team of our factory was established under the guidance and help of the leadership of the factory party committees and the earthquake leading organ of higher level, and began to measure the newspaper in February 1975. There are now 12 kinds of means of measurement to the main electricity measurement report on the land. Two types of measuring instruments are used in the measurement method. One is to observe the daily time with a micrometer ampere meter and the second is to automatically record the change of potential within 24 hours with an electronic potentiometer. There are three methods in the mapping analysis: vector method, parallel method and daily average curve method. In order to study the internal relations between the change of electricity and earthquakes, we also made some experiments and analysis simply because of the earth’s changes. Now introduced as follows.
