在对CR-2-69型Z分量磁力仪的相对观测资料进行分析时,除应考虑外空变化场的影响及背景场的长期变化影响外,如何正确识别由于温度变化所造成的形态年变化,进而消除这种温度影响,对提高观测资料的使用价值是十分重要的。本文以徐州地震台几年来的连续观测资料为基础,结合省内同类仪器一定时间段的观测资料,讨论如何使用观测资料来确定CR-2-69型磁力仪的温度影响。
In analyzing the relative observational data of the CR-2-69 Z-component magnetometer, it is necessary to consider accurately the annual change of the shape caused by the temperature change, in addition to considering the influence of the outer space change field and the long-term variation of the background field , So as to eliminate the influence of such temperature, it is very important to improve the use value of observation data. Based on the continuous observation data of Xuzhou Seismostation over the past few years and the observed data of similar instruments in the province for a certain period of time, this paper discusses how to use the observation data to determine the temperature influence of the CR-2-69 magnetometer.
