【摘要】 介绍吉林测震台网数字台站仪器配置,对台网31个测震台站台基噪声功率谱进行计算,得出各地震台台基的地动噪声的均方根值、观测动态范围、地噪声功率谱,并将计算地动噪声功率谱作为吉林地震台网资料分析处理的一项日常工作进行。更多还原

【Abstract】 In this paper,instrument configuration of Jilin Digital Seismic Station has been introduced,and station base noise power spectra of 31 digital seismic stations in Jilin have been calculated,and mean square root values,observational dynamic range and ground noise power spectra of all seismic station bases have also been calculated.Station bases of all Jilin seismic stations have been assorted into 3 types according to those results.In order to obtain the varied information of station ground noise,we have counted the work of calculating ground noise power spectrum into daily routine.更多还原
