摘要
在SeisDps地震处理软件的实时系统中,不是用系统的幅频特性计算震级ML,而是利用台站的零点、极点和增益,将记录的数字地震波形仿真成伍德-安德森地震仪记录的波形,计算具有3 大优点的ML震级,本文主要介绍用零点、极点和增益计算ML的过程。
In the seismological real processing system software of SeisDps,ML is not calculated by amplitude-frequence but by zero point, polar point and gain of the system. It is necessary to emulate the digital seismological waves into Wood-Anderson waves to calculate ML with three advantages. In this paper, the emphasis is to introducing the process of calculating ML by zero point, polar point and gain.
