摘要
即将应用于国家数字地震台网的JCZ-1甚宽频带地震计,具有从20Hz至直流的宽频带平坦响应,是真实记录地面运动的高性能仪器。本文介绍它的地震数据记录系统、传递函数,并就几个典型震例介绍了甚宽频带记录特征和某些数据预处理的方法。
The JCZ 1 ultra broadband seismometer which will be deploged on the State Digital Seismographic Network of China has very broadband flat respouse for ground velocity. It is a high quality instrument which could record the movement of the earth surface truly. This paper introduces its seismic data recorder system, transfer function. Several earthquake samples show its broadband features and some data processing methord.
