摘要
新建国家数字地震台网所使用的CTS 1甚宽频带地震计是一种具有甚宽频带、大动态范围、高灵敏度负反馈地震计。介绍了地震计的系统组成及工作原理。用多种方式给出了系统的传递函数 ,描述了仪器设计要点和系统测试 ,对仪器工作环境给予了特别的注意。最后简要介绍了地震计的应用情况。
The CTS-1 very broadband seismometer employed in New State Digital Seismic Network is a seismometer of very broadband,large scale dynamic and high sensitive feedback . This paper introduces its system and operational principle. The transfer function of the seismometer is given in different ways. The design ideas and system test are described.The authors pay special attention to working environment of the seismometer.Finally,the application of this instrument is brifed.
