摘要
详细叙述了利用普通收音机在短周期测震记录仪上打授时台秒号的接口,它的设计原理、安装与使用。经实践、成本不高,性能确可满足需要。
In this article,we have in detail discribed the design princples,installation and usage of the interface for giving time-signala in the record ob short-period seismograph using common radios.The practice has proved that it can meet the user's requirements with low costs.
