我省安庆地震台利用屏蔽声波的方法,排除了飞机噪声与1—3km处近炮声波对短周期测震仪记录的干扰,取得了较好的效果。台站附近小型爆破是否有地振动成分?主要是声波还是地振动?什么是主要干扰因素?为弄清这些问题,我们做了以下试验,得出了结果。一、实验方法及结果
Anqing Seismic Station in our province used the method of shielding sound waves to eliminate the interference of aircraft noise and the recorded short-period seismometers near 1-3 km at gun sound waves and achieved good results. Are there any ground vibration components in the small blast near the station? Mainly sound waves or vibrations? What are the major disturbing factors? In order to clarify these problems, we did the following tests and got the results. First, the experimental methods and results
