对短波电台发射时干扰地震仪的机理进行了分析。指出干扰形式及干扰噪声进入地震仪的端口，用抗干扰三要素理论结合地震台、站实际条件，采用低通网络抑制干扰，收到了明显的效果 The mechanism of interfering seismometers when launching shortwave radio was analyzed. It is pointed out that the form of interference and the noise entering into the seismograph’s port, and using the three elements of anti-interference theory combined with the actual conditions of the seismic station and station, the low-pass network is used to suppress the interference and the obvious effect is received
