摘　　要：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。The mechanism for short wave radio station to disturb seismic instruments has been analyzed in this paper.It is pointed out that the interference is due to the entrance of seismic instruments.Having used low pass network by means of the interference free theory combining practical station condition,the effect of rejecting interference is obvious.

关 键 词：短波电台 地震仪 干扰机理 抑制法
