摘　　要：通过对感应雷危害无线遥测地震仪的机理、频谱进行了研究,发现感应雷能量、频谱远低于仪器射频信号频率,从而提出了将仪器天线感应的雷电信号分离出来导入大地的“波道分流”理论,并在实际应用中解决了无线遥测地震仪感应雷防护的技术难题。Energy and frequency spectrum of inducing lightning was proved to be much lower than that of radio frequency signal of seismic instrument by careful study on the cause of inducing thunder. Then the theory of 'wave channel distribution' by means of separating thunder and lightning signal from radio signal then leading it into the earth was advanced. This way presented a good solution for induced thunder prevention in field operation.
