摘要：

This　article　investigated　typical　abnormal　seismic　electrical　signals,　which　were　received　by　seismic　electrical　pulse　instrument　located　in　Beijing　University　of　technology,　and　the　carried　out　frequency　analysis　by　theory　of　Fourier　Transform　and　Wavelet　Transform,　finally　found　out　the　frequency　characteristics　and　the　frequency　range.　The　results　show　that　the　above　mentioned　abnormal　seismic　electrical　signals　are　useful　ground-wave　signals.
