根据走行部故障振动信号的特点，选用调制高斯函数作为分析小波，处理由损伤冲击造成的信号突变。
The modulate Gauss function is selected as the analysis wavelet to deal with the fault signal saltation caused by the damage concussion, according to the (characteristics) of fault vibration signals.
计算表明，对于高斯激光束，冲击波阵面为一曲面，波阵面上不同径向位置的压强是不同的。
The results show that, for a Gaus-sion laser beam, the shock front is a curved surface, the pressures at different radial positions on the wave front are different.
