电火花加工；间隙电压/电流；小波分析；模极大值算法摘要：根据非导电工程陶瓷电火花加工间隙信号的特点，采用小波模极大值法对间隙电压/电流信号进行去噪处理。通过比较Maxihat小波、Meyer小波、Daubechies小波和Gauss小波等不同小波函数的去噪效果，找出了适合于电火花加工间隙电压/电流信号去噪的小波函数--Gauss小波，并确定了拟合尺度空间[-5，+1]和归一化阈值区间[0.1，0.3]。

Compaered the differernt denoising result of different wavelet function, Maxihat wavelet, Meyer wavelet, Daubechies wavelet and Gaussian wavelet, the fitting wavelet function, Gaussian wavelet which used to denoising the EDM Gaps voltage/current signal was found out, and the fitting scales space [-5,+1] and the normalized threshold value interval [0.1,0.3] was determined.
