1·As wavelet module maxima occur at peaks of signal, the pretreatment removes power frequency periodic components from electric signal and thus avoids misjudgments of fault.
通过预处理滤除工频周期分量，消除了小波变换在信号峰值处的模极大值，从而避免了对故障的误判。
2·To find out the singularity of the high coefficients of fault signal, the paper adopts the method of searching modulus maxima and realizes the precise rangefinder fault.
本文采用搜索模极大值的方法，进而实现故障的精确测距。
3·In fact, both came first, let's say a Maxima.
其实，无论是先假设一个极大值。
