刀具磨损的研究方法很多，本文针对近些年发展的声发射技术( AE) 在监测刀具磨损上的应用，采用理论分析和现场试验的方法进行可行性分析和验证，结果表明: 在考察的几个影响声发射信号强度的因素之中，刀具主切削刃后刀面磨损量对其影响最为显著-Tool wear a lot of research methods, this paper developed in recent years for the acoustic emission technique (AE) monitoring tool w

基于chebyshev的水声信号分析，实现串口的数据采集，时间序列数据分析中的梅林变换工具。- Based chebyshev underwater acoustic signal analysis, Achieve serial data acquisition, Time series data analysis Mellin transform tool.

The wavelet denoising is a useful tool for various applications of image processing and acoustic signal processing for noise reduction.
