摘　　要：声发射技术作为一种成熟的无损检测手段,对声发射信号的分析有重要意义。针对大量的声发射信号撞击文件,单独利用C#或MATLAB语言都无法快速进行声发射信号特征参数分析。通过研究C#与MATLAB混合编程的常用技术,详细分析.NET程序集调用MATLAB函数编写C#窗体应用程序的方法,利用上述方法实现了对大量声发射信号撞击的特征参数提取和分析。通过程序实例,证明了所提方法能够降低声发射信号处理分析算法的实现难度,提高声发射信号处理分析的效率,同时也验证了上述方法的可行性。Acoustic emission technology, as a mature non-destructive testing method, is of great significance to the analysis of acoustic emission signals.For a large number of acoustic emission signal hits, using C# or MATLAB language alone can not quickly analyze the parameters of acoustic emission signals.By studying common techniques of mixed programming of C# and MATLAB, the method of compiling C# window application by calling MATLAB function in.NET assembly was analyzed in detail, and the parameter extraction and analysis of a large number of acoustic emission signal hits were realized by this method.Through a program example, it is proved that the method can reduce the implementation difficulty of the acoustic emission signal processing and analysis algorithm, improve the efficiency of the acoustic emission signal processing and analysis, and also verify the feasibility of the method.
