此程序详细分析了LORENZ，利用GP算法进行了分析，其程序算法较快，有待继续改进(A detailed analysis of this process LORENZ, the use of GP algorithm is analyzed, the program algorithm faster, be to continue to improve)

matlab中meshgrid命令的详解，以及plot3、mesh、surf、surfc、surfl、waterfall等命令的用法(The explanation of meshgrid command in matlab, and the usage of plot3, mesh, surf, surfc, surfl, waterfall and other commands)

学习并找到降噪方法，对语音信号背景噪声做处理，使得声音更清晰。(The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.)
