代码说明：

给出一段噪声音乐信号，用滑动平均滤波器进行处理，观察改变滑动窗口宽度对声音效果的影响。（1）读取一段噪声信号，画出未处理噪声信号的时域波形和信号频谱图；（2）在Matlab中利用滑动平均滤波器对噪声信号进行处理，得出处理后的图像；（3）改变滑动窗口的宽度，观察处理后噪声以及图像得出对效果的影响。(A piece of noise music signal is given. It is processed with a sliding average filter to observe the effect of changing the width of sliding window to the sound effect. (1) a noise signal is read and the time domain waveform and signal spectrum map of the unprocessed noise signal are drawn. (2) in Matlab, a sliding mean filter is used to process the noise signal, and the image after processing is obtained. (3) to change the width of the sliding window, to observe the noise after processing and to the effect of the image.)

感知准则函数是五十年代由Rosenblatt提出的一种自学习判别函数生成方法，Rosenblatt企图将其用于脑模型感知器，因此被称为感知准则函数。其特点是随意确定的判别函数初始值，在对样本分类训练过程中逐步修正直至最终确定。 (Perception criterion function is the 1950s proposed by Rosenblatt, a self-learning discriminant function generation method, Rosenblatt attempt for a brain model of perception, is known as the perception of the criterion function. Its characteristics are free to determine the discriminant function of the initial value, the gradual modification in the sample classification training process until finalized.)

这本书是很好的。第一次遇到转子动力学的人应该看这本书。尤其是研究有限方法的人。(This book is very good. Those who encounter rotor dynamics for the first time should read this book. Especially those who study limited methods.)
