【MATLAB GUI设计学习手记】源代码 数据 罗飞大哥的作品 本书由浅入深、循序渐进地介绍了matlab gui设计的基础知识，旨在使读者在较短时间内掌握gui设计的精要所在。. 本书首先介绍了gui设计的预备知识，然后详细介绍了gui对象的属性以及两种建立gui的方法：采用函数建立和采用guide建立。在介绍了gui设计基础知识的基础上，深入讲解了activex控件、定时器、串口及mcc编译的相关知识。书中穿插了大量的图表，直观、简要地列出了相关知识点。对于一些重要、难懂的知识点，配以大量的典型例题，方便读者边学边练，加强理解。最后，书中给出了3个典型的综合实例，供读者研究学习。.. 本书适合需要短时间内迅速掌握matlab gui设计的初学者使用，也可作为相关专业师生、相关工程开发人员的参考手册。... ([MATLAB GUI design learning Notes] source code, Luo Fei works of Big Brother The progressive approach of the book, step by step the basics of Matlab gui design, designed to enable the reader to grasp the essence of the gui design where in a relatively short time. . The book begins prior knowledge of the gui design, and then details the gui object properties and methods: two ways to create gui with function to create and adopted to guide the establishment. Describes the design of basic knowledge in gui basis, in-depth to explain the activex control, timer, serial port, and mcc compiled knowledge The book, interspersed with a large number of charts, intuitive, brief list of related knowledge. For some important, difficult to understand the knowledge, together with a large number of typical example, the convenience of the reader to learn while training, to enhance understanding. Finally, the book gives three typical instance, for readers learn. .. Book is suitable for the need for a )

小波变换进行变速箱故障诊断 首先将s1和s2信号时域谱（s1代表维修前的振动信号，s2代表维修后的振动信号），画出来进行对比，会发现s1信号的振动幅值会比较高；然后对s1和s2分别进行小波分解并画出各层的时域谱，只对比s1和s2分后的最高时域谱，s2更加的具有周期性，且幅值较小，s2周期性不够明显，且振动过于密集。分析完时域谱后开始分析频谱，首先对原信号s1和s2fft转换，得到频谱图，如图，然后再对小波分析后高频部分进行fft转换，做出频谱图。对比后我们发现，在f 2375HZ出（也就是齿轮的啮合频率），s1信号频谱幅值会有急剧的升高，然后，其谐波的幅值也会增大。所以可以推断出该维修前的增速箱的齿轮可能出现问题。(Gearbox fault diagnosis based on wavelet transform s1 and s2 first time domain signal spectrum (s1 behalf of the vibration signal before maintenance, vibration signal s2 representative of repaired), drawn comparison, you will find a signal s1 vibration amplitude will be higher then s1 and s2 respectively wavelet decomposition and draw the layers of time-domain spectrum to only a maximum time domain spectroscopy s1 and s2 points after, s2 is more cyclical and smaller magnitude, s2 cyclical enough obviously, and the vibration is too dense. End domain spectral analysis after the beginning of the spectrum analysis, the first of the original signal s1 and s2fft conversion to give the spectrum, as shown, and then after the high frequency part of wavelet analysis fft transformation to make spectrum. We found that after the comparison, at f 2375HZ out (i.e. the gear mesh frequency), there will be a sharp increase in the amplitude spectrum of the signal s1, and then, the amplitude of the ha)
