说明：  1、图像显示：这个代码中制作了比较友好的图像显示功能和函数接口，非常方便客户调用，图像显示制作成控件的模式，带源代码； 2、图像显示平移以及放大缩小：在图像显示代码模块中以及将图像的拖拽、鼠标滚轮控制的放大缩小功能集成好了，提供代码接口，非常好用，可看到源代码学习； 3、文件操作模块：目前代码集成了6种文件的创建读写保存类，分别为：office中的Excel操作，IniFile的操作，LogFile的操作，Spire控件下的Excel操作，Txt文件操作，Xml文件操作(1. Image display: this code makes a friendly image display function and function interface, which is very convenient for customers to call. The image display is made into control mode with source code; 2. Image display translation and zoom in and out: in the image display code module, the image drag and zoom function controlled by mouse wheel are integrated, providing code interface, which is very easy to use and can see the source code learning; 3. File operation module: at present, the code integrates six kinds of file creation, reading, writing and saving classes, including excel operation in office, IniFile operation, logfile operation, excel operation under spire control, TXT file operation, XML file operation.)

S变换时频域滤波是一种二维的时间域—频率域的分析方法，此程序通过对信号进行时频域转换，通过分析干扰信号的时间与频率的分布范围，设计相应的滤波器进行滤波可以有效的去除干扰，又因为S变换的是无损的可逆的因此对信号没有损伤。(S transform time domain filtering is a two-dimensional time domain - frequency domain analysis method. By analyzing the time and frequency domain of the signal, by analyzing the distribution range of the time and frequency of the interference signal, the corresponding filter can be designed to remove the interference effectively, and because the S transform is nondestructive and reversible. There is no damage to the signal.)

工作流的各种资料的集合，有源码，好东西呦！-something about workflow using with c#

matlab中的基于两点平的矢量控制，控制对象是永磁同步电机。(The two-point flat vector control in matlab, the control object is a permanent magnet synchronous motor.)

说明：  AR程序设计（2），扫描图片可以出现三维模型，并操作(AR programming(2), scanning pictures can appear three-dimensional model, and operation)

中的图像可以放大和平移，还可以全屏显示。(The image can be enlarged and shifted, and can also be displayed in full screen.)

4）读取音乐信号romanza_pe.wav, 截取其前10s信号，选择适当的窗口类型和窗口宽度，显示其短时傅立叶频谱，以便能更清晰地看清谱线。说明信号频谱特点。 5）令D=5下采样音乐信号，播放其声音并显示其短时傅立叶频谱。描述并解释你所听到的声音和观察到的频谱之间的关系() Read the music signal romanza_pe.wav, intercept its first 10 s signal, select the appropriate window type and window width, display its short-time Fourier spectrum, so as to be able to see the spectrum lines more clearly. The characteristics of signal spectrum are explained. 5) let D=5 sample the music signal, play its voice and display its short-time Fu Liye spectrum. Describe and explain the relationship between the voice you hear and the observed spectrum.)
