说明：  DDA、Bresenham、MidBresenham画直线算法(DDA,BresenhamLine,MidBresenhamLine)

绘制B样条曲线，可以由控制点画，也有反求控制点的(Rendering B-spline curve can be controlled by the stipple, but also have control points in Reverse)

信号频谱分析 1. 观测已知方波信号、正弦波信号的频谱 分析频率为4KHz、8KHz的占空比为50 的方波信号、正弦波信号的频谱。记录所得频谱图。 观测实时模拟信号（语音）的频谱 用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图(Signal spectrum analysis 1. Observing a known square-wave signal, sine wave signal frequency spectrum analysis 4KHz, 8KHz for the 50 duty cycle square wave signal, sine wave signal frequency spectrum. The recorded frequency spectrum. Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of voice, voice saved as. Wav format. Wav file of the sub-Fourier transform analysis to make. Speech is divided into syllables, it should be sub-analysis, and practical application of digital signal processing of the FFT points is limited, generally only reach 1000 points. Fourier inverse transform IFFT, to restore the signal from the frequency domain. Draw maps and voice waveform spectrum)

DBchart 画图 进行时间等分 时间等分(dbchart )

PSCAD做的风力机模型，嵌入了3维风力特性曲线，动态调节转矩与转速。(PSCAD do wind turbine model, embedded in the 3 d wind characteristic curve, dynamic torque and rotational speed adjustment.)

电力系统两机振荡仿真分析，500kV交流线路(Two machine oscillation in power system in PSCAD.)

主要演示Python画曲线的程序，没有太大的用处，只是为了能够下载程序(The main demonstration of Python drawing curve program, not too much use, just to download the program)

又来了~~继上次之后的又一重磅出击，本程序也是图形填充(Here we go again ~ ~ Following the last after another heavy attack, the process is filled with graphics)

本程序可以在MFC中打开并显示一张图片，代码比较简单基础(Open and display a picture in MFC)

说明：  几个常用的visio模具，想用的下载来用吧(Several commonly used Visio molds. Download them if you want to use them)
