频域内低通滤波实现图像平滑，程序原代码来自书籍，《计算机图像处理与识别技术》，作者王耀南等(frequency low pass filter)

其中的相应程序为实现解决非线性方程组的相应的方法，程序测试正确。(Corresponding procedures for the realization of the appropriate method to solve unlinear equations, the correct program testing.)

Tous les fabricants de variateurs de vitesse, qu’ils soient industriels ou bien distributeurs de matériel à usage pédagogique proposent des variateurs pour machine asynchrone. Historiquement, sont apparus sur le marché des variateurs dits à « U/f = constante » et plus récemment les variateurs à contrô le vectoriel de flux avec ou sans capteur.

利用三电平中心削波自相关法实现清、浊音判定，并提取一段话音的基频参数，绘制基频曲线，并将该参数曲线合并到前面提取的短时过零率和短时能量参数曲线图中(Using a three-level center clipping from the relevant law to achieve clear, voiced determination, and extract some of the fundamental parameters of the voice, drawing the fundamental frequency curve and merge the parametric curve to the front of the extraction rate and the short-term zero short-term energy parameters graph)

多自由度有阻尼系统的MATLAB求解代码，输入刚度，阻尼，平衡方程，自动计算结构阻尼频率和振型。(The MATLAB solution code of the damping system with multiple degrees of freedom is used to enter the stiffness, damping and equilibrium equations, and the damping frequency and vibration mode of the structure are automatically calculated.)

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)
