本文主要内容是关于单相PWM逆变器的输出电压波形控制技术。好的输出波形 包含两个方面的要求：稳态精度高和动态响应快。本文围绕这两点，分析了重复控制 技术和双环控制技术，并进行了一系列仿真和实验。 (The output waveform correction technology of single-phase PWM inverter is studied in this dissertation.High quality waveform has two characteristics.It has not only nice static characteristic but also well dynamic response.Aiming at these characteristics, repetitive control technology and dual-loop control technology is analyzed.Both these control scheme are verified by simulation and experiment. )

由WAVELAB提供的计算连续小波变换,包括求小波脊的MATLAB程序工具箱.(WaveLab calculation provided by the continuous wavelet transform, including the seeking of wavelet ridge Toolbox MATLAB procedures.)

shapefile数据，全国范围四级河流数据(river data shapefile)

在MTI抑制杂波部分可能用到的原理，对应的MATLAB实例。对比单延迟对消器与双延迟对消器幅度响应。(the comparison between amplitude response of single canceler and double canceler)

一个猜单词游戏，由计算机或一方给出一个单词，另一方根据单词的个数猜出单词。-guess a word game by a computer or one of a word is given, the other party under the words to guess the number of words.

说明：  铁道车辆17自由度经典横向动力学计算程序代码。(Code of 17 DOF classical lateral dynamics calculation program for railway vehicles.)

VB6实现图片旋转操作，类似PhotoShop中的旋转功能，可进行图片的360度、270度、90度旋转，右侧为结果区，左侧图像可出每一步旋转后的效果，比较简单的VB图像操作例子。

说明：  该程序实现的是用标准卡尔曼和扩展卡尔曼滤波算法，对空中观测目标进行跟踪(The program is to use standard kalman and extended kalman filtering algorithm to track the air observation target)

说明：  实现的多线程多任务下载，采用文件切块，多线程分块下载，再拼接(Multi-threaded and multi-task download is realized. File is cut into blocks, multi-threaded is downloaded in blocks, and then spliced.)

简洁绿色的漂亮网站菜单，一个纯CSS代码实现的绿色导航栏效果，无任何JS代码，菜单修饰方面，只是用了一张渐变的背景图片，用时候把图片上传到服务器上，然后修改菜单文字和链接就可放在你的网站里了。
