此程序是二维分数阶粘弹性声波有限差分法的正演模拟，时间导数二阶精度，空间分数阶导数2阶精度，含波长快照，未加边界，确保可运行。(This program is a two-dimensional fractional viscoelastic acoustic forward modeling of finite difference method, the time derivative second-order accuracy, space fractional order derivative 2 order accuracy, including wavelength snapshot, without borders, to ensure that can be run.)

数字转换工具，大写数字与小写数字的相互转换(Digital conversion tool, uppercase and lowercase digits digital conversion)

用C写的表达式计算器，不但可以完成四则运算，还可以处理一些函数运算，可以配合graphviz画出表达式树和计算过程。(Written using C expression calculator, not only can complete the four operations, but also can deal with a number of functions computing, you can tie in with graphviz to draw the expression tree and calculation process.)

有的科技图书会附有索引，其中列出书中重要术语出现的页码，便于读者查看。试设计一个类似的程序。输入是一个英文文本文件，输出是文件中关键字及其出现的行号的列表并按照关键字有序排列。程序运行方式：>index inputfile keys outputflie (Some books will be accompanied by technology index, which lists important terms appear in the book pages, easy to readers to view. Try to design a similar procedure. English text input is a file, the output is a file that appears in the keywords and their line numbers list and ordered according to keywords. Program run mode:> index inputfile keys outputflie)

button按下后，edit控件内容连续变化，button抬起后edit内容停止变化。自己做的例子，只以int数据为例。(button is pressed, edit control content changes continuously, button lift stops changing after edit content. Own example, an int data as an example only.)

校运动会代码（部分），使用VB编程，由学生自己开发(yundonghui)

说明：  基于QT的音乐播放器，简单易懂的QT训练小项目(Music player QT - based music player, easy to understand QT training small projects)

此程序能指导四等水准测量过程并计算相关限差，以及计算闭合差(This program will guide four leveling process and calculate the relevant limit is poor, and to calculate the closed-poor)

修改过的GH0ST界面和功能调整，增加启动FLASH(Revised GH0ST interface and functionality adjustments to increase the boot FLASH)

harmonic_3phase--3相谐波例子，自己编写！！初学者应该有一些参考价值(harmonic_3phase-- 3 phase Harmonic example, the preparation of their own! ! Beginners should be some reference value)
