DIgSILENT自带的例子，分享一下。(DIgSILENT comes with examples to share.)

说明：  基于MATLAB的飞机六自由度模型，可以说具有很强的实用性和普适性(The six-degree-of-freedom model of aircraft based on MATLAB can be said to have strong practicability and universality.)

利用LABview软件的频谱分析功能实现使用FFT分析信号幅度谱和相位谱，(Analysis of Signal Amplitude Spectrum and Phase Spectrum by FFT)

说明：  根据股票的日收益率 计算该股票的在险价值VAR 并对不同的置信度进行计算 并附带作图功能(Value at Risk (VAR) of the stock is calculated based on the daily return of the stock, and different confidence levels are calculated with the function of drawing.)

说明：  The power electronic drive controls the rate of induction motor by V/F method.

说明：  simulink的小车lqr控制程序，可以控制定点平衡，原程序。(lqr )

用二维装箱算法实现矩形地块放置优化问题，使用遗传算法优化(Two dimensional packing algorithm for rectangular block placement optimization)

地震子波的编程，并将子波进行褶积，判断不同频率下的分辨率(Seismic Wavelet Programming and Wavelet Convolution to Judge Resolution at Different Frequencies)

说明：  学习VBA for Acad，AUTOCAD二次开发，提高设计制图效率，定制适合自己工作的插件(Learn VBA for Act, AUTOCAD secondary development, improve design and graphics efficiency, customize plug-ins suitable for their own work)

这个程序是一个个人考勤软件,它从系统时钟获取时间信息,只要上下班时按时在当日考勤栏内点击相应的栏目标题即可逐日记录下个人每天的工作时间,按月统计汇总,按年形成文件.可以随意查看过去的记录,也可把记录按月打印出来.在年汇总栏内可以选择要查看或打印的月份。( This procedure is a each one person checks attendance software, it from system clock gain time information, so long as time coming and going to work on time checks attendance in the same day in the fence to click on the corresponding column title then day after day to record takes down individual daily operating time, monthly 缁熻?姹囨? yearly forms the document Was allowed to examine at will the past the record, also might monthly print the recording Compiles in the fence in the year to be allowed to choose 鎷╄? the examination or the printing month. )
