二极管实现混频的matlab验证，有注释说明，便于理解二极管混频(Matlab verification of diode realization mixing)

说明：  本软件用于计算不同边界条件下均匀直梁横向、纵向前三阶固有频率。(The software is used to calculate the first three natural frequencies of the transverse and longitudinal direction of a uniform straight beam under different boundary conditions.)

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

1、目标速度引起的失真，时间膨胀因子10%、chirp中心频率偏移5%。 2、超高速运动对脉冲压缩的影响，多普勒频移补偿(Distortion caused by target speed, time dilation factor 10%, and chirp center frequency offset 5%. Effects of ultra high speed motion on pulse compression and Doppler frequency shift compensation)

旅行社管理系统,VB.Net开发。 功能齐全,代码注释详细.(Travel Agency Management System, VB.Net development. A full-featured, code comments in detail.)

风力发电机mppt控制程序，基于扰动观察法(The program of PWSM mppt)

说明：  在分隔器窗格中切换视图 (switch view in separators pane)

用于计算多普勒频移的函数，MATLAB语言，挺好用。(The function for calculating Doppler frequency shift, MATLAB language, is very useful.)

为了感谢惠俊英老师的谆谆教诲，再为好奇诸君奉上水声物理--海洋传播声场模拟的一份武林秘籍--海洋传播声场抛物方程解算方法--RAM！ 当好奇诸君阅毕此卷，再对照轻松跑完作业，即入门 RAM！ RAM 与 AcousticsToolbox 遵照 GNU 公共许可证进行分发。感谢Michael D.
