振荡器仿真程序，matlab实现，通过改变相位参数振荡器来产生不同曲线(The simulation program of oscillator is realized by matlab. Different curves are generated by changing the phase parameter oscillator.)

来自百度指数，表格定时切换代码，有缓冲效果，经常访问百度指数的朋友一定见过，非常漂亮，兼容性不错，而代码也比较简洁，喜欢的朋友拿去用吧。(Underline two level enterprise website navigation menu is a jQuery based mouse slide to menu bar display.)

C#制作透明的不规则窗体，虽然不常用这种风格的窗体，但是肯定有能用得上的时候，特别是在一些大型的软件项目中，不规则窗口的需求也是有的。

PQ分解法，有些还需要改进，该程序所对应的例子是东南大学陈珩编的《电力系统稳态分析（第二版）》的例4-5-PQ decomposition, some also needs to be improved, The procedure corresponding to the example of Southeast University, Chen Heng addendum to the "steady-state power system analysis (second edition)" 4-5 cases

直接数字式频率合成器DDS设计、Verilog。 产生的信号可以是正弦波或方波、三角波、锯齿波等，自选。 采用DDS技术，将所需生成的波形写入ROM中，按照相位累加原理合成任意波形。 此方案得到的波形稳定，精度高，产生波形频率范围大，容易产生高频。 本实验在设计的模块中，包含以下功能： （1）通过 freq 信号输入需要的频率的值； （2）通过 wave_sel 信号选择所需的波形； （3）通过 amp_adj 信号选择波形放大的倍数。(DDS design of direct digital frequency synthesizer, Verilog. The generated signal can be sinusoidal or square wave, triangular wave, sawtooth wave and so on, optional. By using DDS technology, the required waveforms are written into ROM, and arbitrary waveforms are synthesized according to the principle of phase accumulation. The waveform obtained by this scheme is stable, accurate and easy to generate high frequency waveform. This experiment includes the following functions in the designed module: (1) Input the required frequency value through freq signal; (2) Choosing the required waveform by wave_sel signal; (3) Select the multiplier of waveform amplification by amp_adj signal.)
