多径时变信道建模仿真，利用matlab产生单频信号与数字信号经过多径时变信道后的输出信号波(Time-varying multipath channel modeling and simulation, using matlab generate a single frequency signal and digital signal through the multipath time-varying channel output signal after the wave)

数字图像阀值分割各种方法 最大熵 OTSU 双峰法 迭代法 分水岭算法 (Digital image threshold segmentation methods maximum entropy OTSU method of bimodal iterative method of watershed algorithm)

5节点潮流计算，牛顿拉夫逊，如果需要多节点的话，自行改设参数(5-bus power flow calculation, Newton Raphson, if you need multi-node, then re-established parameters of their own)

等倾干涉（由薄膜产生的干涉。薄膜可以是透明固体、液体或由两块玻璃所夹的气体薄层。入射光经薄膜上表面反射后得第一束光，折射光经薄膜下表面反射，又经上表面折射后得第二束光，这两束光在薄膜的同侧，由同一入射振动分出，是相干光，属分振幅干涉）(Isoclinal interference)
