说明：  递归，是函数实现的一个很重要的环节，很多程序中都或多或少的使用了递归函数。递归的意思就是函数自己调用自己本身，或者在自己函数调用的下级函数中调用自己。 递归之所以能实现，是因为函数的每个执行过程都在栈中有自己的形参和局部变量的拷贝，这些拷贝和函数的其他执行过程毫不相干。这种机制是当代大多数程序设计语言实现子程序结构的基础，是使得递归成为可能。(Recursion, is a function to achieve a very important part of many programs are more or less use the recursive function. Recursive mean that the function of its own call to themselves or subordinates in their own function calls a function to call their own. Recursion that can be achieved because the function of each execution in the stack has its own shape parameters and local variables of the copy, the copy and the implementation process has nothing to do other functions. This mechanism is the most modern programming language implementation subroutine structure of the foundation is to make recursion possible.)

说明：  信号的叠加、信号叠加后不超标时间的计算、fourier级数拟合(Superimposed on the signal, not excessive computing time after the signal is superimposed, fourier series fit)

LC 低通巴特沃斯无源滤波器设计 根据给出的参数值自动计算LC 取值(Butterworth passive LC low-pass filter design parameters according to the given value automatically calculated LC)

说明：  此程序中将两个离散时间信号卷积，在数字信号处理过程中很有用！(conversion)

PV_MPPT 很好的光伏最大功率跟踪控制(PV_MPPT good photovoltaic maximum power tracking control)

基于PWM的直流电机的闭环调速控制系统设计(PWM based closed loop DC motor speed control system design)

主要实现可倾瓦轴承轴承油膜压力计算，文件包括雷诺方程的差分求解的理论推导和matlab实现代码。(The main achievement tilting pad bearings film pressure calculations, including the theory of differential file solving the Reynolds equation is derived and matlab implementation code.)
