求传递函数的一般格式，通过该程序，我们基本上能写出求任意的传递函数的式子(The general format of the transfer function of demand。Through this program, we can write the formula basically seeking arbitrary transfer function)

this is a matlab code with a gui that designs a shaft depending on the type of material needed the loads acting on it and the factor of safety

经验模态分解，依据数据自身的时间尺度特征来进行信号分解，给出本征函数。(Empirical mode decomposition, based on the data itself characteristic time scale for signal decomposition, given the intrinsic function.)

说明：  既可以用于高压输电网的潮流解算，又可以用于低压配电网的潮流解算，还可以同时解算输电网 加配电网的混合潮流问题,程序为PQ 分解法.(Both the trend for high-voltage transmission grid solver, but also the trend for low voltage distribution network solver, solver can also increase with the power transmission grid hybrid power flow problem, the program for the PQ decomposition.)

使用matlab写了一个很有意思的程序 大家看看作为参考(Use matlab write a very interesting program we look at as a reference)

Photonic crystals are attractive optical materials for controlling and manipulating the flow of light. One dimensional photonic crystals are already in widespread use in the form of thin-film optics with applications ranging from low and high reflection coatings on lenses and mirrors to colour changing paints and inks. Higher dimensional photonic crystals are of great interest for both fundamental and applied research, and the two dimensional ones are beginning to find commercial applications. The first commercial products involving two-dimensionally periodic photonic crystals are already available in the form of photonic-crystal fibers, which use a microscale structure to confine light with radically different characteristics compared to conventional optical fiber for applications in nonlinear devices and guiding exotic wavelengths. The three-dimensional counterparts are still far from commercialization but may offer additional features such as optical nonlinearity require
