使用Fortran实现DIF-FFT

基于simple算法的计算流体力学入门级程序。(CFD program based on Simple algorithm.)

fortran90程序，运用Runge-Kutta法数值求解常微分方程的程序，非常适用，包括源代码、一个算例和输出程序(fortran90 procedures, the use of Runge-Kutta method for numerical solution of ordinary differential equations of the process, is very applicable, including source code, a numerical example and output procedures)

一个简化的有源滤波器串联配置，提高并联型无源滤波器的滤波。(A simplified active filter in series configuration to improve the shunt passive filter filtering.)

说明：  采用电力仿真软件PSCAD建模相位同步，适合学习者参考(PSCAD phase PLL fit to beginner)

说明：  计算球体重力及重力梯度异常，已知地下球体的相关参数，即可正演该球体的重力及重力梯度(Calculation of gravity and gravity gradient anomaly of sphere)

这是大地电磁一维正演程序，只要输入电阻率和深度即可正演计算；使用的是卡尼亚视电阻率公式，有关说明已经在文件中说明。(This is a one-dimensional magnetotelluric forward the program, as long as the input resistivity and depth to forward calculation use Carney ATV resistivity formula, and instructions in the file description.)

说明：  一维transport方程利用dg方法数值模拟(Numerical simulation of one-dimensional transport equation using DG method)
