Butterworh滤波器程序

对线性平流方程的时间和空间的前差格式、中央差分格式、后差格式(Difference of weather data )

说明：  关于雨点的散射程序，希望和有关同行探讨探讨(The scattering process on the rain, hope, and the study of peer)

PSCAD Simulation for Lines

说明：  fortran编写的一维有限差分法代码，只适合均匀步长网格，变步长也是比较好实现仅供参考(MT forward modeling,One dimensional finite difference code written by FORTRAN)

采用 Lax-Wendroff算法计算非粘Bergers方程(nonviscous Burgers equation, Lax-Wendroff method.)

solves 1d linear wave eq. by 4th order 13 point DRP scheme

电力系统仿真建模需要的模型，可以适合智能电网，分布式发电(power system modeling control smart grid stability)

计算正交各向异性材料（如木材，复合材料等）的弹塑性本构(The elastoplastic constitutive relation of orthotropic materials is calculated)

一篇论文，对研究转子动力学初学者有参考价值，题目为叶片振动影响下双盘转子-轴承系统的稳定性与分岔。(Paper, the study of rotor dynamics beginners reference value, titled double-disc rotor blade vibration under the influence- bearing system stability and bifurcation.)

自己用fortran语言编写的六脉波桥路（晶闸管换流器）触发模块，与PSCAD中自带的触发模块做过对比，验证了正确性(Fortran language they used six pulse bridge (thyristor inverter) trigger module that comes with the trigger module PSCAD done verified by comparing correctness)
