first_order_differ---solve

三相潮流计算，使用的是牛顿拉弗逊方法。迭代较快。是解决潮流的较有效的方法。(Three-phase power flow calculation, using Newton' s method Laffer Johnson. Iterate rapidly. The trend is to solve the more effective method.)

roe格式对多种不同初始条件黎曼问题的计算。(the document solve the riemann problem with roe method.)

说明：  克里金、反距离插值算法_栅格图等值线填充等(Kriging, inverse distance interpolation algorithm _ isogram filled grid map, etc.)

用于计算学分绩,是大学实行学分制后比较实用的一个软件(used in the calculation of the credit performance of college credit system after a more practical software)
