ransac直线拟合：使用ransac方法剔除不好的点，留下好的点做直线拟合，这样拟合出的直线更符合实际，因为没有了错误数据的参与。(ransac linear fitting: Use ransac methods eliminate the bad points, making a good point to make fitting a straight line, so that the fitted straight line is more realistic, because there is no involvement of erroneous data.)

DFP法求优化问题的C++源代码，经测试，该程序运行正常，得到了预期的结果。(DFP method for the optimization of C++ source code, tested, the program works correctly to get the desired results.)

多相流cfd程序，用fortran实现，有多流体和dem计算功能，当然还有其它更多功能(MFiX is a general-purpose computer code developed at the National Energy Technology Laboratory (NETL) for describing the hydrodynamics, heat transfer and chemical reactions in fluid-solids systems. It has been used for describing bubbling and circulating fluidized beds and spouted beds. MFiX calculations give transient data on the three-dimensional distribution of pressure, velocity, temperature, and species mass fractions. MFiX code is based on a generally accepted set of multiphase flow equations. The code is used as a "test-stand" for testing and developing multiphase flow constitutive equations.)

实现了粒子滤波算法代码，供大家参考学习。(Particle filter algorithm to achieve the code for your reference study.)

可用于层次分析法比较评价，主函数输入初始矩阵，调用层次分析函数(It can be used for comparative evaluation of analytic hierarchy process. The main function input the initial matrix and call the analytic hierarchy process function.)

说明：  本程序是采用FDTD算法结合PML吸收边界，对对称三层平板光波导的模式场仿真(This program uses FDTD algorithm and PML absorbing boundary to simulate the mode field of symmetrical three-layer planar optical waveguide.)

说明：  微电网能量平衡的基本任务是指在一定的控制策略下，使微电网中的各分布式电源及储能装置的输出功率满足微电网的负荷需求，保证微电网的安全稳定，实现微电网的经济优化运行。(The basic task of micro grid energy balance is to make the output power of each distributed power source and energy storage device in micro grid meet the load demand of micro grid under certain control strategy, ensure the safety and stability of micro grid, and realize the economic and optimal operation of micro grid.)
