前推回推法计算配电网潮流，已经通过验证，结果正确。同时计算出电压、电流、网损。(Calculation of forward and backward push distribution networks, has been validated, the results correctly. At the same time to calculate voltage, current, power loss.)

comsol仿真平面电磁波在自由空间传播入射一个角度 在无限电介质。该模型计算的反射和 透射系数，并比较结果到菲涅耳方程。(A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares the results to the Fresnel equations.)

说明：  为考查各种不确定性因素对系统运行的影响，需要大量地重复性潮流计算。结合概率理论形成的概率潮流计算能够充分考虑这些不确定性因素。由概率潮流计算可以得到节点电压、电流、支路潮流的均值、方差、概率密度函数等统计特性，从而更全面地反映系统运行状况。(In order to examine the impact of various uncertainties on system operation, a large number of repetitive power flow calculations are needed. The probabilistic power flow calculation based on probability theory can fully consider these uncertainties. Statistical characteristics of node voltage, current and branch power flow, such as mean, variance and probability density function, can be obtained from the calculation of probabilistic power flow, thus reflecting the operation status of the system more comprehensively.)
