NET Core+EF Core实例,自己使用了,很好,没有问题(NET Core+ EF Core instance, oneself use, is very good, no problem)

这是最近本人用组态王做得实验室配套双容水箱监控程序，画面清晰漂亮，欢迎大家浏览查看！(Penguin Card Oh, Rosaceae to joke to joke to see his wife thought of the film to go see his wife, playing Walker to play with bottle opener Will and weapons 2)

PMSM控制系统采用速度电流双闭环矢量控制调速系统，即控制系统中有速度调节器和电流调节器。(PMSM control system adopts speed and current double closed-loop vector control speed regulation system, that is, speed regulator and current regulator are included in the control system.)

电力系统静态稳定分析，小扰动分析法，简单算法(Static stability analysis of power system small disturbance analysis, a simple algorithm)

此程序的功能是，采用细胞自动机方法，进你火灾模拟。(This program' s function is, using cellular automata method, into your fire simulation.)

该程序主要是用于水准测量中水准数据的平差处理，精度较用平差易软件高(The procedure is mainly used for leveling leveling data in the adjustment processing, precision adjustment easy software)

世界领先的数字近景摄影测量系统软件2007版，绝对值得收藏。(The world s leading digital close-range photogrammetry system software, 2007 edition, is worth collection.)

这是关于七参数转换的代码，他的转换精度高，另外附有原始数据(Seven parameter transformation)

牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)
