这是一个骑士问题的程式，虽然作法不是很好～有点暴力～但是跑出来还OK！-This is a knight of the program, although the practice was not very good- a little violence- but also come out OK!

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 powe

一个强大的服务程序时不时的出现，因为经常的时候我们会尝试定期做同样的事情，但有时会忘记，所以这个服务程序都是有编写的，有点像一个常规的Sql一样的作业，可以先设置执行多长时间。

猜数字小游戏。游戏规则：随机产生4个数字，由玩家输入4个不重复的数字（如：8 3 1 2）按回车后电脑给出提示，其形式为"?A?B".你所输入的四位数中，位置和数字都正确则为A，数字相同但位置不相同时为B，你只可以猜10次，若你所用的次数小于纪录保持者，则为破纪录。-small game viewing. The rules of the game : randomly generated four figures from the importation of four players not to repeat the figures (eg : 8 3 1 2) by the transport after the computer is suggested, in the form of "A B." You have entered the four-digit, location and the correct figures for A, figures but with the location is not same as B, you can only guess 10 times, if you use less than the number of records, compared with the record.
