This paper gives the further analysis of node voltage equations and its matrix form, and the methods to write out nodeequations with strong operation.
引入了结式的矩阵形表示，提出了矩阵形结式的移位变换概念，并利用其得到了结式计算的一个简便方法。

The modified scalar potential is used to reduce the order of the coupled equations in the comparison with the vector potential under the same node number.
计算量采用修正标量位，这样在同样的节点数下相对于矢量位它可以减少联立方程的阶数。
