一个计算独立回路矩阵元素的新公式

A Theoretical Formula for Calculating the Matrix Element of Independent Loop

本文从场论说给出了非线性网络中独立回路方程组形式，并将其改写成网孔方程组，求此方程组的解答，得到一个从非线性网络到线性网络的可按网孔行列式来计算独立回路矩阵元素的理论公式文中最后以实例验证了该公式的正确性.

Rewritting the independent loop's equations of non-linear network given by field theory into network hole's equations and solving them, a theoretical new formula for calculating the matrix element of independent loop by network hole's determinant in non-linear or linear network was derived.Then the correctness of the formula was illustrated.
