用对称性求解网络问题——兼谈对P.P.ong著“用短路法求网络的电阻”一文的意见

本文对文提出商榷,指出:具有对称性的电阻网络,未必都能简化成简单的串并联电路;仅利用其对称性,便可找到电路电流关于某点,或某直线,或某平面的对称分配,于是即可将复杂网络问题简化,或者将复杂网络变换成简单的串并联电路,勿须作等电位面,亦不必将所有等电位点短路,就能方便地求解。

Solving the Network Problem by Using the Symmetry

This article is going to make a suggestion to the paper②.It points out that not all the resistance network of symmetry can be changed into the simple series-parallel circuit.only using its symmetry,we can find the symmetrical distribute of the circuit current about certain point, certain straight line or certain planes.Therefor we can simplify the Complex network problem or change it into simple series-parallel circuit.without making epuipotential surface and short circuit of all the epual potential points,we can easily solve the problem.
