摘要: 任意k×n阶电阻网络等效电阻的公式研究属于科学难题,到目前为止已经获得了当k=1,2,…,5时的5种情形下的等效电阻公式,但对k≥6时的等效电阻的普适公式仅仅作为猜想给出.本文根据建立的任意k×n阶电阻网络等效电阻研究的方法,证明了k=6时的等效电阻公式的正确性,并且给出了其无穷网络的等效电阻公式,在对比验证时得到了一些新的三角恒等式.

Abstract: Study on equivalent resistance formula of any k×n-resistor netwok is a scientific problem, so far people have educed the equivalent resistance formula in the five cases that k = 1,2,… ,5. But it is only given as a conjecture for the universal formula of equivalent resistance when k ≥6. Based on the established method of the ex- isting achievements which studied equivalent resistance of any k×n resistor network, we prove the corretness of conjecture of the equivalent resistance formula when k = 6, and give the formula of the equivalent resisance of the infinite network. We obtain some new trigonometric identities when the result is compared with others.

Key words: 6×n-rectangular network, a proof of conjecture, equivalent resistance, difference equation, matrix transform, trigonometric identity
