基于轴对称四边形薄导体模型的电阻估算法

摘要

In this paper,a method of using axisymmetric thin conductor model as an equivalent to estimate corner resistance of an irregular shaped conductor is discussed. Starting from theoretical analysis,this paper demonstrates thatresistances between the opposite sides of all kinds of quadrilateral thin conductors are equal to their square re-sistances. Based on this conclusion,an estimation of resistance of a thin conductor which utilizes the approximate division is proposed. For instance,the method can be used to estimate resistance of an L-shaped thin conductor, and the effectiveness and accuracy of the method is analyzed and discussed when estimating.%本文提出一种利用轴对称薄片导体模型近似等效处理不规则的薄片导体转角电阻的估算方法。首先从理论出发，论证了所有轴对称的四边形薄片导体，其对边之间的电阻等于其方阻。以该结论为依据，得到了一种以近似划分为手段的薄片电阻估算法。作为实例，将该方法应用于L型薄片电阻的估算，并对这种估算的有效性和精确性进行了分析和讨论。
