摘　　要：近似方法是科学研究中的一种重要方法。以圆截锥导体两截面间的电阻值的计算为例,分别用平面等势面近似和扁旋转椭球壳近似两种方法求出电阻值。分析结果显示,阶梯连接面处具有附加电阻效应。Approximate method is an important method in scientific research. The calculate of the resistance of a frustum of a cone is performed as an example. Equipotential surface approximate method and spin ellipsoid shell approximate method are used to calculate the resistance. The results show that stair cormeets could result to additional resistance.
