同轴不连续性等效网络中变分电容上、下限值的物理实质

摘要

The lower bound to the equivalent variational capacitance of a coaxial step discontinuity was solved with Functional Approximation Methods;the identity between the upper bound and lower bound to the equivalent networks' variational capacitances was proved for several common coaxial discontinuities, basing upon the identity essence of the upper bound and lower bound to the variational capacitance was obtained from the standpoint of eigen mode function.%应用泛函近似方法求解了一类同轴阶梯不连续性结构等效变分电容下限值；证明了几类常见同轴不连续性等效网络中变分电容上、下限值的同一性,并据此从本征模式函数的角度给出了该上、下限值的物理解释.
