摘　　要：该文研究了中性束注入系统中高压传输线部分电容的求解问题;根据传输线多层同轴导电壳的结构特点,利用多重镜像法确定与平行导线相应的一系列的镜像线电荷,求解的问题变为由一系列平行线电荷构成的电场问题,传输线的部分电容则通过各导体间的电位系数来求得;这一方法避免了直接求解的困难以及大量数值计算等问题。This paper deals with the partial capacitance calculation of the high voltage transmission line for the neutral beam injectors. According to the geometry of the transmission line with multilayer and coaxial conductor shell,a series of image charges relating to the parallel conductor can be found by using the multiple image method. The problem is converted into solving the electric field of the parallel line charges. The partial capacitance can be obtained by calculating the coefficient of potential among the conductors. This method can avoid the difficulties of the complex mathematical operation in the analytical method and a large amount of calculation in the numerical method.
