摘　　要：有限结构尺寸电容器电容的计算在电磁学及电工技术学科中既有理论意义又有工程实际应用参考价值。本文以同轴圆柱电容器电容的计算为例 ,通过将其作为典型的静电场边值问题进行处理 ,从而得到了可适用于对具有任意极板半径与其纵向尺度之比的圆柱电容器电容的解析计算关系 ,数值计算结果与有关理论近似分析的高度一致性 ,表明了所建立的分析模型的有效性。In the fields of electromagnetics and electrotechnics, the calculation of the capacitance of capacitors that have finite structure dimensions have both theory importance and engineering practice worthiness. As an example, the capacitance of the cylindrical capacitor has been studied, in which the method of the solution of electrostatic boundary value problems is used to calculate the capacitance of the cylindrical capacitor, the analytical formula has been found which can be used to compute the capacitance of the cylindrical capacitor with arbitrary ratio of its plate radius to the lognitudinal size. The consistent of the numerical value results with that of the theorys approximations indicate that the analyzing mode is effective.
