用导体系的部分电容理论辨析电容的定义

摘要

分析了目前教材和文献中关于电容定义的两点分歧,所得结论对电容有关内容的教学具有较大的参考价值。分析中使用的是导体系的部分电容理论,分析过程表明该理论是分析电容有关问题的一个有力而简捷的工具。%Two differences about the definition of the capacitance in present books and papers are analyzed,and the fruits have much reference value for the teaching of the contents about the capacitance.The theory that is used as the theory of the partition capacitance of the system of conductors,and the analytic process indicates that the theory is powerful and simple for the analysis of the problems about the capacitance.
