电容器电量重新分配过程中静电能的转化及其计算

Transform and Calculation of the Energy of Static Electricity in the Course of Redistribution of the Quantity of Electric Charge of the Condenser

电容器电量重新分配过程中损失的静电能一般转换为焦尔热和电磁辐射能,电路的似稳条件是否满足以及研究的目的决定了电磁辐射能是否为可忽略不计的小量,也决定了对电路的计算是采用基尔霍夫定律还是麦克斯韦电磁场方程组.

The decreased energy of static electricity generlly changes the Joule'heat and the energy of electromagnetic radiation in the course of redistribution of the quantity of electric charge of the condenser,the seemingly stable condition of the circuit which is satisfied or not and the goal of the research decides whether the energy of electromagnetic radiation is a minor quantity which may be neglected ,and also decides the research of the circuit is employed by the G.kirchhoff law or by the group of equation of Maxwell.
