摘要
由电动力学知识,运用热力学关系式导出了总静电场能量的一个普遍公式,并由此得出真空中的总静电场能公式及无损耗电介质中的总电场能公式.
A general formula of the total electrostatic field energy is derived from the thermodynamic expression and electrodynamics knowledge.Then the formulas of the total electrostatic field energy in vacuum and loss-free dielectric are obtained respectively.
