摘要
指出在一般教学参考书中给出的静电场互作用能公式 ,仅仅是电势能公式 .两个带电物体间的相互作用能 ,除了势能以外 ,还应包括由于相互极化导致物体极化状态改变所作的功和外电源提供的能量 .
It is pointed out that the interaction energy formulas given by some textbooks and reference books is only the potential energy formulas.Besides the potential energy,the interaction energy between two charged ploarizable objectes should include the work done in changing polarizationstate of the objects due to inter-polarization and the energy supplied from the external source.A general formulas of the interaction energy between two charged objects is obtained.
