摘　　要：运用电子云导体模型分析了光与真空中自由电子之间相互作用,分析结果与已有理论一致.结合电子云导体模型对下列情况的分析:氮分子在飞秒强激光作用下的电离、X射线与分子中电子的作用等,可以说明光与电子之间确实存在电磁感应相互作用,光与电子间能量交换的根源之一是它们之间的电磁感应相互作用.According to the electron-cloud-conductor model,there should exist interaction of electromagnetic induction between light and electron when they meet,and this interaction may result in the energy exchange between them.Energy exchange between light and free electron in vacuum is analyzed with the model,and the result consists with that of the existing theory.The model can also be used to explain the experimental result of ionization rate of N2 molecules by short laser pulses and the behavior of ionization of molecules by X-ray.It is concluded that one of the root causes for energy exchange between light and an electron is electromagnetic induction between them.
