用惠更斯原理研究光和原子相互作用

基于惠更斯原理和光在吸收介质中传播规律，研究了光和原子相互作用。用光在吸收介质内传播时的振幅表达式，得出了波面子波的表达式，根据子波振幅的变化和原子吸收光子间关系，得到了原子吸收光子的表达式。根据玻尔的原子结构模型，给出了原子吸收光子的微观解释。证实了量子态不可删除和不可克隆定理，解释了费曼提出的超光速和时间倒行现象。依据光增益是原子系综受激辐射的事实，重新解释了光增益机制。

Application of Huygens’Principle in Analyzing Light-atom Interaction

Based on the Huygens’ principle and the propagating process of light in an absorbing substance, we re-search the light-atom interaction. Considering the amplitude change of the light in the absorbing substance,the expres-sion of a wavelet on a wavefront is obtained. From the relation between the wavelet amplitude change and the atom absorption, the expression of atomic photon absorption is derived. Combing Bohr’s atomic model we provide a micro explanation about the atom absorbing a photon. The quantum state undeletable and no-cloning theorems are proven. The quantum superluminality and time reversal effects proposed by Feynman are explained. According to the fact that optical gain comes from the stimulated emission of an atomic ensemble,the mechanism of optical gain is reinterpreted.
