摘　　要：利用缀饰态理论研究了由分子和原子组成的混合共振系统中分子和原子之间的碰撞能量转移过程 结果发现 :在单模强激光场作用下 ,该混合共振系统由于发生了碰撞能量转移 ,而使得粒子在相应能级上产生重新布居 ,并在一定条件下呈现出量子干涉增强效应 ,导致了不同缀饰态能级之间出现交叠区 这一结果与现有实验报导相符 。The dressed state theory is utilized to study the process of the colliding energy transformation between the molecule and the atom within the mixing resonant system that is made up of molecules and atoms. It is discovered that since a colliding energy transformation is produced within the mixing resonant system, it makes particle re distributing in the relevant energy level and showing itself the effect of quantum interference strengthening in certain conditions. The result caused the appearance of the superposition area between one dressed state energy level and others. The result obtained in this paper is correspondence with experimental results reported recently and gives a new theoretical method for studying the effect of the quantum interference strengthening of the multi energy level system.
