摘　　要：研究自旋相反的两成份费米原子-分子耦合系统中,背景粒子s波散射对分子形成与分解的影响。这种粒子间的相互作用在以分子形式存在为主的演化阶段影响明显,其中排斥势散射有利于分子的形成。分子场在系统演化过程中会出现亚泊松(Sub-Poisson)统计分布。The influence of the s-wave scattering of background particles on the association or disassociation of molecules in a system composing of two species Fermi atoms with opposite spin and molecules is studied. This influence becomes evidence in the period of evolution when most of the particles in the system are molecules, where the scattering with repulsive potential is propitious to the formation of molecules. Sub-Poisson statistical distribution of the molecule field is observed.
