摘　　要：基于最小动量态上的玻色-爱因斯坦凝聚(简称BEC),给出了指数吸引势场中超冷玻色原子气体的势场有效性和势阱中所装载的原子数目极限判据.此判据给出了当所装载的原子数确定时,所需要的势场强度;或势场给定时,所装载的原子数目的极限.Based on Bose-Einstein condensation at minimized momentum state, a criterion for the validity of potential and the limited atom number loaded in a power law attractive potential well for uhra-cold atom gas is deduced. The criterion gives the required potential intensity when the loaded atom number is defined, or the limited atom number when the potential intensity is decided.

关 键 词：玻色-爱因斯坦凝聚 临界温度 最小动量态
