在周期调制场下，通过对双势阱中费米子数目及相互作用参数的调节，研究了该系统中玻色子的自俘获现象．研究发现，系统中费米子数目及相互作用参数都会影响玻色子的自俘获现象，并且随着相互作用及粒子数目的变化，玻色子的自俘获发生临界现象．

英文摘要：

In this paper, we study the self-trapping of a Bose-Fermi mixture in a periodic modulation field by adjusting fermionic number and interaction parameter in a double-well potential. We find that the self-trapping of bosons can be affected by interatomic self-interactionand interspecific interaction parameter. Moreover, we notice that the self-trapping of bosons gives rise to a critical phenomenon with the variation of interaction strength and fermionic number.
