中文摘要：

该文分别研究了在三种极限情况下费米超流气体在幺正极限区域的非线性Ramsey干涉图样的频率与系统参数之间的关系，研究发现费米子间的相互作用以及双势阱间最低能量差对干涉图样的角频率有显著的影响．通过数值模拟和理论分析，得到了干涉图样的角频率和系统参数之间的关系，发现数值和解析结果符合得很好．

英文摘要：

We investigate the relationships between the nonlinear Ramsey interference pattern of the angular frequency and system parame- ters of fermi superfluid gase in unitarity regime in three limited cases. We find that the interaction between fermions and the difference in energy between double-well potentials have a significant influence on the angular frequency of the interference pattern. Through numerical simulation and theoretical analysis, the relationship between angular frequency of the interference pattern and the system parameters is given, and the numerical simulations and theoretical analyses are in good agreement.
