摘要翻译：
研究了外调制场激发玻色-爱因斯坦凝聚体拓扑相干模时Ramsey条纹的形成。当外加一系列脉冲激励场时，会出现Ramsey条纹。在Rabi和Ramsey问题中，由于系统中存在着强非线性，种群最大转移值都会发生偏移。发现Ramsey模式本身保留了地相干模和激发相干模之间积累的相对相位信息。

英文摘要：
The Ramsey fringes formation during the excitation of topological coherent modes of a Bose-Einstein condensate by an external modulating field is considered. The Ramsey fringes appear when a series of pulses of the excitation field is applied. In both Rabi and Ramsey interrogations, there is a shift of the population maximum transfer due to the strong non-linearity present in the system. It is found that the Ramsey pattern itself retains information about the accumulated relative phase between both ground and excited coherent modes.
