我们描述了捕获和蒸发冷却原子的部分凝聚样本的广义时间相关平均场方程。这些方程提供了一种研究可能存在的各种阶次参数以及由于凝聚原子而产生的场平均值是否存在的方法。我们的方法为我们提供了一个针对现有阶次参数的自洽方程的封闭系统。我们推导出的方程在各种限制下都可以简化为文献中的其他处理方法。我们还展示了运动方程方法如何使我们能够构建一种形式主义，该形式主义可以处理由于双环动力学而导致的这些平均场的演化。
We describe generalized time-dependent mean-field equations for partially condensed samples of trapped and evaporatively cooled atoms. These equations give a way of investigating the various order parameters that may be present as well as the existence of a mean value of the field due to condensed atoms. Our approach provides us with a closed system of self-consistent equations for the order parameters present. The equations we derive are shown to reduce to other treatments in the literature in various limits. We also show how the equation of motion method allows us to construct a formalism that can handle the evolution of these mean fields due to two-loop kinetics.
