摘　　要：为计算航天器上两个密封舱内存在压差时相互进行压力平衡所需的平衡时间,通过压力平衡过程的分析,建立了近似的数学模型,进行了分析计算,并通过容积缩比方法对计算结果进行了试验验证,得到了满意的结果,不仅能达到节约成本和时间的目的,更具有普遍性。An analytic model was established based on the research of pressure balancing procedure while existing pressure difference between two sealed cabins to calculate the pressure balance time. In addition, the calculated results were proved by the test validation of scaling cubage. And the results is satisfactory which can save costs and time with universality.
