| Abstract: | 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. |
