摘　　要：以部分管理表面张力贮箱的管理舱为研究对象,利用三维气液平衡界面计算程序Surface Evolver,在无重力和微重力且几何边界条件比较复杂的环境下对管理舱内的气液平衡界面进行数值模拟;计算结果与已经应用卫星的理论计算完全吻合。Management cabin of a surface tension tank is used as an example in this study. By using Surface Evolver, a computer model being developed by the Geometry Supercomputer Project, fully three-dimensional gas-liquid equilibrium interfaces can be calculated under micro gravity. The method presented can be valuable for the physical design of propellant maganement device （PMD）.
