The following are main contents studied: A finite element method for Navier-Stokes equation with ALE formulation is considered and by combined with theNewmark method of numerical intergration a pressure correction scheme is obtained for the solution of the FE formulation of N-S equation. Because the incompressibility condition can be satisfied approximately in this scheme, the interpolation functions of elements can be equalorder for the velocity field and pressure field. In the ALE formulation the fluid-solid interaction analysis became a three-field coupling problem of the fluid field, the solid field and the fluid dynamic mesh. The properties and charactiristices of this three-field coupling problem are deeply discussed.

研究的主要内容有：主容器中流体大晃动是一种强非线性问题，文中研究了求解ALE描述的粘性流体N-S方程的有限元方法，以有利于大晃动自由液面的跟踪和流体大晃动中非线性现象的描述；并结合Newmark数值积分法推出了求解ALE型N-S方程的压力修正解法，由于这种解法可以近似满足不可压条件，因此可以采用速度场和压力场等阶插值的有限元离散格式，从而较好地解决了普遍采用的不等阶插值解法中，速度场和压力场数值精度不一致、程序编制不便等的不足。

Especially for complicated multicomponent distillation processes, such as three-phase distillations in this work, the equilibrium model will lead to a significant error in the distillation modelling.

实际精馏过程往往很难真正达到汽液平衡状态，因此Murphree板效率和等板高度概念常用于修正平衡模型计算中的非理想特性。

Compared with traditional method by solving a Jacobi matrix, calculating account is greatly decreased because only displacement and center of buoyancy need computing while those elements of waterline plane are not required.d Based on the research mentioned above, the paper presents the computer programmes of compartment definition, free surface effection, and some modules of the programme of the intact and damaged stability calculation.

与传统的拉格朗日乘子法相比，该优化方法公式推导简单，而且每次迭代只需计算水线面以下的排水体积和浮心坐标，不需计算水线面上的面积、漂心、惯性矩等要素，计算方法直接简便。 4在以上理论研究的基础上，开发了舱室定义，自由液面修正的计算机软件；编制了船舶完整、破损状态下的浮态、稳性计算的部分模块。
