Based on the theorems of moment of momentum of a rigid system and the basic equations of fluid,considering the influence of the liquid sloshing,vorticity of liquid,gravitation, centrifugal and Coriolis inertial forces, and using the theory of homogeneous vorticity introduced by Pfeiffer,the boundary value problem of liquid sloshing and the differential .
以刚体系统的动量矩定理和流体运动的基本方程为基础，考虑液体晃动、涡旋、重力、离心力及Ｃｏｒｉｏｌｉｓ力等因素的影响，并运用Ｐｆｅｉｆｆｅｒ推广的关于流体均匀涡旋运动的理论，导出了液体晃动的边值问题和流固耦合旋转系统运动的联立微分方程组。
Liquefied Natural Gas(LNG) is a kind of high quality and clean energy,but many accidents have taken places since it was widely used,and stratification is the necessary condition for rollover.
液化天然气(LNG)作为一种优质洁净的能源兴起以来,发生过多起储运失稳事故,其中分层是导致涡旋的必要条件。
As the model takes no account of the consequences of boil off rate on density difference and can not interpret the acceleration of the interface's descending before rollover, the paper developed an advanced model which has 4 phases instead of 3 of the old one, and this phase dividing is more reasonable.
介绍了液化天然气涡旋问题和Ｂａｔｅｓ－Ｍｏｒｉｓｏｎ模型，并针对Ｂａｔｅｓ－Ｍｏｒｉｓｏｎ模型没有考虑蒸发率对密度差的影响、不能解释涡旋发生前分界面加速下降这一事实等缺陷，提出了改进四阶段涡旋模型。
Stratification and the subsequent rollover phenomenon are serious problems in the storage of LNG.
描述了两个典型的液化天然气涡旋事故，分析了分层和涡旋现象形成的机理，介绍了国内外提出的双向对流扩散模型、Ｂａｔｅｓ－Ｍｏｒｒｉｓｏｎ模型和四阶段模型等重要理论研究工作和实验成果，并提出了进一步深入研究的方向。

The simulated results are as follow:the mixture of gas-liquid two-phase can become more sufficient as adding the jet velocity of gas and the immerged depth of jet pipe,and the eddy forms more easily,the time of obtaining steady flow field is shortened.
模拟结果表明:增大气体喷射速度和喷射管的插入深度都可以使气液两相混合更加充分,流场内较易形成涡旋结构,达到稳定流场的时间也比较短。
An Arctic Ocean eddy in subsurface layer is analyzed in this paper with temperature, salinity and current profile data obtained at an ice camp in the Canada Basin during the second Chinese Arctic Expedition in summer of 2003.
利用2003年7—9月中国第二次北极科学考察期间,在北冰洋加拿大海盆的一个冰站上得到的温度、盐度和流速的连续剖面观测资料,对一个次表层的北冰洋涡旋进行了分析。
