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.

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.

Stratification and the subsequent rollover phenomenon are serious problems in the storage of LNG.

Dynamics of eddy-induced Kuroshio variability in Luzon Strait;

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.

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.
