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.

补充资料:液HeⅡ的涡旋线(vortexlinesofliquidHeⅡ)
液HeⅡ的涡旋线(vortexlinesofliquidHeⅡ)

圆柱形容器盛以HeⅡ液体使其绕柱轴旋转,在转速超过临界速度vc时,液HeⅡ就获得一定的角动量。费因曼设想此时液体内并不处处都满足`\nabla\timesbb{v}_s=0`,而存在某些穿出液面均匀阵列的奇异点(涡线),而奇异点的强度用环流表征:K=∮vdl,相应的对称解vs(r)=θK/2πr,θ为转动角θ方向单位矢量,r为液体内取任一点的半径,由此设想给出的涡旋线密度n0=2ω0/K,ω0为角速度。他还设想液HeⅡ中的环流是量子化的,即mK=∮pdl=nh,K=nh/m,n为正整数,h和m分别是普朗克常数和氦原子质量,一个量子值K0=h/m=0.997×10-3cm3/sec。这个预测已为实验所证实,故是量子液体,则旋转中的液HeⅡ仍然是超流的。理论给出单位长涡旋线的能量Ev近似为:

$E_v\approx\frac{\rho_sK^2}{4\pi}ln\frac{R}{\xi}$

这里R为圆柱容器的半径,ξ是涡旋核的半径,实验指出它是原子量级ξ≈1A°,ρs为超流液体密度。若R≈1cm,则Ev≈1.3×105eV/cm。
