摘要: 叙述了低温等温情况下，重力和界面张力平衡的激光惯性约束聚变靶丸内表面液氢层分布的Young-Laplace(YL)方程.为了得到靶丸壳内连续液氢层分布的有效解，考虑了液体与固体(衬底)分子间的London-van der Waals力以及该力的迟滞影响.计算结果表明，只有在靶丸内部引力为零或者固体液体分子间的London常量为无穷大时，才能得到等温环境中有均匀厚度的连续液氢层.
Abstract: It has been shown that the Young-Laplace equation based on the balance of the gravitational force and interfacial tension alone cannot produce a valid solution for the profile of a continuous liquid hydrogen layer inside an inertia confinement fusion capsule shell. In the calculated results, the London-van der Waals forces between the liquid and solid (shell) molecules must be included in the equation. The retardation effect of the London-van der Waals forces needs to be taken into account for thick liquid hydrogen isotopes layers. It has been also shown that, in an isothermal environment, a continuous liquid hydrogen isotopes layer with a uniform thickness can only be achieved inside the capsule shell, such as the spherical glass when the gravity is zero or the London constant between the solid and liquid molecules is infinity.
