摘要
本文数值求解在微重力环境下作慢自旋的旋转椭球类容器内的部分充液液体的稳态液面．首次采用双向打靶法数值确定液面微分方程中的待定参数和待定的液面边界参数，并且引入了一种变坐标系统，使计算程序能统一处理接触角从０°到１８０°的凹凸两类液面。
This paper studies a numerical implementation to determine the free surface of liquid filled in slowly spinning spheroidal tanks in low gravity condifions. A bilateral shooting method is suggested here to determine numerically the two unknown parameters in the ordinary differential equation governing the meniscus and one indefinite boundary parameter. A variable coordinate-system is introduced here. Using this system, the computer program will be able to treat both kinds of concave and convex meniscus uniformly, e.g., the given contactangle varying from 0°to 180°.
