摘要
改进Ｏｓｈｅｒ的ＬｅｖｅｌＳｅｔ方法用来计算考虑Ｍａｒａｎｇｏｎｉ效应的液桥自由面及内部的涡流．提出以双调和函数来作为Ｌｅｖｅｌ函数，从而避免了它们的奇性．求出的自由面的波纹形状以及二次涡远比简化算法所得要小．
The Bio-harmonic Function is selected as the Level-function used in the Level-Setmethod. The new defined Level-function overcomes the defects of the Level-function defined byOsher. The internal flow of the liquid bridge with Marangoni's effect taken into consideration isstudied. Besides giving the real free surface, it also proves that the big secondary vortex pairgotten by Zhang doesn't exist.
