摘要： 就微重力环境下处于外围流体浴槽之轴对称粘滞流体桥振动动力学问题，建立了近似振动传播模型。该模型综合考虑了流体桥本身及外围液体浴槽的粘滞效应，将其纳入相应的统一的数理方程之中。解之，得到了稳态流体桥振动的界面函数及相关的其它结论。这些结论与经由ＣｏｓｓｅｒａｔＭｏｄｅｌ和ＬｉｎｅａｒＴｈｒｅｅ－ＤｉｍｅｎｓｉｃｎａｌＭｏｄｅｌ所得结论相近，但却同时包纳了桥内外的粘滞效应。

Abstract: his paper establishes a vibration propagation model upon axisymmentric viscous liquid bridges in a viscous bath under the microgravity condifions. The model takes into account the viscous effects of both liquid bridge and surrounding bath and includes these effects in a corresponding uniform mathematical equation group. The solution gives the mathematical expressions of the interface deformation function for bridges with equilibrium vibration state and the other concerned significant results,which are similar to the conclusions got by Cosserat Modeland LinearThree-Dimension Model.
