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.
