摘要

当微量液体被吸附在具有微小间距的两个固体表面时，会出现液桥现象. 本论文以两狭长平板间的液桥为研究对象，建立三维液桥模型，计算液桥两端马鞍形液体体积，得到液桥形态特征参数与体积之间的数学关系.

Abstract

When a small amount of liquid is adsorbed on two solid surfaces with tiny spacing，the

phenomenon of liquid bridge occurs. In this paper，the liquid bridge between two narrow and long

flat plates is taken as the re- search object，and the three-dimensional liquid bridge model is established to calculate the saddle-shaped liquid volume at both ends of the liquid bridge.The relationship between the characteristic parameters of the liquid bridge shape and the volume is obtained.

Key words： long and narrow parallel plate; liquid bridge; saddle-shaped volume; cylinder method
