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
