In this paper, adhesion process of two material surfaces was analyzed. Formulas for calculating jumping distance were deduced. The results of analysis showed that the jumping distance was retated to the radius of spheres, elastic modulus of the spring and the relative humidity. Effect of relative humidity was also discussed. Basing on single asperity model and the constructive equations for power-law fluid, the formulas for describing the relationship between pull-off force and the rest time were improved. Jump-to-contact force and pull-off-force were measured by a self-built adhesion apparatus.
