Abstract: Based on the surface analysis of ph.hupeiensis,cylindroiulus teutonicus,manis pentadactyla pusilla J.Allen and microtus manderinns Milne-Edwards,which have a typical flexible nonsmooth surface,this paper described the flexible nonsmooth surface qualitatively and analyzed its reducing adhesion characters. The experiment was done to test and verify the effects of reducing adhesion about the flexible nonsmooth surface. This will lay a foundation of developing the flexible bionic technology.
