摘　　要：土壤动物的非光滑体表是其减粘降阻的重要原因,而体表的非光滑程度与其润湿性也有着密不可分 的关系。本文以非接触式三维扫描仪获取蚯蚓体表的空间数字信息,计算其运动方向上的非光滑单元密度,测量 了蚯蚓体表不同部位的接触角,并分析了非光滑单元密度与接触角的关系。The non-smooth surface of the soil animal plays an important role in its function of reducing adhesion and resistance when it moves, and wettability is related to its non-smooth surface. Numerical information of the surface of earthworm is acquired by a laser 3D-scanning measurement device. The density of the non-smooth unit of the earthworm skin on the moving direction is calculated in this paper. And the contact angles on different part of earthworm skin are tested. Finally it is described that the relati...
