Earthworms are a typical soil animals under the sticky wet soil conditions , can move freely without clay . Earthworms whole body or whole body has a good the visbreaking resistance reduction function , its surface is non- smooth surface electroosmosis flexible body , body surface lubrication and its unique exercise multifactorial coupling results . Less adhesion and resistance of the earthworm body surface to study the soil on the ground mechanical visbreaking off has important practical significance and broad application prospects . Earthworm body surface were observed and analyzed using a similar principle to the arrangement of the holes , the number of holes and the surface morphology of factors , design and processing bionic sample , the use of the tiny soil adhesion test systems and precise control of flow rate peristaltic pump , bionic sample the soil adhesion characteristics of the experimental biological non- smooth as well as bio- lubricating function of the bionic sample visbreaking reduction in resistance . Range analysis , preferably a bionic sample , further analysis of the water content , the positive pressure , flow rate , as well as factors such as the forward speed of the reduction in resistance of bionic sample visbreaking function .
