In order to evaluate the risk of groundwater contamination resulting from pesticide leaching, a new fugacity model was developed on the basis of former researchers'work. In this model soil was divided into two compartments: unsaturated consisted of three subcompartments: air, water, and soil solid, and saturated phase consisted of two subcompartments: water and soil solid.

This thesis is combined with the project－"design and exploitation of Automotive Constant Drive-Shaft", which is undertaken by the topic team. Based on the structural simplification to three-dimension solid models of ball-cage type and three column-shaft type constant velocity joint, and the three-dimension solid models are obtained by conversion engineering. Altair/Hpermesh software is used here for generating the finite element mesh of key parts of ball-cage type and three column-shaft type constant velocity joint.
