This paper, through comprehensive analysis, deals with the problems in joint venture school cooperation in southern Jiangsus secondary schools by studying the background and current situation of the joint venture school cooperation, special topic survey, questionnaires and interviews. The problems are: 1. a small number of schools lay too much emphasis on benthamism; 2. overseas curriculum is introduced without digestion; 3. the joint venture cooperation in vocational schools is not accustomed to the local need; 4. many difficulties exist for a smooth connection with domestic and/or overseas college enrollment.

Second, based on the screw theory, the'virtual joint'concept was proposed. By means of this concept, the conventional trajectory planning in Cartesian space was converted in the 'virtual joint'space, that is, the complex trajectory planning in Cartesian space was simplified by utilizing the trajectory planning in the'virtual joint'space.

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.
