摘　　要：为了进一步探究和完善超对称模型下的重整化理论,在超对称模型下研究了μνχ-顶点的单圈三角图的在壳重整化.通过计算该顶点的发散部分,并推导出与发散部分对应的重整化常数,从而证明了三角图的发散部分与抵消项完全相消.研究表明:当处理同样的重整化问题时,在超对称模型下三角图和重整化常数的选取与标准模型有着显著区别.In order to explore and perfect the renormalization theory of the super-symmetry model, on-shell renormalization of the one loop triangle diagrams for the vertexμvx^- is studied. The divergent part is ealculated. The renormalization constant is derived to obtain final finite results, that is to say the divergences of the triangle diagrams have been eliminated completely. The work shows that there is differ- enee between the standard model and the super-symmetry model on the selection of the triangular diagrams and renormalization constants.
