摘　　要：基于奇点理论中光滑映射芽的接触等价关系,讨论含两组状态变量且分歧参数带有对称性的等变分歧问题及其开折的稳定性,得到了一些基本结果,并且用横截性条件刻划了等变分歧问题的稳定性.Based on the contact equivalent relation of smooth map-germs in singularity theory, stability of equivariant bifurcation problems with two types of state variables and their unfoldings in fire presence of parameters symmetry was discussed. Some basic results are obtained. Transversality condition was used to characterize rite stability of equivariant bifurcation problems.
