CHEN Qing-e1,Shi En-wei2,Zhu Si-chao3(1.Tianshui Teacher's college,Tianshui 741001,China;2.Department of Mathematics,Yunnan Normal University,Kunming 650092,China;3.Meteorological Department of Tianshui,Tianshui 741000,China)  
Based on the left-right equivalent relation of smooth map-germs in slgularity theory,the neessary and sufficient condition for unfolding of equivariant bifurcation problem with two types of state variables under a subgroup A1(Γ) of left-right equivalent group to be versal unfolding are studied.
