摘　　要：根据Y(SL(2))代数的自旋实现,给出李代数范畴内同权量子态之间的跃迁算符与Yangian代数范畴内不同权量子态之间的跃迁算符.利用外磁场下Y(SL(2))代数的自旋实现,给出含时量子态之间的跃迁算符.According to the spin realization of Y（SL（2）） algebra, this paper can give the transition operators that cause transition among quantum states with the same number of Lie algebra area,and also give the ones that cause transition among quantum states with different numbers of Yangian algebra area. Applying the spin realization of Y（SL（2） ） algebra in an extra magnetic field, it can give the transition operators among the time quantum states.
