在非绝热近似下 ,研究了一维spin_Peierls系统中晶格量子涨落对系统性质的影响 ,讨论了系统的二聚化相变、单粒子激发和双粒子束缚态 .结果表明 ,量子晶格涨落会抑制晶格的二聚化 ,破坏系统的spin_Peierls基态稳定性 .在临界点 ,系统发生从二聚化spin_Peierls态向无能隙态的相变 .自旋 声子耦合强度对束缚态能隙的影响比单粒子激发谱能隙显著 In non-adiabatic approximation, the effects of lattice quantum fluctuations on the system properties in a one-dimensional spin_Peierls system are discussed, and the dimerization phase transitions, single-particle excitation and double-particle bound states of the system are discussed.The results show that quantum lattice increases The droplet will inhibit the dimerization of the lattice and destroy the stability of the ground-state spin-plugiels of the system. At the critical point, the system undergoes a phase transition from the dimer-spin-like state to the non-energetic state. The influence is more pronounced than that of single-particle excitation
