在考虑自旋和晶格之间的相互作用情况下，用密度矩阵重整化群方法分析计算了一个自旋为12的一维受阻挫海森堡反铁磁自旋链模型发生自旋-派尔斯相变时动态二聚体与磁耦合系数之间的关系，发现当磁耦合系数趋于0时，在有限阻挫及有限能隙的零耦合状态下，二聚化态将会消失。

In considering the interaction between the spin and lattice case, the relation between dynamic dimer and magnetic coupling coefficient was analysized with the density matrix renormalization group method when a one-dimen-sional blocked frustrated Heisenberg antiferromagnetic spin chain model occurred Spin-Peierls phase change. The re-sults demonstrated that when the magnetic coupling coefficient tends to 0, the dimerization state would disappears in the state for the zero coupling between the limited and finite energy gap.
