中文摘要：

在t-J模型和Fermion-spin理论框架下，研究了准一维强关联Zigzag型材料的自旋动力学．说明了当掺杂一定时，随着次近邻耦合强度的增大，系统出现公度到非公度的转变，而对于耦合强度一定的情况，随着掺杂浓度的增大，系统亦发生从公度到非公度的转变，并且非公度峰的权重随能量的增大而降低。

英文摘要：

Within the t-J model, the spin dynamics of the quasi-one-dimensional strongly correlated zigzag type materials is studied based on the fermion-spin theory. It is shown that the pattern of the neutron scattering peaks depends on both the next-nearest neighbor coupling and doping. The weight of the incommensurate neutron scattering peaks decreases with increasing energy.
