摘　　要：求出了一维反铁磁链中双亚格点模型的孤子解,并求出了孤子宽度、峰值、静止能量和有效质量.在al=bl+和al=-bl+两种情况下求方程的精确解.The soliton solution in the two-sub-lattice model of a one-dimensional anti-ferromagnetic chain is found. The width, the peak, the rest energy and the effective mass of the soliton are given. The two cases, i.e, al = bl^＋ and al = - bl^＋, the exact solutions of equations are considered.
