摘　　要：得到了一维量子格气模型中的孤子解，给出了孤子的宽度、峰值、静止能量及有效质量．结果表明孤子的存在是有条件的，孤子的宽度。The soliton solution in the quantum lattice gas model in one dimension is found. The width, the peak, the rest energy and the effective mass of the soliton are given. The condition of the soliton existing is pointed out. The dependence of the width, the peak and the energy of the soliton on the attraction energy between nearest neighbor particles are considered.
