本文研究一维量子晶格气中粒子最近邻相互作用的非线性性质,给出这一模型的孤子理论。同时,导出孤子能量以及有效质量的表达式。In this paper, the non-linear properties of the nearest neighbor interaction between particles in one-dimensional quantum lattice gas are investigated, giving out the soliton theory of the model. The expressions of the solitons' energy and the effective soliton mass are also derived.
