摘　　要：运用连续极限近似,求解二维单原子晶格的非线性振动方程,在只考虑最近邻相互作用下,得出在x,y 方向的力常数存在一定关系时,二维单原子晶格的非线性振动具有线孤子解。By virtue of the method of continuum limit, we obtained the line-solitons of the vibration of lattice in two-dimensional nonlinear monoatomic lattice. through that the equations of nonlinear vibration of two-dimensional monoatomic lattice are solved. Under considering most adjacent reaction and existing the certain relation of constant offorce in x with y.
