摘　　要：给出了连续的海森伯自旋链的运动方程的拉克斯对 ,运用反散射变换讨论了自旋链的非线性自旋波进动 。Lax pair is given for the equation of motion of a continuum_Heisenberg_spin_chain. In terms of inverse scattering transformation, precession of nonlinear spin waves in spin chain is discussed. The difference of solutions is obviously obtained by a spin rotation.
