Abstract：
The Poisson-Lie structure of non-linear -model is given in O(n)/O(n-1)symmetry space,and the covariant relation between moving frame and fixed frame is discussed using the method of covariant decomposition.It is clear that the field dependence of the r and s matrices results from the connection of S^n－1 manifold.
