| Abstract: | in this paper,considers the cover layer of solution for a higher order ellipitic equation with turning points. According to the various layer sequence it uses various stretch variables and respectively constructe boundary layer correction terms with various quantitative orders,and the uniformly valid asymptotic expansion of arbitrary order of solution is given. |
