英文摘要：

In this paper, the approach to construct higher super matrix spectral problems from a 3×3 super matrix spectral problem is presented. As an example, we construct a 5×5 super spectral problem which is associated with the super AKNS equation from the 3×3 super AKNS spectral problem, by use of the binary nonlinearization method, new constraint of super AKNS equation is obtained. The corresponding new integrable decomposition of the super AKNS equation is presented also.
