英文摘要：

In this paper,we study an affine Lie algebra L,corresponding to the finite dimensional Kac-Moody Lie algebra L=sl（l＋1,K） where K be a field of characteristic p2.By using root space decomposition of L with respect to a torus and distinct partition,we prove that L is a restricted Lie algebra and prove that the central elements of L act trivially on any restricted L-module whose Z-graded weight spaces are of bounded dimension.
