| 摘 要： | 将Riemann子流形理论推广到Finsler子流形中,并且根据子流形诱导的联络和本身联络不同的特点,利用Chern联络计算了流形及其子流形的Landsberg曲率和S曲率关系,为子流形的进一步研究提供了便利。

| Abstract: | In this paper,submanifold theory of Riemann is generalized to submanifold of Finsler.According to the differences between induction connection and nature connection of submanifold,the relation between landsberg curvature and S curvature on manifold and submanifold is deduced by using the Chern connection,providing basis for the further research of submanifolds. |
