Let(M,F) be an n-dimensional Finsler manifold(n≥3),using Finsler geometric basic knowledge and methods,it is obtained that reversible Finsler metric F is of many good curvature propertoes.
在n(n≥3)维芬斯勒流形(M,F)上,利用芬斯勒几何的基础知识和基本方法得到了对称芬斯勒度量F(reversible Finslermetric)具有若干很好的曲率性质;并进一步证明了对称(α,β)-度量F=αφ(s)具有相对迷向平均Landsberg曲率的充分必要条件是F为黎曼度量或Berwald度量,拓展了沈忠民等人的结果。
