In this paper,with the help of the theory of quotient space and Morris sequence,the Lagrange multiplier theorem of vector extremal problems with set-to-set maps is extended to the nonpointed ordered convex cones.

• 本文在非常一般的偏序线性空间中 ；利用 Morris序列以及商空间理论 ；讨论了序凸锥为非点式锥 ；且所含映射均为集到集映射的向量极值问题的Lagrange乘子定理 .
