摘　　要：给出模糊半环上模糊半模(即F_R^A-半模)正和列,复合列的定义,讨论了半模正合列与F_R^A-半模正合列的关系,最后证明了F_R^A-半模范畴中Hom函子的保左复合性.First, the concepts of the compositing sequences and the exact sequences of FR^A-semimodules were given,then the relationship between the exact sequences of semimodules and that of FR^A-semimodules was discussed..Finally, The left Exactness of Hom Functor was proved.

关 键 词：FR^A-半模复合列 FR^A-半模正合列 HOM函子
