摘　　要：利用单向S-粗集,给出知识堆垒及它生成的知识垛的概念,知识垛具有动态特性,给出粗知识垛的生成,提出粗知识垛生成原理及还原定理,提出粗知识垛分辨尺度及识别准则与识别定理,并给出应用。By employing one direction S-rough sets, the concepts of knowledge addition and knowledge battlement generated by knowledge addition were presented, where knowledge battlement has dynamic characteristic. Then rough knowledge battlement generation was given, and the generation principle and the reversion theorem of rough knowledge battlement were proposed. Furthermore, the discernibility metric of rough knowledge battlement was given, and the recognition rule and recognition theorem of rough knowledge battlement were proposed. Finally the applications were given.
