The hardware circuit and software of the portable copying instrument is researched . a feasible structure scheme is put forward according to the desired function , at89c51 single chip computer is used as the core of the instrument , zlg7289a and many kinds of new type circuit chip ( including : parallel data memory - ds1245 , sms0823 lcd ) are used as interface during hardware circuit designing , the printer ' s port and rs232 communication interface is also designed 硬件电路以at89c51单片机为核心，以zlg7289a按键组集成芯片作为人机接口，并采用新型电路芯片(包括大容量并行数据存储器ds1245 、液晶显示器sms0823 )设计手持抄录器的硬件电路，并设计了手持抄录器的打印机接口和rs232通信接口，从而简化了电路，减小了手持抄录器的体积，按键的软件实现过程。
In this paper , we mainly discuss association rule mining and improve the conventional algorithm in two different methods in order to adapt to the distributed / parallel data minin g . one is from rules to rules : association rules are firstly mined at the local sites , and then global association rules are generated from these local rules . the other is from data to rules : the local sites exchange their intermediate data results , and then global association rules are generated from these results 本论文中，主要考虑关联规则挖掘算法，从两个不同的角度从理论上探讨了分布式或并行数据挖掘: ( a )由规则到规则:先由各个独立的站点生成各自的关联规则，再在这些关联规则的基础上生成总的关联规则: ( b )由数据到规则:由各个独立的站点交换各自的中间结果来生成总的关联规则。
