摘　　要：实时协同编辑系统作为CSCW的一个重要应用,近年来得到广泛研究。对目前协同编辑并发算法的研究现状进行了探讨,比较了国内外现有协同编辑并发算法,包括dOPT、adOPT、SOCK2、SOCK3、SOCK4等算法。然后根据实际应用需求,在GOT算法基础上实现了焦点维护和历史缓存清洗。最后,给出了在一个协同编辑器Z-Office中的应用,目的是提高协同编辑器的实用性和响应速度。The research work of real-time cooperative editing system, which is one of the classic implementation of CSCW, is greatly emphasized in recent years. The research status of these days is discussed and the characteristics ofdOPT algorithm, adOPT algorithm, SOCK2, SOCK3, SOCK4 algorithm and so on are compared. According to actual application demand, focus maintenance and history buffer cleaning based on GOT algorithm is realized. Application of the in algorithm one cooperative edit system Z-office is present. The purpose of introducing the algorithm is improving practicability and response speed of cooperative editing system.
