| 摘 要： | 通过对移动计算环境下已复制数据一致性的研究，提出了一种新的数据复制控制协议。该协议对已复制数据库对象的读操作或写操作等临时信息进行探索，使单副本可串行化和最终一致性两个标准可以同时得到保证。文章最后还对协议的正确性进行了分析。

| Abstract: | This paper is based on the study of the replicated data consistency in mobile computing environments and proposes a new data replica control protocol.This protocol explores the temporal information about the moment where a replicated database object is read or updated,so that the two criterions of one-copy serializability and eventual consistency can be guaranteed at the same time.Finally,this paper analyzes the correctness of protocol. |

| Keywords: | mobile computing environments data replication one-copy serializability eventual consistency |
