摘　　要：事务存储是一种并行编程同步方式,与基于锁的同步方式相比具有易于使用、可扩展等优点。对软件事务存储系统竞争管理策略中的序列化调节机制进行了改进,使竞争管理策略在序列化调节的支持下,更加有效地对冲突进行消解。经测试表明,与传统的竞争管理策略相比,带有序列化调节机制的竞争管理策略在高冲突率状况下的性能有明显改善。Transactional memory is a synchronization tool in paralleling program. Compared with traditional lock-basedmethod, it has the advantage of being easy-to-use and extensible. We improved the definition of contention intensity, and introduced it to the use of conflict resolution. In the serialization adjustment schema, the contention manager and scheduler help each other： CMs exploit the parallelism while the scheduler guarantees the lower bound of performance. The experimental result shows that the contention management policy under serialization adiustment support has better performance than the one without any support, especially when the contention ratio is high.
