摘　　要：当前大部分分布式架构下的实验教学管理系统dETMS(distributed Experimentation Teaching and Management System)在使用过程中存在局部性,进而导致并发访问受限。提出分布式环境下,基于"时序令牌"消除局部性,基于延时处理技术,避免"多次生成一次成功提交"。实验证明,该方法的确解决了dETMS的并发访问限制问题。Most distributed Experimentation Teaching and Management Systems （dETMS） will come about time locality while in use, which results in the problem of concurrent access constraint under the distributed architecture. So under the same circumstance, we put for- ward elimination of access-time-localness by scheduled token, and bypass the usual ＂ multiple generating but only successfully submitting once＂ through the technique of deferred processing. At last, we prove by experiment that the solution presented above does solve problem of concurrent access constraint.
