相对时序 meaning in Chinese

relative chronology

Real _ time requirement and time sequence consistency are important symbols in dems , the paper analyses thoroughly factors that system real _ time is restricted , and merits that main memory is used as a storage medium . in order to satisfy system real _ time and openness , distributed database in experiment & measurement system unites real _ time main memory database and sql server 2000 . the paper discusses the time sequence consistency in dems and introduces the concept of absolute time sequence consistency and relative time sequence consistency
实时性及时序一致性是试验与测试系统分布数据库性能的重要标志，论文深入分析了制约系统实时性的因素及以内存为存储介质的优点，为满足系统的实时性与开放性，引用了实时内存数据库与sqlserver2000相结合的试验与测试系统分布数据库设计思想；时序一致性表现为绝对时序一致性和相对时序一致性两方面，结合试验与测试系统自身特点，利用优先级解决绝对时序一致性和用数据视图解决相对时序一致性问题。
