摘　　要：Object-Z语言缺乏完整的时态描述能力,如无法表达操作在特定时间之后执行或按某种周期执行等,也不具有操作补偿等概念。针对这些问题,在Object-Z中集成实时概念和分布式时态逻辑,提出DTL-Real-Time Object-Z规格语言,该语言能有效地描述操作的时态驱动、事件驱动、操作补偿等因素,分析和说明了该语言的语法和语义,最后通过对责任授权模型的形式化描述说明了该语言的表达能力和应用。Due to the absence of abilities to describe temporal factors entirely in Object-Z,such as describing the execution of operations at some specific time or in some cycles,and the absence of concept of operation compensation,the paper presented DTL-Real-Time Object-Z：an integration of real-time Object-Z with the Distributed Temporal Logic.The language can express the event-driven,time-driven and compensation factors of operations effectively.The syntax and semantics of the language were analyzed and discussed.Finally,expressiveness and application of the language were showed by formal description of an obligation authorization model.
