摘　　要：传统的面向对象程序设计(OOP)机制由于缺少对面向对象分布实时计算(DRTC)特殊性的计算语义支持,不能很好地支持DRTC应用。解决上述问题的一个有效途径是扩展传统的OOP机制、为DRTC特殊性提供计算语义支持。提出了一个面向对象分布实时计算模型;研究设计了支持该模型的几种实时远程操作引用机制:同步远程操作引用、异步远程操作引用和多复本实时操作引用;并在一个实验分布实时计算系统EDRTCS中进行了实现。Extending object-oriented programming(OOP) to distributed real-time computing (DRTC) environment has been and is the focus of researches around the world in recent years. In traditional object-oriented computing mechanisms, little computing semantics support is provided for distributed real-time computing applications. It is argued in this paper that the key to solve the problem is to integrate the distributed real-time computing semantics into the object-oriented computing mechanisms. Based on the above policy, this paper presents an object-oriented distributed real-time computing model. In support of the computing model, several real-lime remote operation invocation (RT-ROP1) mechanisms are designed, namely, synchronous RT-ROPI mechanism, asynchronous RT-RORT mechanism and replicated real-lime operation invocation (R-RTOPI) mechanism All these RT-ROPl mechanisms are implemented in an experimental distributed real-lime computing system -EDRTCS.
