This paper points out the applicable environments for different kinds of scheduling strategies . finally , based on the analysis to tao scheduling service , this paper presents the design and implementation of scheduling apis which support scheduling strategy ( for windowsnt / 2000 and sun solaris ) 在分析和吸收tao调度服务的基础上，面向强实时分布应用的需求，设计和实现了实时分布对象计算环境的基于策略的调度api集( windowsnt / 2000和sunsolaris ) 。
Currently the integrated framework research mainly focuses on the distributed object technology based on software component and software bus . however , the technology of software component and software bus lack for the efficient means to depict the configuration and mutual association of components 目前集成框架的研究主要建立在基于软构件软总线方式的分布对象技术上，然而软构件软总线的研究并未提供有效手段去透明地描述软构件的配置和相互关联。
The reflection approaches based on the theoretic model are firstly used to solve several different kinds of key problems occurring in the co re designing of mobile distributed object platform , i . e . , context - awareness , communication adaptation , transparent object caching , remote replication of server objects 基于上述理论模型，利用反省方法解决了移动分布对象平台核心设计中的一些不同类型的关键问题，包括：上下文感知、通信环境自适应、透明对象缓存、服务对象异地复制等。
After introducing the concepts of distributed object management system and corba briefly , considering the characteristic of the water conservancy project , this paper presents a corba - based object model for distributed information system , which based on concepts of oose and uml notional 本文在简要地介绍了分布对象管理系统的概念和corba后，仔细分析了水利枢纽领域的应用特点，利用oose的方法和统一建模语言（ unifiedmodelinglanguage ， uml ）的符号体系，提出了一个基于corba的枢纽信息系统对象模型。
This paper introduce the distributed object technology and object - oriented modeling language , our works are based on some theory and application about distributed object , corba theory and application , object - oriented software engineering , uml keys and application , integration of uml and corba . finally , we get a useful solution for the developement of distributed system ( linux platform . system modeling , database and so on . ) 本文在介绍分布对象技术和面向对象建模语言背景知识的基础上，阐述相关理论与应用，包括分布对象技术、 corba原理与应用、面向对象软件工程、 uml要点与应用、集成uml与corba等五方面内容，针对分布式系统开发( linux平台，相关的系统建模、数据库、中间件技术)形成一个有效的解决方案。
