摘　　要：根据分布式环境下虚拟试验的特点,提出一种面向试验对象的建模方法,采用虚拟试验对象建模语言(VTML)完成建模任务;作为试验资源应用中相互通信的"公共语言",VTML语言能够准确定义试验场景中的各种对象,实现了试验资源应用的语义互操作,将传统的面向对象的分布式系统和基于发布-订购的系统功能结合起来,兼有两种机制的长处,为用户提供了强大的编程抽象,同时消除发布订购系统中编程人员要明确存储接收数据的繁琐任务;经实际应用表明,VTML能够帮助模型开发人员完成虚拟试验场景中的建模任务,有效实现试验场景资源内部的可操作性、可重用性、可组合性。According to the features of virtual experiment under distributed environment, propose an object--oriented modeling method which aims to complete a modeling task by virtual test object modeling language （VTML）. As a common language used in experiment re- sources applications, VTML can accurately define various objects in experiment environment, it realizes semantic interoperability between ex- periment resource applications and integrates the traditional distributed system which is object--oriented and the functional syste--m based on publish--subscribe together. Bearing the advantages of each system, VTML provides a powerful abstract programming to users and elimi- nates the tedious task in publish--subscribe system which requires the programmer to store the received data explicitly. Pra--ctical applica- tion shows that VTML is able to help the programmer to accomplish the modeling task in virtual experimental environment and thus to realize the maneuverability, reusability and composability of experimental environment resources.
