摘　　要：随着虚拟仪器的网络化发展,各种测试数据格式不兼容、数据交换以及共享困难的现象日益突出。XML(eXtensible Markup Language,可扩展置标语言)为虚拟仪器开发者提供了有利的解决方案,并且逐渐成为Internet上一种新的数据表示和数据交换标准。该文对网络化虚拟仪器进行了简要的概述,剖析了XML的特点及对网络化虚拟仪器的适应性。在此基础上探讨XML与网络化虚拟仪器融合的切入点,着重阐述了XML在数据采集、数据处理、数据发布、数据管理、开发部署等方面的应用。As the development of network-based virtual instrument（NBVI） the problems of non-compatibility of various measuring data format,data exchange and data sharing occur obviously.XML provides the effective solutions for the researchers of VI,and becomes gradually a new standard of data expression and data exchange in Internet.Users are capable to do interactive data transferring in floor in network,to display the wave,spectrum characteristic value of selected data with this technique.This Paper introduces the concept of NBVI expression and analyses the feature of XML and its adaptability to NBVI,discusses the amalgamation point of unifying XML and NBVI,and describes data acquirement,data declaring,data management and develop-management etc.Finally the article uses a typical distributed measuring-control system to explain the flexible application of XML technique in some links of the system in detail.
