摘　　要：介绍了在线数据库驱动的虚拟实验室模型、场景建模技术及其详细设计和实现,重点论述了如何在VRML和ASP中引入XML(可扩展性描述语言)作为数据的载体,让相关场景实现可以由XML这个平面数据库作为数据源来重构场景,实现了虚拟现实场景数据在不同平台间的易交换性。利用VRML实现的在线虚拟集成电路实验室能使远程学生把网络课堂上学习的理论知识和实验相结合,能给远程学生以逼真的学习体验,使之不受资金、位置、仪器和师资等限制。Modeling technology ofonline virtual lab, design and implementation ofscene modeling technique and model ofonline virtual integrated circuit lab were proposed. How to use XML for loading the key data into VRML and ASP was mostly discussed. Successful implementation of these increased strong data exchanged ability of XML. The online virtual IC lab using VRML could make long-distance students relate theory knowledge learned in network classes to experiments. It could give students reality study experience and be not confine to funds, places, instruments and teachers.
