摘　　要：基于VRML技术,结合虚拟实验的开发环境、现状特点以及发展前景,研究虚拟实验制作所用到的技术,设计制作仿真性高的虚拟试验。本研究分析了虚拟实验的功能特性和操作方式,实现了一个数字电路的虚拟实验,利用VRML的脚步程序仿真了74LSO4芯片逻辑功能测试的全过程。该虚拟实验交互界面的真实感强,提供的三维虚拟环境具有亲临其境的真实感。用户可对实验过程进行操作控制,具有操作性交互性强的优点。研究表明基于VRML的虚拟实验有很强的应用前景,为远程教育的网上实验提供条件。Design a high simulation virtual experiment, based on VRML technology, combined with developing environment, the features and the futttre of virtual experiment, researching on the technologies used in designing virtual experiment platform. Analyzed the function- al features and operational way of virtual experiment,implemented a virtual experiment of digital circuit, using VRML footstep program to simulate the whole process of the 74 LOS4 chip logic function test. The virtual experiment interface has strong true feeling. The 3D virtual environment that system provided has true feeling of attend personally. The user can operate an experiment among them, with advantage of interactivity and operation. Research shows that the virtual experiment based on VRML has strong application, providing remote educa- tion with online experiment conditions.
