In this paper,we propose a design of the structure and implementation method for the network microcomputer interface virtual laboratory based on the 3D virtual technology. In particular,we focus on the implementation of the interaction based on component. Human-computer interaction based on component is a major component of the virtual lab development. We effectively solve the adjustment of local coordinate system which is set in the component and the material of model by using the coordinate axes converter technique and material technique of 3DMAX. By using the Loader technique and the interaction technique of Java3D,we solve the problem that the material can be lost in importing of the model,the re-combination of components,the operation of virtual scene and model. We propose the good cooperation method between 3DMAX and Java3D,providing a better case for the application of contracting example. 组件 交互 虚拟实验 3DMAX Java3D component interaction virtual experiment 3DMAX Java3D 10.14188/j.1671-8836.2010.04.024 TP391.9 国家高技术研究发展计划（863）项目（2003AA001032）;国家自然科学基金资助项目（60672051） 2010-04-01 2021-04-01 4 56
