“互联网+”时代，技术加之于教与学的层次和范围都在扩大，并为其带来了学习环境和学习方式的变革，特别是 VR及AR技术的发展，推动着传统物理实验室向虚拟实验室转变。为进一步实现虚拟实验从理论研究走向实际应用，文章采用理论分析的方法，依据学科本体理论，首先从概念本体、方法本体和应用本体三个维度对初中化学实验知识进行了本体分类，并对其内容及相互关系进行了深入探讨；然后以此为基础，从基础知识学习、基本技能训练和综合应用三个模块进行虚拟实验室模型构建；最后从理论和实践两个方面出发，依据化学虚拟实验室对不同类型本体知识的应用模式提出了相应的应用支撑策略，以期为虚拟实验室的开发和应用提供框架性依据。
【英文摘要】：
In "Internet+" era, the level and scope of technology-enhanced teaching and learning are expanding, which brings about the reforms of learning environment and learning style. The development of VR and AR technology has promoted the transformation of traditional physics laboratory to virtual laboratory. For further implementation of virtual experiment from theoretical research to practical application, this article, according to the subject ontology theory, first adopts theoretical analysis to classify the knowledge of chemistry experiment in junior middle school from the concept of ontology, method ontology and application ontology three dimensions, and discusses their contents and relationships. Then a virtual laboratory model is constructed, including basic knowledge learning, basic skills training and comprehensive application three modules. Finally, this paper puts forward corresponding application support strategies according to different types of ontology knowledge models in chemical virtual laboratory to provide the framework for the development and application of virtual laboratories.
