摘　　要：针对传统化学教学的局限性及现有虚拟化学课堂的不足,以Unity3D为基础设计并实现了虚拟化学智能课堂系统.构建虚拟场景并导入Unity3D引擎,通过C#脚本和粒子系统开发虚拟仿真实验;为解决多人虚拟场景下权限分配问题,实现了采用权限策略的智能辅助模块,为不同学生分配不同权限并提供文字视频等提示功能;通过Spring Cloud框架对系统功能进行拆分,同时使用Redis优化系统.系统适用于中学化学教学,实现了具有权限控制及高仿真的虚拟实验,有效解决虚拟场景下权限问题,提升学习效率,且具有高可用性等优点.With regard to the limitations of traditional chemistry teaching and the deficiencies of existing virtual chemistry classrooms,a virtual chemistry intelligent classroom system based on Unity3D has been designed and implemented.A virtual scene is constructed and imported into the Unity3D engine,and virtual simulation experiments are performed through the C#script and a particle system.For authority allocation in multi-user virtual scenes,the intelligent auxiliary module with authority strategy is designed to assign different ranges of authority to students and provide prompt functions such as text and video.Besides,the system functions are split through the Spring Cloud-based framework,and the system is optimized by Redis.This system is suitable for chemistry teaching in the middle school.It implements highly-simulated virtual experiments with authority control to solve authority problems in virtual scenarios and improve learning efficiency,with high availability,etc.
