基于HTML5的虚拟实验建模及实现

Modeling and implementation of virtual experiment based on HTML5

因虚拟实验室可有效规避传统实验室的缺点,突破时空限制,无论是学生还是教师都可自由进入实验操作仪器,故应用HTML5技术开发实现了中学物理化学虚拟实验。虚拟实验采用几何建模和物理特性建模的方法建立了器件模型,并将其添加到实验场景中,在建立器件关系的基础上实现了过程建模,完成了交互设计,并对实验操作和数据结论进行了测评。结果表明,基于HTML5开发完成的虚拟实验在浏览器上运行,具有强交互性、高仿真度。

Since the virtue laboratory can effectively avoid the disadvantages of the traditional laboratory,has broken through time and space constraints,and both students and teachers are free to access the experimental operating instrument,the HTML5 technology is applied to develop and realize the virtual experiment for physics and chemistry courses of middle schools.In the virtual experiment,the methods of geometric modeling and physical feature modeling are adopted to establish the device model and add it in the experimental scene.The process modeling is realized,interactive design is completed,and experimental operation and data conclusions are evaluated based on the establishment of device relationships.The results show that the virtual experiment developed and completed on the basis of HTML5 has strong interactivity and high simulation degree while running on browsers.
