摘要
采用虚拟现实、Web GL和H5技术,开发了4种条件下的电子发射实验,为实验者设置了"电子发射→电子传输→电子收集"完整的虚拟仿真过程,将能带结构、电子行为受外界条件改变成可视化,帮助学生形象理解相关物理过程。以"不可及"的卫星电推进中和器作为电子发射应用载体,感知不同结构参数对电子行为的影响,培养学生的工程应用能力。实验以中心服务器为主,学生可通过终端远程访问。通过仿真,学生可深入理解固体物理中电子发射的物理过程,帮助学生实现理论到应用的衔接。
Using virtual reality, Web GL and H5 technology, the electron emission experiments under four conditions are developed. A complete virtual simulation process of "electron emission → electron transmission → electron collection" is set up for the experimenters. The band structure and electronic behavior are visualized by the changes of external conditions, which helps students understand the image. Taking the "inaccessible" satellite electric propulsion neutralizer as the application carrier of electron emission, students can cultivate their engineering application ability by perceiving the influence of different structural parameters on electronic motion. The experiment is based on the central server, and students can access it remotely through the terminal. Through the simulation experiment, students can deeply understand the physical process of electron emission in solid physics, and realize the connection from theory to application.
