【摘要】 国家发展和改革委员会在《国家教育事业发展"十三五"规划》中提出了新工科教育的目标要求,即提高学生的实践和动手能力。而化工行业本身有安全上的特殊性和操作工艺的复杂性,这就决定了很多具体过程无法让没有经验的学生去实践,化工专业生产实习目前也只能以观察为主。化学反应工程课程中很多工程理论知识的应用如果单独进行模拟展示,成本巨大,且无法在工业现场实现。近年来随着计算机软硬件技术的进步,三维虚拟场景视图的虚拟现实(VR)技术可实现化工工业场景的逼真模拟,学生借助头盔显示器、移动手柄等传感设备与虚拟化工环境发生交互作用,产生沉浸式感受,实现具体设备的操作和控制,这为提高化工学科学生的实践动手能力提供了可行的新途径。文章以煤制甲醇组合反应器的VR软件可视化建设过程为基础,对VR技术应用于化学反应工程课程教学进行了分析研究,对教学效果进行了评估,并总结和探讨了VR教学的优势和劣势及其与传统教学融合发展的问题。更多还原

【Abstract】 The National Development and Reform Commission′s goal on new engineering education in the13 th Five-Year Plan for the Development of National Education calls for improving students′practical and hands-on abilities.However,the chemical industry has its own safety particularity and complexity of operating technology,which determines many specific processes are impossible for students with no operating practice to carry out.The production practice of chemical specialty currently is only based on observation.The application of engineering theory knowledge in chemical reaction engineering course cannot be realized on the industrial site because of its huge cost if the industrial companies display it in a simulated way.In recent years,with the progress of computer software and hardware technology,the virtual reality technology of three-dimensional virtual scene view has achieved realistic simulation results for chemical industry scenes.It enables students to immerse in the real chemical plant by means of various sensing devices such as helmet-mounted displays and mobile handles,and realizes the operation and control of specific equipment,which providing a feasible new way to improve the practical ability of chemical students.Based on the visible construction process of VR software for coal-to-methanol combined reactor,this paper analyzes and studies the practical case teaching of VR teaching technology applied to chemical reaction engineering teaching,evaluates the teaching effect,and summarizes and discusses the advantages and disadvantages of VR teaching and the development of traditional teaching integration.更多还原
