以CO2超临界状态及制冷应用为例,展示如何以解析关键概念/技术背后的物理化学原理为纽带,在课堂教学中有机融入思政案例(如北京冬奥会制冰造雪)和开展课程思政“翻转课堂”教学;籍此使学生体会到物理化学原理在解决国家重大需求中发挥的关键作用,在强化学科自信的同时,增强学生学以致用、服务国家、绿色发展的意识和开拓创新的精神。CO2超临界状态及应用是“物理化学”单组分相图中的知识难点和应用热点,在教材中常以知识拓展的形式出现,不仅与专业知识结合不紧密,学生对此也缺乏深刻理解。有鉴于此,我们以“讲透”CO2超临界状态和制冷技术背后的物理化学原理为抓手,依据知识间内在关联,环环相扣、水到渠成地开展课程思政教学。为了提升思政教学效果,还综合采用了任务驱动的自主学习、翻转课堂及课后拓展相结合的多元思政教学手段,引导学生自主发掘思政素材,实现自我思政教育,从而达到了价值塑造、知识传授和能力培养三位一体的教学效果。 相似文献

Electronically non-adiabatic processes are essential parts of photochemical process, collisions of excited species, electron transfer processes, and quantum information processing. Various non-adiabatic dynamics methods and their numerical implementation have been developed in the last decades. This review summarizes the most significant development of mixed quantum-classical methods and their applications which mainly include the Liouville equation, Ehrenfest mean-field, trajectory surface hopping, and multiple spawning methods. The recently developed quantum trajectory mean-field method that accounts for the decoherence corrections in a parameter-free fashion is discussed in more detail. 相似文献
