新工科视域下物理公共选修课知识体系建设研究——以东北电力大学为例

作为实施物理通识教育的重要载体,物理公共选修课的课程知识体系需要得到合理建构和适时革新,以发挥其支撑新工科建设的独特作用。本文以东北电力大学物理公共选修课的课程建设经验为例,详细论述了以新工科为导向的物理通识教育课程知识体系建设的相关问题。该实践研究可为物理通识教育课程改革提供重要参考,对新工科专业的建设与发展具有一定的参考意义。

Pressure-and temperature-dependent luminescence from Tm^(3+) ions doped in GdYTaO_(4)

Luminescent properties of Tm^(3+)-doped GdYTaO_(4) are studied for exploring their potential applications in temperature and pressure sensing.Two main emission peaks from ^(3)H_(4)→^(3)H_(6) transition of Tm^(3+)are investigated.Intensity ratio between the two peaks evolves exponentially with temperature and has a highest sensitivity of 0.014 K^(−1) at 32 K.The energy difference between the two peaks increases linearly with pressure increasing at a rate of 0.38 meV/GPa.Intensity ratio between the two peaks and their emission lifetimes are also analyzed for discussing the pressure-induced variation of the sample structure.Moreover,Raman spectra recorded under high pressures indicate an isostructural phase transition of GdYTaO_(4) occurring at 4.46 GPa.

新工科选修课的通识教育化研究——以“纳米材料与器件”为例

基于通识教育思维,以“纳米材料与器件”为例,论述新工科专业选修课的建设发展问题。相关课程应依据科技、产业进展,丰富、明晰建设目标,合理衍生知识体系,构建逻辑自洽、特色鲜明、统筹兼顾的教学内容;通过多维度思政使智育与德育紧密结合,提升育人水平;采用弥合“教”与“学”偏差的改进策略,持续优化教学,更好地支撑学生发展。
