新工科背景下通识教育类课程的教学模式探索*——以材料导论课程为例

通识教育类课程是新工科背景下推进大类招生与专业分流的重要组成部分。针对高校通识教育类课程教学过程中存在的弊端,从课程定位、教学方式、资源配置和评价体系等4个方面进行统筹规划、整体推进,以最大程度地提升学生的学习效果和人才的培养质量,旨为通识教育类课程的教学改革提供一定的参考。     

Realizing the Underlying Quantum Dynamical Algebra SU（2） in Morse Potential

Exactly solvable models are important in quantum physics. Usually, there are some underlying quantum dynamical algebras （QDA） inherit in these physical models. For instance, the QDA SU（1, 1） has been revealed in some important one-dimensional exactly solvable potentials, such as the harmonic oscillator, PSsehl-Teller potential, the radial Kratzer molecular potential, etc. However, the case for the one-dimensional Morse potential has not been studied in Ref. . Namely, whether the Morse potential possesses an QDA SU（1, 1） or not is still an open problem.
