随着我国课程改革的逐步深入,课程的基本理念也愈来愈清晰,作为高中阶段的物理课程必须为学生的终身学习、终身发展、应对现代化社会和未来发展的挑战奠定基础.因此,学生自主学习以及与之相应的自我评价、自我调控学习进程在学生终身学习与发展的过程中就显得十分重要. 相似文献

Phenomena of electron, neutron, atomic and molecular diffraction have been studied in many experiments, and these experiments have been explained by some theoretical works. We study electronic double-slit diffraction with a quantum mechanical approach and obtain the following results: (1) When the ratio of d + a /a=n (n = 1,2, 3,...), orders n, 2n, 3n,... are missing in diffraction pattern. (2) When the ratio of d+a/a≠ n (n =1,2, 3,...), there is a not missing order in diffraction pattern. (3) The slit thickness c has a large affect on the electronic diffraction pattern, which is a new quantum effect. We believe that all the predictions in our work can be tested by the electronic double slit diffraction experiment. 相似文献

合成了2个镉(Ⅱ)金属有机骨架化合物{[Cd(L)(fma)]·0.5H_2O}_n(1)和{[Cd(L)_(0.5)(sdb)]·DMF}_n(2)(L=E,E-2,5-二己氧基-1,4-双(2-乙烯-吡啶基)苯,H_2fma=延胡酸,H_2sdb=4,4′-磺酰基二苯甲酸),研究了它们在金属离子和有机分子的发光传感中的应用。结果表明,Fe~(3+)对配位聚合物1和2的发光强度有明显的猝灭作用。此外,聚合物1和2还对水杨醛具有明显的猝灭能力。 相似文献
