简介:摘要微课程是微型学习的一种具体形式,主要以短时视频为载体记录微型化的教学内容,是对传统教学模式的革新。借助微课程可以有效利用碎片化时间进行随时随地学习,有助于形成新的学习理念。目前关于微课程的研究大多仍在阐释其理念与应用前景,故需要对实践中的微课程设计模式进行深入的审视与总结,本文对多种设计模式进行探讨,以期为微课程理念如何更好地促进学生学习寻求启示。

简介:wurtziteZnO半导体的电子结构和磁性与稀土元素做了(RE=La,Ce,Pr,下午,Nd,Sm,Eu,Gd,Tb,Dy,惊讶,嗯,Tm和Yb)原子用极化纺纱的密度被学习功能的理论基于完整潜力的线性扩充飞机波浪(FP-LAPW)在Wien2k代码实现了的方法。在这条途径,概括坡度近似(GGA)被用于交换关联(XC)潜在。我们的结果证明在导致的ZnO的RE离子的替换在乐队差距旋转极化的局部性的状态。而且,学习数据管理系统混合物为大多数学习元素在掺杂物集中x=0.625%保留了半metallicity,与在费密水平的100%旋转极化(EF)。这些混合物的全部的磁性的时刻由于在EF,当小导致的磁性的时刻也在另外的无磁性的原子上存在时。最后,远、近的配置之间的精力差别被调查。房间温度强磁性为在近的配置的重新做的ZnO是可能的,这被发现。自从RE-RE分离,足够长(远配置)因为磁性的联合,系统变得顺磁或antiferromagnetic地面状态。
