The thesis chooses 'classroom', a special space-time continuum, as the breakthrough point of the research and intends to take IT classroom assessment as the complement of IT Grade Examination and Provincial Examination, and provides IT teachers in practice with operational assessment methods. 本文选择课堂这个特殊的时空作为研究中学信息素养评价的切入点,把信息技术课堂评价作为信息技术等级考试和会考的补充,并通过本研究为一线的信息技术教师提供可操作的评价方法。
Vary space-time concept reflect the culture difference among folks as well as different jumping-off point of philosophy. 不同民族的时空观念,反映了各民族的文化差异,也可以说是哲学起点的不同。
This article assume that space-time has internal structure. The principle bundle P ( M, G) is set up. We select the metric ij ( X) which is connected with the point of space time on the group G. 本文假设时空具有内部结构,建立于主丛P(M,G),在群G上选取与时空点有关的度量ψ(ij)(x)。
In this paper, we combine these two betterments and suggest a new method named the space-time varying and dip scanning stack KL transform, and also point out what should be paid attention to in using this new method. 作者在本文中将这两个方面的改进有机地结合起来,提出应用时空变-倾角扫描叠加KL变换对地震资料进行处理,并指出使用该方法时需要注意的一些问题。
