Study and Application of Sweller of Low Temperature Cement Slurry

一 种低温 油井水泥 膨胀 剂的研究和应用

Therefore we first discussed the inner causes of the excellent math ability of gifted students in the framework of cognitive load theory proposed by Sweller .

为此，我们首先从认知负荷理论的角度分析了 学 优生数学能力优异的内在原因。

Improving cementing operation result by using SEP sweller and KQ gas channeling resistant

联合使用SEP 膨胀 剂和KQ防气窜 剂提高固井质量

Methods Heart protecting musk dispersible tablets were prepared by selecting PVPP as disintegration MCC as filler CMC Ca as sweller and 1 % HPMC solution as adhesive agent .

方法以PVPP为崩解剂、MCC为填充剂、CMCCa为 溶胀性 辅料、 1%HPMC水溶液为粘合剂，制备麝香保心分散片；

This sweller has no negative impacts on other cement slurry and improve the strength of the set cement .

该 膨胀 剂 还对水泥浆的其它性能没有不良影响，对水泥石强度 也 具有一定的改善作用。

The thesis first introduce Cognitive Load Theory advanced by John Sweller then discuss the influences that Intrinsic Cognitive Load in learning materials themselves exert on efficiency of study in class of mathematical learning disability and ability of high school students . The whole research consists of four tests .

本文首先介绍了由 斯 威勒 提出的认知负荷理论，然后探讨了学习材料本身所 具有的内在认知负荷的 大小对高中数学学优生与 学 困生课堂学习效率的影响。
