四边形的

In the case of non-regularity meshes, the quasi-Wilson element for arbitrary narrow quadrilateral are studied in this paper.

本文在非正则剖分条件下，研究了任意窄四边形上的类Wilson元。

Based on the construction of reference ele ment and bilinear transformation, a quasi-Wilson element for arbitrary narrow q uadrilateral is presented.

基于参考元的构造和双线性变换，本文给出了一个任意窄四边形类Wilson元。

Secondly, for the boundary correspondence of affine stretch on hyperbolic regions, we prove that the above conclusion is also true. Finally, we pose a sufficient and necessary condition for the same conclusion.

最后利用退化的四边形序列，给出了拟对称同胚的极值拟共形延拓的最大伸缩商、四边形模之比的上确界及拟对称同胚的边界伸缩商三者相等的一个充要条件。

In the Chapter 2, we consider domain decomposition methods for quadrilateral elements.

在第二章中，我们研究四边形元的区域分解方法。

A new type of exoskeleton mechanism has been developed by combination of parallelogram link and gear.

利用平行四边形连杆和齿轮的组合设计了一种外骨骼机构。

The researcher finds that with the analysis of the process of activities, the conduction of the games assist junior one students in clearing the misunderstanding of the different definitions, characteristics and qualities of quadrilaterals. Furthermore, it actively constructs and recognizes the notions of "parallelograms include squars, rectangles and rhombuses". In the end, the researcher proposes the adoptable organic solution to "rectangles include squars","rhombuses include squars" and "squars are the overlapping of rectangles and rhombuses" during the process of activities in the suggestion.

最后，经过研究者对活动历程的分析发现，透过此游戏的进行，协助了国一学生厘清对不同四边形定义、特徵与性质的迷思概念，并主动以非形式推论的方式建构且理解「正方形、长方形、菱形均包含於平行四边形中」，至於「正方形包含於长方形」、「正方形包含於菱形」与「长方形与菱形共同会包含到的图形是正方形」的概念，研究者在本文的反思与建议中，亦提出了活动历程中可采取的机制方法。

The Practice Evaluation of Quadrilateral Concept for Elementary School Students, a book designed by the researcher of this study, will be a tool in evaluating middle- and high-graders' concept and degree of cognition about quadrilaterals.

采用自编的「国小学生四边形几何概念实作评量」为研究工具，探讨国小中、高年级学生四边形几何概念的认知情形及层次，并藉由模糊取向的认知结构分析了解学生的概念结构。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
