平行四边形

In Euclidean plane geometry terms, being a parallelogram is : affine transformations always take one parallelogram to another one.

用欧氏平面几何术语，平行就是：仿射变换总是将一个平行四边形变成另一个平行四边形。

Firstly a square image is divided in- to two parts by diagonal and a parallelogram is reformed.

首先沿图像的对角线方向将正方形图分为上下两个部分并重新组合成一个平行四边形的图像；然后利用平行四边形图像的两列像素之间的像素数目差将某列中的像素插入到相邻下一列像素之间。

A solid with six faces, each a parallelogram and each being parallel to the opposite face .

每个底部是边数相同的多面形且其它面是不等边四边形或平行四边形的旁面三角台。

The line that joins the midpoints of the nonparallel sides of a trapezoid.

四个边相等的平行四边形；不是直角的等边平行四边形。

These stars form a parallelogram – a four-sided figure with its opposite sides equally long and parallel to one another.

这些星星组成了一个平行四边形-对边等长且平行的四边形。

A parallelogram with adjacent sides of unequal lengths; an oblique-angled parallelogram with only the opposite sides equal.

相邻的边长度不相等的平行四边形；只有相对的边长度相等的非直角平行四边形。

Methods:To study the changes of contour stresses acted on the rectangle of body system based on the evolution from four-footed animals standing to two-footed human body standing.

脊柱的结构与运动是按平行四边形的轮廓应力达到平衡的。根据Wloff定律，颈曲和腰曲是人类站立后，在平行四边形数学定律作用下形成。

This work presents a unifying framework based on the parallelism constraint, and the previous methods based on the parallelograms or the parallelepipeds can be integrated into this framework.

该工作提供了一个基于平行性约束的框架，以往的基于平行四边形、平行六面体的方法都可以纳入到这个框架中。

The other classification of Double Chain is made of a serious of loop parallelograms, i.e., in the assemblies each set of four neighbouring hinges form a parallelogram.

另一类Double Chain是由一系列的平行四边形组成的，即每一对角单元相互之间的四个剪式铰节点形成平行四边形。

For example, omitting 'right angle' feature brings parallelograms under rectangles. The after called "underexatension" in the study, student can't understand relationship between graphs. For example, students don't think rectangles are one of the parallelograms.

前者往往是学童忽略一项属性的结果，例如忽略直角的特性，就会把斜长的平行四边形归类为长方形，而后者则因学童无法理解图形间包含关系的结果，例如把长方形排除在平行四边形的概念范畴之外。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
