Very clever were some of their productions, pasteboard guitars, antique lampshade of old-fashioned butter boats covered with silver paper, gorgeous robes of old cotton, glittering with tin spangles from a pickle factory, and armor covered with the same useful diamond shaped bits left inn sheets when the lids of preserve pots were cut out. The big chamber was the scene of many innocent revels.

所幸的是&需要是发明之母&，她们制作出来的一些东西也充满了聪明才智——用硬纸板糊起来的吉它，用旧式的船形奶油碟罩上锡纸做成的古色古香的灯罩，用旧棉布做的华丽长袍，上面还点缀着闪闪发光的锡片做的小饰物，而那些小锡片则是从附近的一家腌菜场捡来的，还有用同样闪闪发光的菱形小锡片装饰起来的盔甲，而这样一些菱形的锡片则是腌菜罐的盖子切边时切剩下来的，最后那个大会客厅就是狂欢的大舞台了。

Leaf blade rhombic-obovate or rhombic-elliptic, both surfaces glabrous or abaxially areoles of vein axils sparsely puberulent, lateral veins 2-4 pairs.

The calculated results show that azido in azides has linear structure , the most optimized CaN6 has linear structure , and the most optimized (CaN6)n (n=2～5) clusters have chain structure of perpendicularity of approximate diamond composed by two azido with two Ca atoms . The middle N atoms of azido show positive, the N atoms at both ends of azido show negative, and the N atoms effected with Ca atoms directly show more negative . There is strong ionic bond between the Ca and N atoms. The IR spectra of the most optimized (CaN6)n (n=1～5) clusters have four vibrational sections , the whole strongest vibrational peak lies in 2195～2280cm-1,and the vibrational mode is anti-symmetric stretching vibration of N-N bonds in azido . Stability analysis show that (CaN6)3 and (CaN6)5 clusters are more stable than other clusters .

结果表明，叠氮化合物中叠氮基以直线型存在，CaN6团簇的最稳定结构为线型结构，(CaN6)n(n=2～5)团簇首先由两个叠氮基与两个Ca原子构成一个近似菱形，再由菱形相互垂直形成链状最稳定结构；叠氮基中间的N原子显示正电性，两端的N原子显示负电性，且与Ca直接作用的N原子负电性更强，金属Ca原子和N原子之间形成很强的离子键；(CaN6)n(n=1～5)团簇最稳定结构的IR光谱分为4个部分，其最强振动峰均位于2195～2280cm-1，振动模式为叠氮基中N-N键的反对称伸缩振动；稳定性分析显示，(CaN6)3和(CaN6)5团簇相对于其他团簇较为稳定。

In the Eastern Zhou Dynasty, there are a kind of bronze weapons in the Wu and Yue areas, which have lozenge-shaped pattern on the surface. Archaeologists and scientists have paid much attention to it since seventies.

东周时期，在吴越地区的少数青铜兵器表面上，有一种非机械镶嵌的菱形纹饰，极具装饰性，如在著名的越王勾践剑和吴王夫差矛上，即分布着这种规则的菱形纹。

Research found, generally speaking, students' concept image is not fully covered about quadrilaterals. That is to say, some graph is excluded wrongly. For example:students took oblique square is rhombi, not square. This phenomenon probably caused by they see the typical shape all the time, which will impact the development of the higher level reasoning. Say, students might not be able to understand the inclusion relationship between square and rhombi.

研究发现，学生在四边形几何图形的概念心像上普遍有包含性不足的情况，也就是有些图例被错误地排除（如：以为斜摆的正方形是菱形，但不是正方形），此一现象应与学生接触的通常是典型图例所致，且会影响更高层次的几何推理之发展，例如无法理解正方形与菱形的包含关系。

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。
