十五边形

The results indicate that the foamed metals have the structure of dodecahedron with pentagonum casement toward space outspread. The framework self is the tube shape channels, which are cavate and nonentirely sealing. The whole framework is a maze structure connecting by this kind of channels. Folds and hollows besprinkle the surface of foamed nickel skeleton.

结果表明用本文方法制备的发泡金属是一种向空间延伸的具有五边形窗的十二面体结构，发泡金属骨架本身是中空的、非完全封闭式的管状"通道"，整个骨架就是由这种"通道"连接的"迷宫"式的结构。

On the basis of the frame of dodecahedron, we apply the method of "spherical stretching" to the frame, we can obtain a novel polyhedron with I_h symmetry, which contains 72 pentagons.

我们在十二面体框架的基础上，利用"球面拉伸"的方法，得到新的具有二十面体对称性，72个五边形构造的的多面体结构。

Its occurrence in regular pentagons and decagons was duly observed, as well as in the dodecahedron (a regular polyhedron whose twelve faces are regular pentagons).

它出现在正五边形和正十边形以及正12面体（一种规则多面体，它的每个面都是正五边形）中是易于观察到的。

Papovaviruses are also icosahedral symmetry viruses, but their capsid structures disobey the quasi-equivalence theory. Papovaviruse capsids are all composed of pentagons. Furthermore, these pentagons can not be connected directly, because there is a certain distance among them.

乳多空病毒尽管也是二十面体对称的病毒，但其衣壳结构违背了准等价原理，它们全是由五边形构建的几何实体，而且奇妙的是这些五边形不能直接拼接在一起，相互间存在一定的距离间隔。

The truncated icosahedra have been prepared for the first time by prolonging the reaction time to 4 h.The XRD,SEM,TEM and Uv-vis technologies confirm the high shape difference between icosahedral gold nanocrystals and their truncated forms.

通过延长反应时间合成了一种类似足球的新型金纳米粒子—截角二十面体，研究结果表明，该粒子由二十个六边形和十二个五边形组成，截角面是{100}面。

On the basis of the frame of dodecahedron, we apply the method of "spherical stretching" to the frame, we can obtain a novel polyhedron with I_h symmetry, which contains 72 pentagons.

A great number of viruses' capsid proteins are efficient assembly into icosahedral symmetry structures. The capsid structures obey the quasi-equivalence theory of Caspar-Klug, and they are directly composed of pentagons and hexagons.

摘 要 绝大多数病毒的衣壳蛋白装配成二十面体对称的结构，其衣壳结构遵从 Caspar-Klug 的准等价原理，即是由五边形和六边形直接拼接而成的几何构型。

Most crystals have six-sided symmetry, though three- or 12-sided snow crystals also fall. You will never see a real snow crystal with four, five or eight sides.

多数晶体呈对称的六边形，尽管有过三角形和十二边形的雪花，但现实中你绝不可能见到四边形、五边形或八角形的雪晶。

By using competitive adsorption of activated carbom to remove unfavorable influence of carbon in carbonaceous gold concentrate on leaching process, the leaching rate of gold concentrate can be improved to 88% as compared with 10%by direct cyanidation.

本文论述了利用活性炭竞争吸附作用，消除含炭金精矿中炭在浸出过程中的影响，使金精矿的浸出率可由直接氰化的10％提高到88％。

The only thing you're ever gonna be king of is King of the Stupids!
