He suggested that bees which make hexagonal cells evolved in steps from bees that made round cells, under pressure from natural selection to economise wax.

他认为，建筑六角形蜂房的蜜蜂是从建筑圆形蜂房的蜜蜂进化而来；是在节省蜡的自然选择压力下的几个进化阶段形成的。

This problem dates back to 1611, when Johannes Kepler conjectured that the best packing arrangement for identical spheres was arranging them in what is now called face centered cubic packing - similar to how one sees cannon balls stacked.

这个问题可追溯到1611年约翰尼斯·开普勒提出堆积等大球体最佳方法的猜想（译者注：当等大球体按照--球心位于正方体各面的中心上--的形式，并且将第一层摆放成六角形时，它们占用的空间最小，对空间的利用率可以超过74%），现在把这个方法叫做面心立体堆积法--类似于加农炮弹的堆积方式。1998年，安娜堡密西根大学教授托马斯·C·黑尔斯证明了这个猜想。

Probe 探查,查明 diameter 直径半径 radius,semidiameter "This is for deep space observation," said Hitesh Gajjar, an electrical engineer involved in the project, as he pointed with pride at SALT -- a massive hexagon filled with 91 smaller mirrored hexagons, of which 18 are in place.

SALT由18个以91个小六角形镜组成的大型六角镜所构成，Hitesh Gajjar，作为工程的电子工程师，在提到SALT的时候充满自豪地说：它将被用于外层空间的观察。

The most impressive one is that I've hand sharpened the edges so that it presents a period edge geometry, instead of the original thick secondary bevels from the swordsmith.

Stainless steel formed into long shapes from billets. They can be rounds, squares, hexagons, octagons or flats, either hot or cold finished.

不锈钢是由小胚制成长条状的，它们可以是圆形的、方形的、六角形、八角形或平面，热磨光或冷磨光。

Also the hexagonal screw shafts are made of treated tool steel for optimum stiffness and high torque applications.

同样六角形螺杆轴也由经处理的工具钢制成来获得优化的硬度并符合高扭矩应用的需要。

His examples included two he had investigated experimentally: slave-making ants and the construction of hexagonal cells by honey bees.

包括了两个他曾经进行了实验调查的例子：有奴役习性的蚂蚁和建筑六角形蜂房的蜜蜂。

The object of the game (which is a little like "Tetris") is to line up sets of five or more six-sided crystals of the same color before the new crystals fill the screen.

HexaFun 是一个六角形框架的蜂窝方格所组成的宝石宾果游戏，看似简单，但它会随机的在画面中出现下一组宝石，玩家可以用来测试自己的反应能力。
