17These rings are indicative of the crystal framework of nickel and might be explained only by invoking wavelike Houses of light.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
12He experimented with again in a number of other towns and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
The purchased interior composition of huge crystals, such as fluorite and quartz demonstrated right here, is reflected inside their geometric designs.
Fig. four: Creating blocks with diverse designs and surface chemistries immediate the formation of distinctive crystal symmetries.
They can ultimately create a wonderful very little uniform cluster of atoms, This is certainly the process of increasing crystals. The greater they will occur with each other, the greater of a development are going to be noticeable to your bare eye. Researchers can identify what mineral These are thinking about by how the crystals kind.

1A crystal chandelier lit the home.一盏水晶吊灯照亮了房间。《柯林斯英汉双解大词典》
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
Solids that have limited-selection order but absence extended-vary purchase are referred to as amorphous. Almost any content is often created amorphous by immediate solidification from the melt (molten condition). This affliction is unstable, as well as the stable will crystallize in time. When the timescale for crystallization is many years, then the amorphous point out seems secure.
There's two these probable periodic arrangements. In each, the main layer has the atoms packed right into a aircraft-triangular lattice in which each atom has 6 quick neighbours. Figure two reveals this arrangement to the atoms labeled A
There are other minerals and molecules that can sort these crystal lattices. Snowflakes undoubtedly are a basic illustration of a approximately symmetric and geometrically patterned construction from ice crystals, and gemstones of all varieties are typically crystals.
⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
The C60 molecules, also referred to as buckyballs, are rather sturdy and almost incompressible. Crystals are formed such which the balls are organized within an fcc lattice which has a a single-nanometre spacing amongst the centres of adjacent balls. The identical C70 molecule has the shape of a rugby ball; C70 molecules also sort an fcc crystal when stacked alongside one another. The good fullerenes sort molecular crystals, with weak binding—supplied by van Crystal der Waals interactions—involving the molecules.
