This idea applies equally in one, two, and a few-dimensional spaces. The whole crystal lattice may be produced by consistently reproducing the pattern of the unit mobile in all directions.

Crystals are beautiful rock formations that have stunned individuals for Countless several years. They may be used for many various things, not just for decoration. Many of the very first radios ever invented employed crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Specific Houses and harmonic abilities of crystals to create highly precise measurements and adjustments.

一般而言，紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅，颜色较深的为A级，稍浅的为B级。一般颜色较深的价格高，但要以不深暗为标准。颜色包括两种，一种是水晶本身的颜色，另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正，分布要均匀，不能太深或太浅，如澳州玉、蓝玉髓、紫晶、黄水晶，其价格就高。无色的水晶内含包裹体的颜色艳丽，其价格也高，如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。

解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。

The weather are observed in a variety of crystal packing preparations. The most common lattice buildings for metals are those obtained by stacking the atomic spheres into one of the most compact arrangement.

Meanwhile, to be certain continued aid, we are exhibiting the positioning without the need of styles and JavaScript.

Solids that have short-array buy but deficiency prolonged-variety purchase are called amorphous. Pretty much any materials might be produced amorphous by quick solidification through the melt (molten condition). This affliction is unstable, and the stable will crystallize in time. In case the timescale for crystallization is years, then the amorphous state seems steady.

16I opened the box and noticed a bit of crystal snowflake and a greeting card with "Content Birthday" within the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。

Crystallography will be the study of crystals, and it promotions check here with almost everything from perfect geometric styles to seemingly random conglomerations of particles and minerals.

《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”

An additional method of crystalline carbon relies with a molecule with 60 carbon atoms called buckminsterfullerene (C60). The molecular shape is spherical. Each individual carbon is bonded to a few neighbours, as in graphite, as well as the spherical shape is realized by a mix of 12 rings with five sides and twenty rings with six sides. Related buildings ended up very first visualized with the American architect R. Buckminster Fuller for geodesic domes.
