Crystals are beautiful rock formations which have amazed human beings for Many years. These are used for quite a few different things, not just for decoration. Many of the 1st radios ever invented utilized crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Unique Houses and harmonic abilities of crystals to make hugely precise measurements and changes.

A crystal composition focuses on how the atoms are organized Within the crystal. However, crystallographers are interested in the overall shape and size of your crystal in addition to its external traits. To perform this, they need to know about the crystal system.

Fig. three: A library of lattice symmetries can be accessed by transforming the particle Main and DNA shell.

. These four buildings comprise most of the binary crystals with equal figures of cations and anions.

当二氧化硅结晶完美时就是水晶；结晶不完美的就是石英：二氧化硅胶化脱水后就是玛瑙；二氧化硅含水的胶体凝固后就成为蛋白石；二氧化硅晶粒小于几微米时，就组成玉髓、燧石、次生石英岩。

30Three days went previous, and I used to be stunned to check out it once again: all of the openings were being sewed up by slim and white thread they usually looked like the ice crystal on winter's branches in the north.

13Nearly all pcs include a quartz-crystal clock to control their operation.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。

Solids that have small-array buy but deficiency lengthy-assortment order are named amorphous. Almost any content may be created amorphous by swift solidification in the melt (molten condition). This problem is unstable, as well as the solid will crystallize in time. If your timescale for crystallization is years, then the amorphous state seems stable.

16I opened the box and observed a bit of crystal snowflake as well as a greeting card with "Happy get more info 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。

水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。

水精：水晶为何称为水精，《广雅》有巧解：�?水之精灵�?”；李时珍则说：�?莹洁晶光，如水之精英 ”。细加考究，此称还蕴含浓厚的宗教意味呢。水精一名，最初见于佛书，后汉支曜翻译的《具光明定意经》说：�?其所行道，色如水�?�?。

One more sort of crystalline carbon is based on a molecule with sixty carbon atoms identified as buckminsterfullerene (C60). The molecular form is spherical. Every single carbon is bonded to three neighbours, as in graphite, as well as spherical condition is reached by a combination of 12 rings with five sides and 20 rings with six sides. Similar buildings were first visualized with the American architect R. Buckminster Fuller for geodesic domes.
