These crystals were formed around 1,000,000 decades in the past inside the Earth's crust. They occur if the liquid inside the Earth consolidates and the temperature chills. Other crystals variety if the liquid makes its way throughout the clefts and dispense minerals in to the clefts.
①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
10This is definitely the silicon chip—slightly chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
We have penned about over 300 stones inside the mineral kingdom! Examine Every stone's one of a kind origin, historical past, and energies down below.
C2 [ U ] transparent glass of really superior quality, ordinarily with its surface Minimize into fragile patterns:
Not all crystals type in drinking water, but almost all crystals kind the exact same way, atoms occur alongside one another and turn into a uniformed cluster. The method usually takes as tiny as a couple of days to maybe a thousand several years. Organic crystals that originate more info from the Earth sort the same way.
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
Metallic Crystals: Metals typically sort metallic crystals, wherever some of the valence electrons are totally free to maneuver through the entire lattice. Iron, for example, can variety distinctive metallic crystals.
[ C/U ] transparent glass of top quality, ordinarily with its area Lower into designs that reflect mild
16I opened the box and observed a piece of crystal snowflake along with a greeting card with "Pleased Birthday" in 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。
隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
14For case in point, We have now Quartz crystal clocks and watches correct to within just 1 minute a 12 months.例如，我们使用的每年误差不超过one分钟的石英水晶钟表和手表。
Fig. five: A chance to realize described crystal patterns is dependent on the symmetry engineering method.
