A sound is crystalline if it has long-assortment order. Once the positions of an atom and its neighbours are recognised at one particular level, the spot of every atom is known exactly through the entire crystal. Most liquids absence extended-assortment purchase, Whilst many have short-selection get. Short range is defined as the first- or 2nd-closest neighbours of the atom. In lots of liquids the first-neighbour atoms are arranged in the same composition as during the corresponding stable period.

结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
结晶�?When sea h2o is allowed to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。
For a scorching Remedy cools or perhaps a saturated Remedy evaporates, particles draw near plenty of for chemical bonds to type. Crystals may kind from deposition straight from the gas stage. Liquid crystals have particles oriented within an arranged way, like strong crystals, yet will be able to flow.
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。
Crystals with apparent flat faces are called euhedral crystals, whilst All those lacking described faces are identified as anhedral crystals. Crystals consisting of purchased arrays of atoms that are not normally periodic are known as quasicrystals.
16I opened the box and saw a bit of crystal snowflake plus a greeting card with "Content Birthday" while 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。
Crystallography could be the analyze of crystals, and it discounts with anything from best geometric shapes to seemingly random conglomerations of particles and minerals.
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�?�?。
Binary crystals are present in quite a few constructions. Some pairs of elements kind more than one framework. At home temperature, cadmium sulfide may well crystallize both within the zinc blende or wurtzite construction. Alumina also has two doable buildings at place temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinct buildings at distinct temperatures. Among click here the most elaborate crystals are People of silicon dioxide (SiO2), which has 7 various structures at many temperatures and pressures; the most typical of these structures is quartz.
