其它描述：《庶物异名疏》中说： �?水精出大秦国，一名黎�?�?。结晶完整的水晶晶体，就如参差交错的马齿，所以人们又叫它马牙石。先民们最早用它研磨成眼镜片，因而送它一个眼镜石的绰号。水晶有通称，也有俗称。广州一带称水晶叫晶玉，又名鱼脑冻；江苏东海县山民发现水晶会 �?窜火�?�?，于是给它起个放光石的俗名。世间一物多名，不足为奇，而像水晶拥有这么多的别称，实不多见。瞧，从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等，简直构成一部奇石鉴赏史。

These advancements consist of exotic structures with programmable lattice symmetries and very well-described crystal practices, responsive materials that leverage the intrinsic Qualities of nucleic acids to control constructions on desire, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals offering insights into gentle–issue interactions. Wanting forward, we obstacle the Group to leverage the amazing structural Regulate afforded by crystal engineering with DNA to synthesize classes of useful elements that drive over and above what is achievable with Normally taking place crystalline resources or those produced by extra regular approaches.
Include to word listing Incorporate to phrase checklist C2 [ U ] clear glass of incredibly high quality, commonly with its surface Slice into sensitive styles
Crystalline framework is characterized by a geometrical, repeating pattern of symmetric molecular construction. The arrangement of atoms sorts these purchased, repeating styles.
Lattices might have one lattice position per cell or multiple, yielding a total of 14 Bravais crystal lattice styles. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the 3-dimensional array produced by a set of discrete points.
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。

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。
The definition of the strong appears evident; a solid is usually considered currently being difficult and business. On inspection, nonetheless, the definition will become a lot less clear-cut. A dice of butter, as an example, is tough soon after being saved in the refrigerator and it is Evidently a stable. Immediately after remaining to the kitchen area counter for every day, the identical cube turns into really comfortable, and it is unclear When the butter ought to still be regarded a sound.

There are actually other minerals and molecules which can kind these crystal lattices. Snowflakes really are a traditional illustration of a approximately symmetric and geometrically patterned composition from ice crystals, and gemstones of all kinds are typically crystals.

Binary crystals are located in numerous structures. Some pairs of elements form more than one structure. At room temperature, cadmium sulfide might crystallize both while in the zinc blende or wurtzite structure. Alumina also has two doable structures at home temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinctive constructions at distinct temperatures. Among the most advanced crystals are People of silicon dioxide (SiO2), which has 7 unique buildings at several temperatures and pressures; the most typical of such constructions is quartz.
