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。
A basic plan in crystal buildings is the device cell. It's the smallest unit of quantity that permits equivalent cells to generally be arranged collectively to occupy all offered House. The geometrical basis of all crystals is the lattice. A lattice could be viewed as a regular and infinite arrangement of details or atoms, in which Every place or atom has An analogous encompassing environment.
4Without a crystal ball, it's difficult to convey exactly where we will be up coming yr.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
Most sound products present in nature exist in polycrystalline form as an alternative to as an individual crystal. They are literally made up of countless grains (tiny crystals) packed collectively to fill all space. Each individual unique grain has a distinct orientation than its neighbours. Despite the fact that extended-array buy exists inside a person grain, for the boundary amongst grains, the purchasing modifications direction. An average bit of iron or copper (Cu) is polycrystalline.
C2 [ U ] transparent glass of quite top quality, ordinarily with its area Reduce into fragile designs:
Not all crystals sort in h2o, but almost all crystals variety the exact same way, atoms arrive with each other and become a uniformed cluster. The process usually takes as minor as a few days to possibly a thousand decades. Organic crystals that originate from the Earth form a similar way.
Insert to term checklist Add to word list [ C/U ] clear rock that looks like ice, or maybe a piece of it
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
13Nearly all personal computers contain a quartz-crystal clock to manage their Procedure.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。
crystal The recently crystallized quartz grains are characterised by elongate crystals oriented oblique to your shear band margins, defining a typical grain-form foliation. 来自 Cambridge English Corpus We say the chain topology inside the higher w location acts given that the proverbial ' scratch-on-theglass ' wanted in the organic chemistry laboratory for making crystals. 来自 Cambridge English Corpus The click here age scatter among the individual crystals may possibly mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene kinds neutral to pale brown, subhedral to anhedral crystals, from time to time containing inclusions of plagioclase microlaths and opaque phases.
Within the Cambridge English Corpus We are saying the chain topology during the superior w region functions since the proverbial ' scratch-on-theglass ' desired during the organic and natural chemistry laboratory for making crystals. With the Cambridge English Corpus Continual-tension and temperature molecular-dynamics simulations of crystals on the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Through the Cambridge English Corpus Together with these, dust particles happen to be noticed in small-temperature plasmas, like People Employed in plasma processing and plasma crystals. From your Cambridge English Corpus The final Portion of the guide focuses on peculiarities of strongly coupled dusty plasmas, like the development of dust crystals and connected interesting forces. In the Cambridge English Corpus Comprehensive characterization of harm threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. Within the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Major morphologies were not observed. With the Cambridge English Corpus See all examples of crystal These illustrations are from corpora and from sources on the net. Any thoughts from the illustrations usually do not symbolize the viewpoint of your Cambridge Dictionary editors or of Cambridge University Push or its licensors.
Molecular Crystals: Overall molecules are bonded to one another in an arranged manner. A superb example can be a sugar crystal, which contains sucrose molecules.
crystal, any reliable content in which the component atoms are organized in a very definite pattern and whose surface regularity reflects its inside symmetry.
Fig. five: The chance to notice described crystal routines is dependent on the symmetry engineering technique.
