A stable is crystalline if it's got lengthy-range buy. After the positions of an atom and its neighbours are regarded at just one point, the place of every atom is understood precisely through the crystal. Most liquids lack extensive-assortment purchase, although quite a few have brief-assortment purchase. Quick variety is described as the primary- or second-nearest neighbours of an atom. In many liquids the first-neighbour atoms are organized in the same composition as from the corresponding sound period.
Bismuth (Bi) seems being a steel, but the number of electrons available for electrical conduction is comparable to that of semiconductors. In fact, bismuth is named a semimetal. Molecular solids are usually crystals shaped from molecules or polymers. They are often insulating, semiconducting, or metallic, dependant upon the style of molecules while in the crystal. New molecules are constantly being synthesized, and several are created into crystals. The volume of distinctive crystals is big.
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
Fig. 7: A template-directed technique can Manage The location of developing blocks on a area from the formation of elaborate structures.
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
Not all crystals variety in water, but nearly all crystals sort a similar way, atoms come alongside one another and become a uniformed cluster. The process might take as minimal as a couple of days to it's possible a thousand years. Organic crystals that come from the Earth sort exactly the same way.
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。

Metallic Crystals: Metals typically form metallic crystals, in which a lot of the valence electrons are cost-free to move all through the lattice. Iron, one example is, can form different metallic crystals.
crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique to your shear band margins, defining a standard grain-condition foliation. 来自 Cambridge English Corpus We are saying the chain topology in the higher w location functions as the proverbial ' scratch-on-theglass ' necessary within the natural and organic chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter among the individual crystals may perhaps 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, at times that contains inclusions of plagioclase microlaths and opaque phases.
From your Cambridge English Corpus We say the chain topology within the significant w location acts given that the proverbial ' scratch-on-theglass ' needed within the natural chemistry laboratory for making crystals. Within the Cambridge English Corpus Frequent-stress and temperature molecular-dynamics simulations of crystals website of the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. In the Cambridge English Corpus As well as these, dust particles happen to be noticed in minimal-temperature plasmas, like These Employed in plasma processing and plasma crystals. From the Cambridge English Corpus The ultimate part of the e book concentrates on peculiarities of strongly coupled dusty plasmas, such as the formation of dust crystals and affiliated appealing forces. With the Cambridge English Corpus Total characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, primary morphologies were not noticed. In the Cambridge English Corpus See all examples of crystal These examples are from corpora and from sources on the net. Any views while in the illustrations usually do not stand for the opinion with the Cambridge Dictionary editors or of Cambridge College Push or its licensors.
Molecular Crystals: Full molecules are bonded to one another within an organized manner. A great illustration is really a sugar crystal, which is made up of sucrose molecules.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
crystal Alteration is variable: absent in many crystals, in others creating dense sericite aggregates which can show some recrystallization consequences to create coarser-grained white mica. With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally organized in aggregates. Through the Cambridge English Corpus Moreover, haloarchaeal cells have been embedded within salt crystals under laboratory problems and subsequently analysed by mild microscopy. In the Cambridge English Corpus The white clouds (ordinarily sparse) were being also broadly thought to be being made up of small crystals of water ice, somewhat like cirrus in our ambiance. In the Cambridge English Corpus They're located in evaporite salt lakes and can be trapped in salt crystals through evaporation. Within the Cambridge English Corpus As a result, the cells (organelles and membranes) are ruined mechanically by ice crystals, leading to death through mobile lysis. With the Cambridge English Corpus The crystals were being Utilized in the very first or 2nd orders of reflection. From your Cambridge English Corpus Within our 8xperiments, the crystals ended up cubes with a foundation spot of eight e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and tension.
