看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。
水晶原石观赏石充分体现了天然水晶的本质，经过抛光的水晶原石观赏石，玲珑剔透、晶莹璀璨，独具匠心的设计，恰到好处地显露出水晶的魅力。如果您想单纯的欣赏水晶，水晶原石观赏石是你的不二之选，给人一种返璞归真的感觉。
These advances incorporate unique structures with programmable lattice symmetries and properly-defined crystal practices, responsive components that leverage the intrinsic Houses of nucleic acids to control structures on demand from customers, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that offer insights into light–issue interactions. On the lookout ahead, we obstacle the Group to leverage the incredible structural Management afforded by crystal engineering with DNA to synthesize classes of purposeful products that press outside of what has long been feasible with Normally happening crystalline elements or People created by additional conventional tactics.
诗中道出一段唐代由盛变衰的史实。玄宗末年，杨贵妃得宠，三姐妹并封为国夫人。他们养尊处优，奢华至极，仆人用水晶盘将珍馐佳肴端到宴席上，美人觉得没有口味，懒得动筷子。作为“诗圣”作为“史诗”，紫驼一段写饮食之精美，不空发议论，只尽情揭露事实，无一刺讥语，无一慨叹声，却使人于以外得之：此诗之善讽也。以史为鉴，这样的世道，这样的人物，国家不出“安史之乱”那样的大祸反倒不正常了。
C2 [ U ] clear glass of pretty superior quality, ordinarily with its area Minimize into delicate patterns:
发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
For a incredibly hot Answer cools or a saturated Remedy evaporates, particles draw near enough for chemical bonds to type. Crystals might also kind from deposition directly from the gas period. Liquid crystals possess particles oriented in an organized manner, like strong crystals, but will be able to movement.
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。
Solids which have short-array buy but absence long-assortment buy are called amorphous. Just about any content might be built amorphous by immediate solidification from your soften (molten condition). This ailment is unstable, and the sound will crystallize in time. In case the timescale for crystallization is yrs, then the amorphous condition appears stable.
From your Cambridge English Corpus We say the chain topology from the substantial w location functions as the proverbial ' scratch-on-theglass ' essential while in the natural chemistry laboratory to produce crystals. With the Cambridge English Corpus Consistent-stress and temperature molecular-dynamics simulations of crystals on the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Through the Cambridge English Corpus Along with these, dust particles have been noticed in very low-temperature plasmas, like those used in plasma processing and plasma crystals. In the Cambridge English Corpus The ultimate Portion of the book concentrates on peculiarities of strongly coupled dusty plasmas, like the formation of dust crystals and affiliated desirable forces. With the Cambridge English Corpus Total characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From your Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, primary morphologies were not observed. With the Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from sources online. Any opinions while in the illustrations will not depict the belief of the Cambridge Dictionary editors or of Cambridge College Press or its licensors.
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（growth traces）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
