诗中“胜美玉”,“过冰清”,写出水晶的质地美,而“亦欲应时明”则描绘出水晶充满灵性的动态美,耐人寻味。罗维是有独特眼光,懂得水晶真谛,第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实;以水晶为直接吟咏对象的诗篇还有:
③、粗抛光:是将模具压出之毛胚,以金刚石盘直接磨出成品之刻线。④、细抛光:在粗抛光之后,以抛光粉来磨成品至晶莹剔透为止。
These improvements involve exotic constructions with programmable lattice symmetries and perfectly-described crystal behaviors, responsive materials that leverage the intrinsic Qualities of nucleic acids to manipulate buildings on demand from customers, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals which provide insights into light-weight–make a difference interactions. Wanting forward, we problem the Local community to leverage the remarkable structural Command afforded by crystal engineering with DNA to synthesize lessons of useful elements that drive past what has actually been probable with Obviously transpiring crystalline materials or People made by more common 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。
断口:贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂,破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
These examples are from corpora and from sources on the internet. Any views in the examples never represent the view from the Cambridge Dictionary editors or of Cambridge College Push or its licensors.
30Three times went past, and I was amazed to find out it once more: many of the openings had been sewed up by slim and white thread plus they looked such as ice crystal on winter's branches in the north.
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。
第三种是“皮景”,因某些其他的矿物与水晶体共生,或由于其他的物质侵蚀而依附于水晶表面,或者是水晶受自然环境的影响,在水晶表面出现蚀象,形成了一些景象或图案,这种景观存在于水晶表面。
crystal The freshly crystallized quartz grains are characterized by elongate crystals oriented oblique for the shear band margins, defining a normal grain-shape foliation. 来自 Cambridge English Corpus We are saying the chain topology from the significant w area acts because the proverbial ' scratch-on-theglass ' essential in the natural and organic chemistry laboratory to make crystals. 来自 Cambridge English Corpus The age scatter amid the person crystals could mirror incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, often that contains inclusions of plagioclase microlaths and opaque phases.

Molecular Crystals: Complete molecules are bonded to one another in an structured method. A superb example is usually a sugar crystal, which contains sucrose molecules.
⑦双色水晶:一种紫色和黄色共存一体的水晶,紫色、黄色之间界限较明显,分别占据晶块的一部分。
水晶观赏石是天然水晶中最具代表的作品,具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值,而水晶观赏石只需要将表面进行抛光,即展现出晶体内所包裹的物质,直接欣赏原汁原味的水晶石。
