27Local economists have appeared into their crystal balls and observed a thing somewhat terrible.当地的经济学者们已预测到将会出现棘手的问题。《柯林斯英汉双解大词典》
the stable point out of many very simple substances, that have an everyday condition and surfaces arranged in comparable designs
晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Crystalline structure is characterised by a geometrical, repeating pattern of symmetric molecular construction. The arrangement of atoms types these ordered, repeating designs.
Encyclopaedia Britannica's editors oversee issue parts during which they may have comprehensive expertise, no matter if from a long time of working experience acquired by engaged on that material or by using study for a sophisticated degree. They compose new articles and verify and edit content received from contributors.
Springer Character remains neutral with regards to jurisdictional promises in published maps and institutional affiliations.
损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
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 that have shorter-range get but deficiency lengthy-range purchase are named amorphous. Almost any content is often built amorphous by rapid solidification from your soften (molten condition). This condition is unstable, and also the solid will crystallize in time. In the event the timescale for crystallization is a long time, then the amorphous state appears steady.
⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。
隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
This Critique chronicles more than 20 years of investigate into creating a genetic code for crystal engineering. Rather than directing Organic processes, this code makes use of synthetic varieties of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D more info and 3D crystalline architectures, in which just about every single element of the resultant constructions is often systematically managed. Within just this conceptual framework, the structural and functional innovations are described in an effort to define the current amount of sophistication and also to forecast upcoming Instructions from the System.
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。
