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：
the reliable condition of numerous straightforward substances, which have an everyday form and surfaces organized in equivalent styles
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
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。
. These four structures comprise most of the binary crystals with equivalent quantities of cations and anions.
Not all crystals kind in drinking water, but almost all crystals variety the same way, atoms come alongside one another and become a uniformed cluster. The procedure can take as tiny as a couple of days to possibly a thousand yrs. Purely natural crystals that originate from the Earth form the same way.
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
Several crystals behave like butter in that they are tricky at minimal temperatures but tender at larger temperatures. These are termed solids in any way temperatures below their melting issue. A doable definition of a solid is really an object that retains its condition if left undisturbed. The pertinent problem is how long the item retains its condition. A hugely viscous fluid retains its shape for one hour but not a year. A stable will have to maintain its condition lengthier than that.
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。

国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。
Crystals are labeled generally groups, for instance insulators, metals, semiconductors, and molecular solids. Only one crystal of an insulator is normally transparent and resembles a piece of glass. Metals are shiny Unless of course they've got rusted. Semiconductors are sometimes shiny and in some cases clear but are hardly ever rusty. A lot of crystals is usually Crystal labeled as a single style of strong, while some have intermediate conduct. Cadmium sulfide (CdS) could be geared up in pure form and is an excellent insulator; when impurities are included to cadmium sulfide, it results in being an interesting semiconductor.
crystal Alteration is variable: absent in many crystals, in Other folks generating dense sericite aggregates which can show some recrystallization consequences to provide coarser-grained white mica. Within the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally arranged in aggregates. In the Cambridge English Corpus On top of that, haloarchaeal cells were being embedded in just salt crystals underneath laboratory conditions and subsequently analysed by gentle microscopy. From your Cambridge English Corpus The white clouds (typically sparse) ended up also extensively thought to be staying composed of very small crystals of h2o ice, fairly like cirrus inside our atmosphere. In the Cambridge English Corpus They are located in evaporite salt lakes and can be trapped in salt crystals through evaporation. In the Cambridge English Corpus Therefore, the cells (organelles and membranes) are ruined mechanically by ice crystals, resulting in Loss of life by cell lysis. With the Cambridge English Corpus The crystals were used in the main or second orders of reflection. From your Cambridge English Corpus Within our 8xperiments, the crystals have been cubes by using a base place of 8 e mm. Within the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : impact of temperature and stress.
