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 good state of numerous simple substances, which have a daily condition and surfaces organized in comparable patterns
结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
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。
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：
晶体 Silicon crystals developed within a laboratory change mild into electrical Strength. 在实验室中长成的硅晶体可将光线转变为电能。
say cheese a thing that a person who is taking a photograph of you lets you know to convey so that the mouth would make the shape of the smile
Crystallography is definitely the study of crystals, and it deals with almost everything from excellent geometric styles to seemingly random conglomerations of particles and minerals.

crystal Alteration is variable: absent in many crystals, in Other people generating dense sericite aggregates which can exhibit some recrystallization effects to produce coarser-grained white mica. Through the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally organized in aggregates. From the Cambridge English Corpus In addition, haloarchaeal cells had been embedded inside salt crystals under laboratory ailments and subsequently analysed by gentle microscopy. Within the Cambridge English Corpus The white clouds (commonly sparse) had been also commonly considered staying made up of small crystals of drinking water ice, somewhat like cirrus in our ambiance. In the Cambridge get more info English Corpus They are found in evaporite salt lakes and might be trapped in salt crystals in the course of evaporation. With the Cambridge English Corpus Thus, the cells (organelles and membranes) are ruined mechanically by ice crystals, bringing about death through mobile lysis. Through the Cambridge English Corpus The crystals ended up used in the primary or second orders of reflection. From your Cambridge English Corpus In our 8xperiments, the crystals had been cubes that has a foundation place of eight e mm. From your Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : result of temperature and stress.
