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:
12He tried out once again in several other metropolitan areas and succeeded with Crystal Caramels.他又在其他几个城市再次尝试,并成功制出了水晶焦糖。
A crystal composition focuses on how the atoms are organized Within the crystal. Nevertheless, crystallographers have an interest in the general shape and size on the crystal and also its external traits. To accomplish this, they have to learn about the crystal technique.
Big crystals of diamond are precious gemstones. The crystal has other intriguing Qualities; it's got the highest audio velocity of any stable and is the best conductor of heat. Aside from diamond, the other widespread sort of carbon is graphite, that is a layered content. Every carbon atom has a few coplanar in the vicinity of neighbours, forming an arrangement known as the honeycomb lattice. A few-dimensional graphite crystals are acquired by stacking equivalent layers.
Crystalline construction is characterised by a geometric, repeating pattern of symmetric molecular structure. The arrangement of atoms forms these ordered, repeating designs.

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:
crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique to your shear band margins, defining a standard grain-condition foliation. 来自 Cambridge English Corpus We are saying the chain topology from the substantial w region acts as being read more the proverbial ' scratch-on-theglass ' required from the natural chemistry laboratory to help make crystals. 来自 Cambridge English Corpus The age scatter among the the person crystals may well mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene varieties neutral to pale brown, subhedral to anhedral crystals, at times containing inclusions of plagioclase microlaths and opaque phases.
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值,但是包裹体水晶观赏石经常需要适当打磨抛光,这样更方便观赏水晶内部的包裹体。
There are other minerals and molecules that can sort these crystal lattices. Snowflakes can be a common illustration of a around symmetric and geometrically patterned composition from ice crystals, and gemstones of all kinds are typically crystals.
在透明的水晶中,隐裂纹呈亮晶晶的片状,有时还会有晕彩效应。这些裂纹是水晶在生长过程中,遇到外力挤压而在内部产生的一些隐形裂纹,隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充,形成愈合的裂纹,也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光,都可以在包裹体水晶种找到缩影。
