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：
One more entertaining, and tasty, experiment will be to form massive crystals using sugar. By heating sugar with h2o and then letting this Alternative evaporate on sticks, you can sort rock candy from sugar crystals!

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：
Solids that have brief-array buy but absence prolonged-vary purchase are termed amorphous. Pretty much any materials is usually produced amorphous by rapid solidification through the soften (molten state). This issue is unstable, and also the reliable will crystallize in time. Should the timescale for crystallization is yrs, then the amorphous state seems secure.
With the Cambridge English Corpus We are saying the chain topology within the higher w area functions as being the proverbial ' scratch-on-theglass ' wanted within the natural and organic chemistry laboratory to produce crystals. In the Cambridge English Corpus Regular-pressure and temperature molecular-dynamics simulations of crystals in the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From the Cambridge English Corpus Together with these, dust particles are already observed in lower-temperature plasmas, like Individuals Utilized in plasma processing and plasma crystals. With the Cambridge English Corpus The final Section of the ebook concentrates on peculiarities of strongly website coupled dusty plasmas, including the development of dust crystals and involved interesting forces. From the Cambridge English Corpus Total characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. In the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, Principal morphologies were not noticed. Through the Cambridge English Corpus See all samples of crystal These examples are from corpora and from resources online.
