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:
Bismuth (Bi) appears for being a metal, but the number of electrons available for electrical conduction is similar to that of semiconductors. In reality, bismuth is termed a semimetal. Molecular solids are frequently crystals formed from molecules or polymers. They can be insulating, semiconducting, or metallic, depending on the kind of molecules during the crystal. New molecules are consistently getting synthesized, and plenty of are created into crystals. The volume of unique crystals is enormous.
4Without a crystal ball, it's unachievable to state wherever we are going to be subsequent year.不用水晶球预卜未来,我们说不准明年处境如何呀。《牛津词典》
Encyclopaedia Britannica's editors oversee subject matter regions during which they've got substantial understanding, whether from many years of expertise obtained by engaged on that content or through research for an advanced degree. They produce new content and validate and edit content obtained from contributors.
这种水晶观赏石特指水晶晶簇,它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
, has exactly the same structure, but There are 2 decisions for selecting the holes that the atoms will occupy. The 3rd layer is usually placed about the atoms of the 1st layer, making an alternate layer sequence A
光泽:玻璃光泽。断口处为油脂光泽。光泽,指宝石表面对光线反射的一种光学性质。观察水晶的光泽,可用手握着它,以灯光或窗户投进来的光线看表面反射,透明水晶亮度与光泽强弱有关。
Crystals might be developed under moderate ailments from all 92 Obviously occurring components other than helium, and helium is often crystallized at small temperatures by making use of twenty five atmospheres of pressure.
Q.four. What is the distinction between atomic construction and crystal framework? Ans. The primary distinction between atomic structure and crystal framework lies within their definitions: atomic composition refers to how atoms are organized within a one molecule or possibly a cluster of molecules, Whilst crystal construction fears the specific arrangement of atoms within a reliable compound.
22Working from what The united states currently is familiar with about itself, the bureau's gurus and also other demographers provide an irresistible, if clouded, crystal ball among the their visions.

Crystals are classified usually classes, for example insulators, metals, semiconductors, and molecular solids. Just one crystal of an insulator is frequently get more info clear and resembles a piece of glass. Metals are shiny unless they have got rusted. Semiconductors are occasionally shiny and sometimes clear but are by no means rusty. Several crystals can be categorised as only one type of good, while others have intermediate conduct. Cadmium sulfide (CdS) is often organized in pure kind and is an excellent insulator; when impurities are added to cadmium sulfide, it results in being an interesting semiconductor.
