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：
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
Chemical Bonds The categories of chemical bonds fashioned among atoms or groups of atoms in crystals rely upon their dimensions and electronegativity. You'll find 4 categories of crystals as grouped by their bonding:

Lattices can have 1 lattice place per cell or multiple, yielding a complete of 14 Bravais crystal lattice kinds. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array made by a list of discrete points.
Springer Mother nature stays neutral regarding jurisdictional statements in released maps and institutional affiliations.
You will find there's comparable directive about crystal glass which differentiates between complete lead crystal, direct crystal and crystal.
Q.four. What's the distinction between atomic construction and website crystal framework? Ans. The principal difference between atomic composition and crystal structure lies of their definitions: atomic structure refers to how atoms are organized inside a single molecule or maybe a cluster of molecules, Whilst crystal construction considerations the specific arrangement of atoms inside of a reliable material.
