17These rings are indicative from the crystal composition of nickel and may be spelled out only by invoking wavelike Houses of sunshine.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
A crystal composition focuses on how the atoms are arranged Within the crystal. However, crystallographers have an interest in the overall condition and dimension with the crystal and also its external qualities. To accomplish this, they should find out about the crystal program.
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。
Not all crystals kind in drinking water, but nearly all crystals form the same way, atoms come alongside one another and turn into a uniformed cluster. The process might take as minimal as a couple of days to perhaps a thousand several years. Natural crystals that originate from the Earth variety the same way.
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
The weather are observed in a variety of crystal packing arrangements. The most common lattice structures for metals are those obtained by stacking the atomic spheres into one of the most compact arrangement.
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：
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。
The sodium chloride crystal lattice is characterised because of the close packing on the beneficial sodium ions and destructive chloride ions. Each individual sodium ion is surrounded by 6 chloride ions, and every chloride ion is surrounded by six sodium ions, creating a extremely steady and symmetrical construction.
crystal, any reliable material by which the element atoms are arranged inside a definite sample and whose area regularity demonstrates its inner symmetry.
This crystal structure is chargeable for the special physical and chemical Homes of sodium chloride, which include get more info its substantial melting place, electrical conductivity, and ability to form ionic bonds quickly.
