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：
Crystals are wonderful rock formations that have surprised individuals for 1000s of many years. They can be utilized for numerous different things, not just for decoration. Lots of the 1st radios at any time invented utilized crystals to transmit the radio waves. Some instruments, like quartz watches and laser crystals, use Specific Houses and harmonic abilities of crystals to help make remarkably precise measurements and changes.
A basic principle in crystal structures will be the unit mobile. It is the smallest unit of quantity that allows identical cells being stacked collectively to fill all space. By repeating the pattern of the device mobile repeatedly in all directions, your complete crystal lattice might be manufactured. A cube is the simplest example of a device cell. Two other illustrations are proven in Determine 1. The first would be the unit cell for any face-centred cubic lattice, and the next is for your overall body-centred cubic lattice. These constructions are discussed in the next paragraphs.
Large crystals of diamond are important gemstones. The crystal has other exciting Qualities; it has the highest audio velocity of any good and is the best conductor more info of heat. In addition to diamond, one other typical type of carbon is graphite, and that is a layered material. Just about every carbon atom has three coplanar in close proximity to neighbours, forming an arrangement known as the honeycomb lattice. A few-dimensional graphite crystals are acquired by stacking related levels.
Fig. four: Creating blocks with diverse designs and surface area chemistries immediate the development of distinct crystal symmetries.

水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。

The definition of a solid seems obvious; a sound is mostly thought of as remaining difficult and company. Upon inspection, even so, the definition will become a lot less straightforward. A dice of butter, as an example, is difficult following staying stored in the refrigerator and is also Obviously a sound. After remaining within the kitchen counter for per day, the same cube results in being quite gentle, and it truly is unclear If your butter need to nonetheless be thought of a stable.
16I opened the box and noticed a piece of crystal snowflake and also a greeting card with "Delighted Birthday" inside the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
Molecular Crystals: Total molecules are bonded to one another within an organized way. A superb illustration is a sugar crystal, which is made up of sucrose molecules.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
