17These rings are indicative on the crystal composition of nickel and may be explained only by invoking wavelike Houses of light.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。
Crystals are wonderful rock formations which have amazed human beings for A huge number of years. They can be used for numerous various things, not only for decoration. Most of the 1st radios at any time invented made use of crystals to transmit the radio waves. Some instruments, like quartz watches and laser crystals, use Distinctive Houses and harmonic capabilities of crystals to create hugely precise measurements and changes.
A primary notion in crystal structures will be the unit mobile. It's the smallest unit of volume that permits identical cells for being stacked collectively to fill all Place. By repeating the sample from the unit cell again and again in all Instructions, your entire crystal lattice could be constructed. A cube is the simplest illustration of a unit mobile. Two other examples are revealed in Determine 1. The Crystal 1st would be the unit mobile for the facial area-centred cubic lattice, and the next is for just a body-centred cubic lattice. These structures are explained in the next paragraphs.
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。
解理：无解理。所谓解理是指矿物被打击时，沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类：极完全解理、完全解理、中等解理、不完全解理和无解理，水晶属于无解理。
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。
Meanwhile, to be certain continued assist, we're exhibiting the internet site without variations and JavaScript.
晶体 Silicon crystals developed in the laboratory convert gentle into electrical Vitality. 在实验室中长成的硅晶体可将光线转变为电能。

水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
The C60 molecules, also called buckyballs, are rather powerful and almost incompressible. Crystals are fashioned these types of that the balls are organized in an fcc lattice having a one-nanometre spacing amongst the centres of adjacent balls. The comparable C70 molecule has The form of a rugby ball; C70 molecules also type an fcc crystal when stacked with each other. The reliable fullerenes kind molecular crystals, with weak binding—furnished by van der Waals interactions—between the molecules.
