17These rings are indicative in the crystal structure of nickel and can be spelled out only by invoking wavelike Qualities 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。

Bismuth (Bi) appears to become a metal, but the number of electrons accessible for electrical conduction is similar to that of semiconductors. In truth, bismuth is termed a semimetal. Molecular solids usually are crystals fashioned from molecules or polymers. They are often insulating, semiconducting, or metallic, according to the form of molecules while in the crystal. New molecules are consistently becoming synthesized, and plenty of are created into crystals. The volume of distinctive crystals is gigantic.

10This would be the silicon chip—a bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。

③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。

Crystalline construction is characterized by a geometrical, repeating sample of symmetric molecular structure. The arrangement of atoms types these purchased, repeating designs.

They can ultimately come up with a awesome tiny uniform cluster of atoms, This can be the whole process of expanding crystals. The more they could appear with each other, the greater of a formation will be noticeable on the naked eye. Researchers can ascertain what mineral they are checking out by how the crystals type.

对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。

②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。

Several crystals behave like butter in that they're tough at very low temperatures but tender at increased temperatures. They can be named solids in the least temperatures below their melting position. A probable definition of a stable is definitely an item that retains its form if remaining undisturbed. The pertinent issue is just how long the thing keeps its condition. A very viscous fluid retains its form for one hour but not a year. A sound must hold its condition for a longer time than that.

晶体 Silicon crystals grown within a laboratory convert light into electrical energy. 在实验室中长成的硅晶体可将光线转变为电能。

15The trick to a good thermoelectric substance is a crystal structure during which electrons can movement freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。

水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。

水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。

Binary crystals are present in a lot of constructions. Some pairs of factors type multiple composition. At home temperature, cadmium sulfide may perhaps crystallize possibly from the zinc blende or wurtzite framework. Alumina also has two doable buildings at home temperature, α-alumina (corundum) and β-alumina. Other binary crystals show diverse structures at various temperatures. Among the most complex crystals are Those people of silicon dioxide (SiO2), which has seven unique structures at a variety of temperatures and pressures; the most common of these constructions here is quartz.
