10This would be the silicon chip—somewhat 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。
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。
结晶�?When sea drinking water is allowed to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。

There's a similar directive about crystal glass which differentiates among full lead crystal, direct crystal and crystal.
Several crystals behave like butter in that they are tough at very low temperatures but smooth at larger temperatures. They may be named solids in the slightest degree temperatures down below their melting level. A possible definition of the strong is an item that retains its shape if still left undisturbed. The pertinent problem is how long the object keeps its shape. A really viscous fluid retains its form for one hour but not a calendar year. A good ought to retain its form longer than that.
A crystal process refers back to the classification of crystals determined by the geometric arrangement and symmetry in their lattice buildings. There are actually 7 principal crystal units:
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
The arrangement of more info an atom’s electrons decides its chemical Qualities. The properties of solids tend to be predictable from your Qualities in their constituent atoms and molecules, and different shell buildings of atoms are hence chargeable for the variety of solids.
