10This will be the silicon chip—slightly chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
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。

A crystal system refers to the classification of crystals based on the geometric arrangement and symmetry of their lattice constructions. You'll find seven principal crystal programs:
Solitary crystals of metals are delicate and malleable, though polycrystalline metals are more durable and stronger and tend to be more practical industrially. Most polycrystalline components is usually designed into large one crystals after extended heat therapy. In the past blacksmiths would warmth a bit of metallic to make it malleable: warmth helps make a couple of grains develop massive by incorporating smaller ones. The smiths would bend the softened metallic into shape and afterwards pound it awhile; the pounding would make it polycrystalline all over again, expanding its power.
