17These rings are indicative of your crystal structure of nickel and may be discussed only by invoking wavelike Qualities of sunshine.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) seems being a metallic, but the number of electrons accessible for electrical conduction is analogous to that of semiconductors. In reality, bismuth is referred to as a semimetal. Molecular solids are usually crystals formed from molecules or polymers. They are often insulating, semiconducting, or metallic, with regards to the kind of molecules within the crystal. New molecules are continually currently being synthesized, and plenty of are created into crystals. The volume of different crystals is enormous.
10This would be the silicon chip—slightly chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
We've written about in excess of 300 stones from the mineral kingdom! Examine each stone's unique origin, heritage, and energies down below.
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
Monoclinic �?Characterized by 3 unequal axes, two of which intersect at an oblique angle, even though the third is perpendicular on the airplane of one other two.
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。

A crystal procedure refers back to the classification of crystals according to the geometric arrangement and symmetry of their lattice structures. You can find seven main crystal programs:
say cheese something which someone that is getting a photograph of you informs you to state so that the mouth makes The form of a smile
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。
The composition of your sodium atoms by yourself, or perhaps the chlorine atoms by itself, is fcc and defines the device mobile. The sodium chloride construction thus is built up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) relies over the bcc composition; each individual other atom is cesium or chlorine. In this case, the unit cell is actually a dice. The third significant structure for AB
Binary crystals are located in quite a few buildings. Some pairs of components type more than one framework. At room temperature, cadmium sulfide may crystallize both while in the zinc blende or wurtzite structure. Alumina also has two feasible buildings at home temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinct structures at various temperatures. One of the most advanced crystals are those of silicon dioxide (SiO2), that has 7 distinct constructions at numerous temperatures and pressures; the most common of these buildings is quartz.
