17These rings are indicative in the crystal framework of nickel and will be discussed only by invoking wavelike Homes 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。
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。

You can also find quite a few materials that resemble crystals but are literally polycrystals. Polycrystals sort when microscopic crystals fuse together to variety a solid. These resources never include purchased lattices.
Monoclinic �?Characterized by a few unequal axes, two of which intersect at an oblique angle, whilst the 3rd is perpendicular to your airplane of the opposite two.

11I thoroughly opened the check here offer and found a crystal bell inside.我小心地打开包裹，发现里面有一个水晶钟。
Among the binary crystals, the easiest buildings to visualise are These with equivalent numbers of The 2 sorts of atoms. The structure of sodium chloride is predicated over a cube. To build the lattice, the sodium and chlorine atoms are put on alternate corners of a cube, plus the composition is repeated (Figure 3B).
晶体 Silicon crystals developed within a laboratory transform light into electrical energy. 在实验室中长成的硅晶体可将光线转变为电能。
say cheese something which somebody that is getting a photograph of you lets you know to convey so that the mouth would make the shape of the smile
Orthorhombic: They are rhombic prisms and dipyramids that resemble tetragons but with no square cross-sections.
⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
