17These rings are indicative on the crystal structure of nickel and might be explained only by invoking wavelike Attributes 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。
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。

The sodium chloride crystal lattice is characterised via the shut packing of your optimistic sodium ions and negative chloride ions. Each sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by six sodium ions, making a very stable and symmetrical composition.
This Overview chronicles above two decades of research into creating a genetic code for crystal engineering. Rather then directing Organic procedures, this code utilizes synthetic sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which almost just about every element of the resultant buildings is usually systematically controlled. Inside this conceptual framework, the structural and useful advancements are described in an effort to determine the existing volume of sophistication also to forecast upcoming Instructions with the System.
