8Where can we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球？
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。
10This could be the silicon chip—a little bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Fig. three: A library of lattice symmetries could be accessed by transforming the particle core and DNA shell.
2She was putting on a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》
结晶�?When sea water is allowed to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
Metallic Crystals: Metals usually kind metallic crystals, exactly where a lot of the valence electrons are totally free to maneuver all through the lattice. Iron, such as, can sort diverse metallic crystals.
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
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。
Molecular Crystals: Total molecules are bonded to each other in an structured fashion. A fantastic illustration is really a sugar crystal, which incorporates sucrose molecules.
This Overview chronicles around two decades of analysis into developing a genetic code for crystal engineering. As opposed to directing Organic procedures, this code works by using synthetic sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which just about every element of the resultant constructions is often systematically managed. Inside this conceptual framework, the structural and useful innovations are explained in an effort to outline the present degree of sophistication and to forecast long term more info directions of your platform.
Tetragonal �?Characterized by a few mutually perpendicular axes, two of which can be equal in duration, whilst the third is extended or shorter and perpendicular to another two.
