17These rings are indicative of the crystal composition of nickel and might be discussed only by invoking wavelike Homes 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。
12He tried out yet again in numerous other cities and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
A crystal construction focuses on how the atoms are arranged inside the crystal. Nevertheless, crystallographers have an interest in the general shape and measurement of your crystal in addition to its external features. To accomplish this, they need to know about the crystal technique.
We've written about around three hundred stones from the mineral kingdom! Read about Every stone's exceptional origin, historical past, and energies below.
Crystalline composition is characterised by a geometrical, repeating sample of symmetric molecular framework. The arrangement of atoms sorts these purchased, repeating patterns.
Monoclinic �?Characterised by 3 unequal axes, two of which intersect at an oblique angle, although the third is perpendicular to your airplane of one other two.

②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。

⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
Fig. one: Schematic of crystal formation from making blocks composed of a particle Main as well as a shell of Crystal DNA ligands connected on the particle surface area.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
The C60 molecules, also known as buckyballs, are very robust and Nearly incompressible. Crystals are formed these types of the balls are arranged in an fcc lattice with a a person-nanometre spacing among the centres of adjacent balls. The identical C70 molecule has the shape of a rugby ball; C70 molecules also form an fcc crystal when stacked together. The stable fullerenes form molecular crystals, with weak binding—furnished by van der Waals interactions—amongst the molecules.
