17These rings are indicative on the crystal framework of nickel and may be defined only by invoking wavelike properties 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。

杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。

A crystal construction concentrates on how the atoms are organized inside the crystal. Nonetheless, crystallographers are interested in the general condition and sizing of your crystal and its external properties. To perform this, they should understand about the crystal system.

市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。

13Nearly all computers consist of a quartz-crystal clock to manage their Procedure.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。

crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique to your shear band margins, defining an average grain-form foliation. 来自 Cambridge English Corpus We say the chain topology in the high w location functions as being the proverbial ' scratch-on-theglass ' needed inside the organic chemistry laboratory to help make crystals. 来自 Cambridge English Corpus The age scatter amongst the person crystals may possibly reflect incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene types neutral to pale brown, subhedral to anhedral crystals, once in a while containing inclusions of plagioclase microlaths and opaque phases.

Solitary crystals of metals are delicate and malleable, even though polycrystalline metals are more durable and much better and tend to be more valuable industrially. Most polycrystalline resources may be manufactured into huge single click here crystals right after prolonged warmth treatment method. Before blacksmiths would heat a bit of metal to really make it malleable: heat can make a couple of grains grow significant by incorporating more compact types. The smiths would bend the softened metallic into condition then pound it awhile; the pounding would allow it to be polycrystalline again, rising its power.

玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。

水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
