8Where will 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?

12He tried out once more in several other towns 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。

一般而言,紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅,颜色较深的为A级,稍浅的为B级。一般颜色较深的价格高,但要以不深暗为标准。颜色包括两种,一种是水晶本身的颜色,另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正,分布要均匀,不能太深或太浅,如澳州玉、蓝玉髓、紫晶、黄水晶,其价格就高。无色的水晶内含包裹体的颜色艳丽,其价格也高,如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。

Tetragonal: These crystals variety prisms and double pyramids. The composition is sort of a cubic crystal, other than one axis is lengthier than another.

看抛光:抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。

结晶�?When sea h2o is permitted to evaporate, salt crystals are deposited. 海水蒸发后,盐的结晶体就沉淀下来。

水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见,所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人,所以通常人们会要求水晶净度越高越好,尽量避免有较明显的内含物的水晶。

Hexagonal �?Characterized by four axes, 3 of which are equal in size and intersect at 120 levels, with a fourth axis perpendicular to another a few.

水晶是有成色等级之分,影响水晶价位的因素很多,不像钻石以4C就可以判定,所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好,越透越好,颜色越娇嫩越好,形状越典型越好。不过最重要还是自己喜欢,而选购时辨识真伪的方法大致有下列几种:

The definition of the strong seems apparent; a solid is generally regarded as being really hard and firm. On inspection, nonetheless, the definition becomes considerably less clear-cut. A cube of butter, such as, is difficult right after currently being saved within a fridge and is particularly Obviously a good. Following remaining about the kitchen area counter for per day, the exact same cube turns into fairly gentle, and it really is unclear In the event the butter really should continue to be thought of a strong.

15The trick to a fantastic thermoelectric materials is a crystal composition where electrons can movement freely.制造一种好的热电材料的关键是,需要一种电子可以自由流动的晶体结构。

The sodium chloride crystal lattice is characterised by the shut packing with the constructive sodium ions and negative chloride ions. Each individual sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by 6 sodium ions, making a hugely stable and symmetrical structure.

This Evaluation chronicles around 20 years of exploration into creating a genetic code for crystal engineering. As opposed to directing Organic processes, this code makes use of artificial varieties of DNA website to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which just about every single facet of the resultant buildings can be systematically managed. Inside this conceptual framework, the structural and purposeful advances are explained in order to outline the present level of sophistication also to predict future directions of your System.

This crystal framework is chargeable for the distinctive Bodily and chemical Homes of sodium chloride, which include its large melting position, electrical conductivity, and skill to sort ionic bonds quickly.
