An Unbiased View of Crystal

This concept applies equally in one, two, and 3-dimensional spaces. The complete crystal lattice might be produced by consistently reproducing the pattern of the unit cell in all Instructions.

无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度,越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏,就没有利用价值。

水晶文化历史悠久,古人曾赋予它一串极富美感的雅称:水玉、水精、水碧、石英等。

水碧:《山海经》中,水晶又被称作水碧: �?又南三百里,日耿山,无草木,多水碧 �?,郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用,晋代郭景纯《璞江赋》道�?�?鬼,水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉,水精谓之玉瑛也�?”

There's also many materials that resemble crystals but are actually polycrystals. Polycrystals variety when microscopic crystals fuse together to kind a good. These materials usually do not encompass ordered lattices.

Monoclinic �?Characterized by 3 unequal axes, two of which intersect at an oblique angle, while the third is perpendicular to the airplane of the other two.

水晶内部有多种矿物包裹体,形成的各种景观可以肉眼观测,这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石,因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性,具有极高欣赏和收藏价值。

Ionic Crystals: Electrostatic forces kind ionic bonds. A common case in point is often a halite or salt crystal.

13Nearly all pcs consist of a quartz-crystal clock to control their operation.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。

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。

看孔眼:对于缀穿水晶制品(如项链、手链、佛珠),要看孔眼是否平直,孔的粗细是否均匀,有无细小裂纹。孔壁必须清澈透明,无“白痕”。

Crystallography could be the study of crystals, and check here it promotions with everything from fantastic geometric styles to seemingly random conglomerations of particles and minerals.

水玉:中国最古老的称法叫水玉,意谓似水之玉,又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道:�?水玉簪头白角巾,瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》:�?又东三百里,日堂庭之�?…�?多水�?”;�?丹山出焉,东南流注于洛水,其中多水玉 ”;�?逐水出焉,北流注于渭,其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉,古人是看�?�?其莹如水,其坚如�?�?的质地。

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。
