This idea applies equally in a single, two, and three-dimensional Areas. The entire crystal lattice is often manufactured by frequently reproducing the pattern on the device mobile in all directions.

23Sometimes, however, the crystal method of the silicate inclusions is noticed to resemble more intently the internal framework of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。

看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。

诗中道出一段唐代由盛变衰的史实。玄宗末年，杨贵妃得宠，三姐妹并封为国夫人。他们养尊处优，奢华至极，仆人用水晶盘将珍馐佳肴端到宴席上，美人觉得没有口味，懒得动筷子。作为“诗圣”作为“史诗”，紫驼一段写饮食之精美，不空发议论，只尽情揭露事实，无一刺讥语，无一慨叹声，却使人于以外得之：此诗之善讽也。以史为鉴，这样的世道，这样的人物，国家不出“安史之乱”那样的大祸反倒不正常了。

Fig. four: Making blocks with diverse shapes and surface chemistries immediate the formation of unique crystal symmetries.

Learn the way The form in the crystals decide the various minerals into familiesMinerals crystallize according to one of 7 motifs, often known as crystal programs.

水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。

crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique to the shear band margins, defining a typical grain-form foliation. 来自 Cambridge English Corpus We say read more the chain topology while in the high w area acts as being the proverbial ' scratch-on-theglass ' required in the organic and natural chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter among the person crystals may possibly replicate incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, at times made up of inclusions of plagioclase microlaths and opaque phases.

. The second layer is shaded in the determine. It's the exact same airplane-triangular framework; the atoms sit in the holes fashioned by the main layer. The 1st layer has two equivalent sets of holes, although the atoms of the 2nd layer can occupy only one established. The 3rd layer, labeled C

国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。

Crystals are labeled on the whole groups, like insulators, metals, semiconductors, and molecular solids. Just one crystal of the insulator will likely be clear and resembles a bit of glass. Metals are shiny Until they may have rusted. Semiconductors are sometimes shiny and often transparent but are in no way rusty. Quite a few crystals is usually categorized as just one type of strong, while others have intermediate behaviour. Cadmium sulfide (CdS) is often geared up in pure variety and is a superb insulator; when impurities are added to cadmium sulfide, it becomes a fascinating semiconductor.

矿物成分：针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶，如发晶、钛晶、绿幽灵等，发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶；含铁�?；呈金黄色或柠檬�?)称黄水晶；含锰和钛呈玫瑰色者称蔷薇石英，即粉水晶；烟色者称烟水晶；褐色者称茶晶；黑色透明者称为墨晶。
