8Where do 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？
23Sometimes, even so, the crystal type of the silicate inclusions is noticed to resemble more carefully 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。
4Without a crystal ball, it's impossible to mention where we are going to be subsequent yr.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
Tetragonal: These crystals form prisms and double pyramids. The composition is sort of a cubic crystal, other than one particular axis is for a longer period than another.
Fig. 4: Creating blocks with different shapes and surface area chemistries immediate the development of distinct crystal symmetries.

对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
The definition of the good seems obvious; a good is mostly regarded as currently being tricky and organization. Upon inspection, however, the definition will become significantly less clear-cut. A dice of butter, as an example, is tough just after being stored inside of a refrigerator and it is Evidently a sound. After remaining on the kitchen counter for on a daily basis, precisely the same cube will become fairly comfortable, and it more info is unclear When the butter need to even now be viewed as a good.
The fundamental units of solids are possibly atoms or atoms which have put together into molecules. The electrons of the atom transfer in orbits that kind a shell structure across the nucleus. The shells are filled in a scientific order, with Just about every shell accommodating only a small variety of electrons. Various atoms have diverse quantities of electrons, which can be distributed inside a characteristic electronic framework of filled and partially stuffed shells.
Crystal Lattices There are seven methods of crystal structures, which can be also referred to as lattices or Area lattices:
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。
