27Local economists have looked into their crystal balls and witnessed a little something relatively awful.当地的经济学者们已预测到将会出现棘手的问题。《柯林斯英汉双解大词典》
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。
These improvements involve exotic constructions with programmable lattice symmetries and nicely-outlined crystal habits, responsive resources that leverage the intrinsic Homes of nucleic acids to control structures on demand, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that supply insights into mild–make any difference interactions. Looking forward, we problem the community to leverage the amazing structural Handle afforded by crystal engineering with DNA to synthesize classes of practical elements that drive outside of what has been possible with The natural way transpiring crystalline elements or People created by a lot more conventional procedures.
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
There are actually many different crystals depending on geometric structures, crystal development, and content. There is often preparations of hexagonal carbon atoms or amethyst that makes hexagonal pyramid structures.
, has exactly the same framework, but there are two options for selecting the holes that the atoms will occupy. The 3rd layer may be positioned above the atoms of the 1st layer, generating an alternate layer sequence A
Springer Character continues to be neutral with regard to jurisdictional claims in published maps and institutional affiliations.
The weather are discovered in many different crystal packing preparations. The most typical lattice structures for metals are All those obtained by stacking the atomic spheres into quite possibly the most compact arrangement.
仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
16I opened the box and saw a piece of crystal snowflake in addition to a greeting card with "Content Birthday" inside the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。

The structure of the sodium atoms on your own, or the chlorine atoms by yourself, is fcc and defines the unit cell. The sodium chloride framework click here Hence is produced up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) is predicated around the bcc composition; each individual other atom is cesium or chlorine. In such cases, the unit mobile can be a cube. The third vital composition for AB
