17These rings are indicative in the crystal structure of nickel and can be discussed only by invoking wavelike Attributes of sunshine.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
23Sometimes, even so, the crystal type of the silicate inclusions is observed to resemble far more intently The inner composition 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。
发晶的价值取决于发的颜色、罕见性及大小，一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态，便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值，通过它们可了解几百万年前地球上水的成分及变化。
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。
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。
Encyclopaedia Britannica's editors oversee matter spots in which they have got considerable awareness, no matter if from a long time of working experience acquired by working on that content material or by using research for a complicated diploma. They generate new content and verify and edit content material acquired from contributors.
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。
11I thoroughly opened the bundle and found a crystal bell inside of.我小心地打开包裹，发现里面有一个水晶钟。
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：
英语-中文（简体） phrase #beta Beta /beta #preferredDictionaries ^selected identify /chosen /preferredDictionaries
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
This Evaluate chronicles in excess of twenty years of study into developing a genetic code for crystal engineering. Rather than directing Organic processes, this code employs synthetic varieties of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which nearly each element of the resultant buildings can be systematically managed. In this conceptual framework, the structural and purposeful advancements are described in order to outline the present amount of sophistication and to forecast upcoming Instructions on the platform.
crystal Alteration is variable: absent in lots of crystals, in Other individuals developing dense sericite aggregates which can show some recrystallization effects to make coarser-grained white mica. In the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes arranged in aggregates. From your Cambridge English Corpus Furthermore, haloarchaeal cells were embedded within salt crystals less than laboratory problems and more info subsequently analysed by light microscopy. Through the Cambridge English Corpus The white clouds (generally sparse) were being also commonly considered becoming made up of small crystals of h2o ice, alternatively like cirrus within our atmosphere. In the Cambridge English Corpus They are really located in evaporite salt lakes and may be trapped in salt crystals throughout evaporation. Within the Cambridge English Corpus Consequently, the cells (organelles and membranes) are destroyed mechanically by ice crystals, bringing about Loss of life by means of cell lysis. Through the Cambridge English Corpus The crystals were being Utilized in the 1st or second orders of reflection. With the Cambridge English Corpus Inside our 8xperiments, the crystals ended up cubes that has a foundation area of eight e mm. With the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : effect of temperature and force.
