水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。
One more fun, and delicious, experiment should be to type significant crystals applying sugar. By heating sugar with h2o and afterwards letting this Option evaporate on sticks, you'll be able to form rock sweet from sugar crystals!
结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙
Add to phrase listing Incorporate to term checklist C2 [ U ] clear glass of quite high quality, normally with its surface area cut into fragile styles
25If you're a Billy Crystal enthusiast, you can enjoy this movie.如果你是比利·克里斯特尔的影迷，你就会喜欢这部电影。《柯林斯英汉双解大词典》
当二氧化硅结晶完美时就是水晶；结晶不完美的就是石英：二氧化硅胶化脱水后就是玛瑙；二氧化硅含水的胶体凝固后就成为蛋白石；二氧化硅晶粒小于几微米时，就组成玉髓、燧石、次生石英岩。
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。
11I meticulously opened the offer and located a crystal bell inside of.我小心地打开包裹，发现里面有一个水晶钟。
Among the many binary crystals, the simplest structures to visualise are Individuals with equivalent figures of The 2 forms of atoms. The construction of sodium chloride is based with a dice. To assemble the lattice, the sodium and chlorine atoms are placed on alternate corners of the dice, as well as the composition is recurring (Determine 3B).
A crystal program refers back to the classification of crystals determined by the geometric arrangement and symmetry of their lattice buildings. There are seven main crystal systems:
16I opened the box and noticed a bit of crystal snowflake as well as a greeting card with "Happy Birthday" while in 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。
Crystallography may be the examine of crystals, and it deals with almost everything from best geometric shapes to seemingly random conglomerations of particles and minerals.
《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
crystal Alteration is variable: absent in many crystals, in Other folks producing dense sericite aggregates which may display some recrystallization consequences to produce coarser-grained white mica. In the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally arranged in aggregates. With the Cambridge English Corpus On top of that, haloarchaeal cells ended up embedded inside of salt crystals less than laboratory disorders and subsequently analysed click here by mild microscopy. With the Cambridge English Corpus The white clouds (ordinarily sparse) were being also widely thought to be currently being composed of very small crystals of h2o ice, rather like cirrus inside our atmosphere. With the Cambridge English Corpus They may be located in evaporite salt lakes and may be trapped in salt crystals throughout evaporation. From the Cambridge English Corpus Thus, the cells (organelles and membranes) are wrecked mechanically by ice crystals, bringing about Loss of life as a result of cell lysis. From your Cambridge English Corpus The crystals were being used in the very first or second orders of reflection. From your Cambridge English Corpus Within our 8xperiments, the crystals ended up cubes that has a base location of 8 e mm. With the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : result of temperature and force.
