Crystal Secrets
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。12He tried once more in many other metropolitan areas and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
4Without a crystal ball, It is really unachievable to convey exactly where we'll be future year.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》
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
How Crystals Form The whole process of forming a crystal is named crystallization. Crystallization generally happens every time a reliable crystal grows from the liquid or Remedy.
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
30Three days went earlier, and I used to be shocked to check out it once more: each of the openings were being sewed up by skinny and white thread plus they looked much like the ice crystal on Wintertime's branches from the north.
To be a very hot Remedy cools or even a saturated solution evaporates, particles draw shut more than enough for chemical bonds to sort. Crystals also can type from deposition straight from the gas section. Liquid crystals possess particles oriented within an structured way, like stable crystals, nonetheless are able to stream.
Metallic Crystals: Metals usually type metallic crystals, where by a few of the valence electrons are no cost to move through the entire lattice. Iron, by way of example, can form different metallic crystals.
crystal The newly crystallized quartz grains are characterized by elongate crystals oriented oblique to your shear band margins, defining a normal grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology in the high w location acts because the proverbial ' scratch-on-theglass ' needed during the organic chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter amid the individual crystals may replicate incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene varieties neutral to pale brown, subhedral to anhedral crystals, from time to time made up of inclusions of plagioclase microlaths and opaque phases.
. The second layer is shaded within the determine. It has precisely the same plane-triangular construction; the atoms sit within the holes formed by the first layer. The primary layer has two equal sets of holes, but the atoms of the 2nd layer can occupy only one set. The third layer, labeled C
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体

crystal Alteration is variable: absent in several crystals, in Other individuals developing dense sericite aggregates which can show some recrystallization results to generate coarser-grained white mica. From your Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are sometimes arranged in aggregates. Within the Cambridge English Corpus Also, haloarchaeal more info cells were embedded in salt crystals below laboratory ailments and subsequently analysed by light microscopy. From the Cambridge English Corpus The white clouds (typically sparse) had been also greatly considered getting composed of little crystals of water ice, alternatively like cirrus in our ambiance. From your Cambridge English Corpus They may be found in evaporite salt lakes and might be trapped in salt crystals for the duration of evaporation. In the Cambridge English Corpus As a result, the cells (organelles and membranes) are ruined mechanically by ice crystals, leading to Demise via mobile lysis. From the Cambridge English Corpus The crystals had been Employed in the first or 2nd orders of reflection. In the Cambridge English Corpus In our 8xperiments, the crystals had been cubes which has a foundation area of eight e mm. Through the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and force.
