A stable is crystalline if it has long-variety buy. Once the positions of an atom and its neighbours are identified at one position, the put of each and every atom is thought exactly through the entire crystal. Most liquids deficiency lengthy-assortment buy, Though quite a few have shorter-array get. Limited assortment is defined as the initial- or next-closest neighbours of the atom. In lots of liquids the primary-neighbour atoms are arranged in precisely the same framework as from the corresponding reliable stage.
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
These developments incorporate unique constructions with programmable lattice symmetries and effectively-outlined crystal routines, responsive products that leverage the intrinsic Qualities of nucleic acids to control buildings on desire, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that offer insights into gentle–matter interactions. Hunting ahead, we challenge the Local community to leverage the amazing structural Management afforded by crystal engineering with DNA to synthesize courses of useful resources that thrust beyond what continues to be attainable with Obviously transpiring crystalline resources or Individuals made by a lot more standard strategies.
We've written about about 300 stones inside the mineral kingdom! Read about Every stone's exclusive origin, history, and energies underneath.
Crystalline structure is characterised by a geometric, repeating sample of symmetric molecular construction. The arrangement of atoms types these ordered, repeating patterns.
Monoclinic �?Characterized by a few unequal axes, two of which intersect at an oblique angle, even though the third is perpendicular into the airplane of the opposite two.
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
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。
Crystals are frequently viewed as something of huge splendor, plus they are generally utilised with diamonds or other stones to produce pieces of jewellery. The majority of crystals now are man-built in laboratories.
say cheese something which someone that is having a photograph of you informs you to mention so that the mouth makes The form of the smile
Through the Cambridge English Corpus We say the chain topology within the large w region functions because the proverbial ' scratch-on-theglass ' wanted within the organic and natural chemistry laboratory to create crystals. From the Cambridge English Corpus Regular-tension and temperature molecular-dynamics simulations of crystals in the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From the Cambridge English Corpus Besides these, dust particles are observed in lower-temperature plasmas, like People Employed in plasma processing and plasma crystals. With the Cambridge English Corpus The ultimate Component of the ebook concentrates on peculiarities of strongly coupled dusty plasmas, like the development of dust crystals and related interesting forces. Through the Cambridge English Corpus Entire characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. Within the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or more irregular, Key morphologies weren't noticed. In the Cambridge English Corpus See all examples of crystal These examples are from corpora and from sources on the net. Any viewpoints inside the examples tend not to characterize the view on the Cambridge Dictionary editors or of Cambridge University Push or its licensors.
Orthorhombic: They are rhombic prisms and dipyramids that resemble tetragons but with out square cross-sections.
crystal, any reliable materials through which the element atoms are organized in a very definite sample and whose surface area regularity reflects its inner symmetry.
21You all know how any time you take a crystal prism and move more info a beam of daylight by it, you receive a spectrum, which seems like a ongoing band of rainbow hues.
