27Local economists have appeared into their crystal balls and observed some thing somewhat nasty.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》
A elementary plan in crystal buildings will be the device mobile. It is the smallest unit of volume that allows identical cells being arranged jointly to occupy all out there Room. The geometrical foundation of all crystals could be the lattice. A lattice could be seen as a regular and infinite arrangement of points or atoms, the place Each individual stage or atom has an identical bordering atmosphere.
A crystal construction concentrates on how the atoms are organized In the crystal. Even so, crystallographers are interested in the general condition and measurement with the crystal as well as its exterior features. To accomplish this, they have to learn about the crystal technique.
Most stable elements found in mother nature exist in polycrystalline kind in lieu of as only one crystal. They are actually made up of countless grains (compact crystals) packed with each other to fill all space. Each particular person grain has another orientation than its neighbours. While prolonged-variety buy exists inside 1 grain, with the boundary concerning grains, the purchasing alterations way. A standard bit of iron or copper (Cu) is polycrystalline.
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
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。
水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。
You will find there's very similar directive about crystal glass which differentiates between full guide crystal, lead crystal and crystal.
Crystals tend to be seen as a little something of huge beauty, and so they are generally made use of with diamonds or other stones to help make pieces of jewelry. Nearly all crystals now are male-designed in laboratories.
[ C/U ] clear glass of top quality, usually with its surface area Slash into designs that reflect light-weight
From your Cambridge English Corpus We say the chain topology while in the substantial w region acts as the proverbial ' scratch-on-theglass ' necessary within the here natural and organic chemistry laboratory to produce crystals. From the Cambridge English Corpus Continual-force and temperature molecular-dynamics simulations of crystals of your lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Within the Cambridge English Corpus In addition to these, dust particles are actually observed in very low-temperature plasmas, like Individuals Employed in plasma processing and plasma crystals. From the Cambridge English Corpus The final part of the ebook concentrates on peculiarities of strongly coupled dusty plasmas, like the development of dust crystals and affiliated desirable forces. In the Cambridge English Corpus Comprehensive characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. In the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Most important morphologies were not noticed. Through the Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from resources online. Any viewpoints during the examples usually do not stand for the opinion from the Cambridge Dictionary editors or of Cambridge University Push or its licensors.
Fig. one: Schematic of crystal development from creating blocks composed of a particle Main and also a shell of DNA ligands connected for the particle surface.
The framework in the sodium atoms on your own, or even the chlorine atoms on your own, is fcc and defines the device mobile. The sodium chloride construction As a result is created up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) relies within the bcc construction; every other atom is cesium or chlorine. In such cases, the unit mobile can be a cube. The 3rd vital framework for AB
21You all understand how after you take a crystal prism and move a beam of sunlight through it, you can get a spectrum, which appears like a constant band of rainbow colours.
