This concept applies equally in a single, two, and 3-dimensional Areas. The whole crystal lattice could be manufactured by frequently reproducing the pattern from the device mobile in all directions.
A fundamental idea in crystal constructions would be the device cell. It's the smallest device of volume which allows identical cells to get arranged alongside one another to occupy all offered Place. The geometrical foundation of all crystals could be the lattice. A lattice is often considered as an everyday and infinite arrangement of points or atoms, where Every position or atom has An analogous bordering atmosphere.
10This is the silicon chip—somewhat chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
If you would like see how crystals are fashioned, you may perform a little undertaking with your very personal kitchen area and find out the formation with the crystals take place along with your possess eyes . This may be finished by putting a small quantity of table salt into some typical tap water, wait around 24 several hours, and you will see great cubed formations. This comes about as the water is evaporating, which brings about the atoms which make up the salt (the mineral) and the drinking water to return closer collectively.
Crystalline framework is characterized by a geometrical, repeating pattern of symmetric molecular construction. The arrangement of atoms kinds these requested, repeating patterns.
Encyclopaedia Britannica's editors oversee subject places in which they have intensive information, whether or not from a long time of experience obtained by engaged on that content material or by way of examine for a sophisticated diploma. They generate new information and validate and edit written content acquired from contributors.
水晶内部有多种矿物包裹体,形成的各种景观可以肉眼观测,这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石,因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性,具有极高欣赏和收藏价值。
市场上有很多人把熔炼水晶也叫做合成水晶,那是不准确的,一般都是以水晶废料为原料在高温高压下熔炼出来的,而不是结晶成的,不具备水晶的晶体特性,所以不能把熔炼水晶与合成水晶混为一谈;但是熔炼水晶耐高温,用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等,实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
Crystals tend to be seen as one thing of immense attractiveness, and they are generally made use of with diamonds or other stones for making items of jewelry. The majority of crystals now are male-manufactured in laboratories.
crystal The newly crystallized quartz grains are characterised by elongate crystals oriented oblique for the shear band margins, defining an average grain-condition foliation. 来自 Cambridge English Corpus We are saying the chain topology within the superior w location acts because the proverbial ' scratch-on-theglass ' necessary within the natural and organic chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age scatter among the the person crystals may well replicate incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, often made up of inclusions of plagioclase microlaths and opaque phases.
From your Cambridge English Corpus We are saying the chain topology from the higher w location acts as being the proverbial ' scratch-on-theglass ' wanted in the natural and organic chemistry laboratory to create crystals. In the Cambridge English Corpus Continual-force and temperature molecular-dynamics simulations of crystals in the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From the Cambridge English Corpus In addition to these, dust particles happen to be noticed in minimal-temperature plasmas, like All those used in plasma processing and plasma crystals. With the Cambridge English Corpus The final part of the reserve concentrates on peculiarities of strongly coupled dusty plasmas, such as the formation of dust crystals and associated beautiful forces. With the Cambridge English Corpus Total characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, primary morphologies were not noticed. In the Cambridge English Corpus See all examples of crystal These examples are from corpora and from sources online. Any opinions while in the illustrations don't depict the impression of your Cambridge Dictionary editors or of Cambridge University Press or its licensors.
You can find only some different device-cell styles, so many alternative crystals share a single unit-mobile style. A crucial attribute of a unit mobile is the number of atoms click here it contains. The full quantity of atoms in the entire crystal is the variety in each cell multiplied by the quantity of unit cells. Copper and aluminum (Al) each have 1 atom per device mobile, while zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms per unit cell, but there are some exceptions. Crystals of polymers, by way of example, have A huge number of atoms in each device cell.
⑦双色水晶:一种紫色和黄色共存一体的水晶,紫色、黄色之间界限较明显,分别占据晶块的一部分。
