8Where will we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球?
12He tried out all over again in numerous other cities 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。
10This may be the silicon chip—somewhat chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Most solid resources present in mother nature exist in polycrystalline kind as opposed to as one crystal. They are literally composed of a lot of grains (smaller crystals) packed together to fill all Room. Each and every individual grain has a distinct orientation than its neighbours. Whilst prolonged-range purchase exists inside of a person grain, in the boundary involving grains, the buying adjustments course. A standard piece of iron or copper (Cu) is polycrystalline.
水胆水晶,包括气态,液态,固态,有时候可以同时多态并存,无色居多,个别情况下可见红色,绿色,黄色,蓝色,黑色等。
Lattices could possibly have 1 lattice position for every mobile or multiple, yielding a complete of 14 Bravais crystal lattice forms. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array created by a list of discrete factors.
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。
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。
第三种是“皮景”,因某些其他的矿物与水晶体共生,或由于其他的物质侵蚀而依附于水晶表面,或者是水晶受自然环境的影响,在水晶表面出现蚀象,形成了一些景象或图案,这种景观存在于水晶表面。
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
There are 2 these kinds of achievable periodic arrangements. In Every single, the main layer has the atoms packed right into a airplane-triangular lattice in which each and every atom has six quick neighbours. Figure two demonstrates this arrangement for that atoms labeled A
Crystallography is the review of crystals, and it promotions with every thing from great geometric shapes to seemingly random conglomerations of particles and minerals.
⑨、喷砂:立体感弱,较平整,无凹凸感,机器雕刻文字、图形等后进行效果处理。成本低制作快。
crystal Alteration is variable: absent in several crystals, in Other people generating dense sericite aggregates which can exhibit some recrystallization effects to produce coarser-grained white mica. With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes arranged in aggregates. In the Cambridge English Corpus Additionally, haloarchaeal cells had been embedded within salt crystals beneath laboratory problems and subsequently analysed by website mild microscopy. From the Cambridge English Corpus The white clouds (usually sparse) were being also broadly viewed as getting composed of very small crystals of water ice, somewhat like cirrus in our environment. From the Cambridge English Corpus They are really found in evaporite salt lakes and might be trapped in salt crystals during evaporation. From your Cambridge English Corpus For that reason, the cells (organelles and membranes) are ruined mechanically by ice crystals, bringing about Loss of life as a result of cell lysis. Through the Cambridge English Corpus The crystals ended up used in the primary or 2nd orders of reflection. Through the Cambridge English Corpus Inside our 8xperiments, the crystals were being cubes which has a foundation space of eight e mm. With the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and tension.
