8Where can 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?
An additional fun, and tasty, experiment will be to variety large crystals working with sugar. By heating sugar with water and then allowing this Remedy evaporate on sticks, you could kind rock candy from sugar crystals!
4Without a crystal ball, It truly is difficult to say the place we will be up coming calendar 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》
If you need to see how crystals are formed, you may do a little project with your incredibly possess kitchen area and find out the development on the crystals occur using your own eyes . This can be completed by putting a little level of desk salt into some regular tap h2o, hold out 24 several hours, and you'll see great cubed formations. This takes place because the h2o is evaporating, which leads to the atoms that make up the salt (the mineral) and the water to return closer together.
Fig. four: Constructing blocks with distinctive styles and surface chemistries direct the formation of unique crystal symmetries.
Lattices can have just one lattice position for every mobile or multiple, yielding a total of 14 Bravais crystal lattice types. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the three-dimensional array made by a set of discrete factors.
解理:无解理。所谓解理是指矿物被打击时,沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类:极完全解理、完全解理、中等解理、不完全解理和无解理,水晶属于无解理。

多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
Within the Cambridge English Corpus We say the chain topology inside the significant w region acts given that the proverbial ' scratch-on-theglass ' wanted while in the natural chemistry laboratory to help make crystals. Within the Cambridge English Corpus Regular-tension and temperature molecular-dynamics simulations of crystals in the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Through the Cambridge English Corpus Along with these, dust particles have already been noticed in very low-temperature plasmas, like These Employed in plasma processing and plasma crystals. Through the Cambridge English Corpus The ultimate A part of the reserve concentrates on peculiarities of strongly coupled dusty plasmas, like the development of dust crystals and related beautiful forces. From the Cambridge English Corpus Finish characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From your Cambridge English more info Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, Most important morphologies were not noticed. From your Cambridge English Corpus See all samples of crystal These examples are from corpora and from resources on the web. Any thoughts while in the illustrations never stand for the viewpoint of your Cambridge Dictionary editors or of Cambridge College Press or its licensors.
Fig. one: Schematic of crystal formation from developing blocks made up of a particle Main and a shell of DNA ligands attached towards the particle area.
The composition in the sodium atoms by itself, or even the chlorine atoms by itself, is fcc and defines the unit cell. The sodium chloride construction Therefore is created up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is based within the bcc composition; every single other atom is cesium or chlorine. In cases like this, the device cell is actually a dice. The 3rd essential composition for AB
