天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
12He tried using again in quite a few other metropolitan areas 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。
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
If you'd like to see how crystals are fashioned, it is possible to perform a little project within your very very own kitchen and see the development on the crystals take place with all your have eyes . This may be finished by putting a small volume of table salt into some frequent faucet h2o, hold out 24 hours, and you may see awesome cubed formations. This comes about since the h2o is evaporating, which results in the atoms that make up the salt (the mineral) along with the water to come back nearer together.
Crystalline framework is characterized by a geometric, repeating sample of symmetric molecular composition. The arrangement of atoms kinds these purchased, repeating patterns.
Monoclinic �?Characterised by 3 unequal axes, two of which intersect at an oblique angle, whilst the third is perpendicular into the aircraft of the other two.

22Working from what The usa previously is aware of about by itself, the bureau's gurus together with other demographers present an irresistible, if clouded, crystal ball amongst their visions.
The fundamental models of solids are either atoms or atoms that have put together into molecules. The electrons of an atom go in orbits that sort a shell composition throughout the nucleus. The shells are filled in a systematic buy, with each shell accommodating only a little number of electrons. Distinct atoms have distinctive numbers of electrons, that happen to be distributed within a characteristic Digital framework of stuffed and partially crammed shells.
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
水精：水晶为何称为水精，《广雅》有巧解：�?水之精灵�?”；李时珍则说：�?莹洁晶光，如水之精英 ”。细加考究，此称还蕴含浓厚的宗教意味呢。水精一名，最初见于佛书，后汉支曜翻译的《具光明定意经》说：�?其所行道，色如水�?�?。
crystal Alteration is variable: absent in several crystals, in Many others creating dense sericite aggregates which may show some recrystallization consequences to supply coarser-grained white mica. Through the Cambridge English Corpus The tridymite crystals here are rectangular or wedge-shaped and are sometimes arranged in aggregates. With the Cambridge English Corpus Moreover, haloarchaeal cells had been embedded in salt crystals below laboratory conditions and subsequently analysed by light microscopy. Through the Cambridge English Corpus The white clouds (normally sparse) were also commonly considered to be staying composed of very small crystals of water ice, instead like cirrus inside our atmosphere. Through the Cambridge English Corpus They can be located in evaporite salt lakes and can be trapped in salt crystals throughout evaporation. From the Cambridge English Corpus Thus, the cells (organelles and membranes) are ruined mechanically by ice crystals, bringing about death by mobile lysis. From the Cambridge English Corpus The crystals were being Employed in the main or 2nd orders of reflection. Within the Cambridge English Corpus Inside our 8xperiments, the crystals were cubes using a foundation area of eight e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and tension.
