This concept applies equally in a single, two, and 3-dimensional spaces. Your entire crystal lattice can be made by repeatedly reproducing the sample with the device cell in all directions.
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
A crystal construction focuses on how the atoms are arranged Within the crystal. Nevertheless, crystallographers have an interest in the overall shape and dimensions of the crystal along with its external qualities. To perform this, they have to understand about the crystal system.
Increase to term list Increase to term list C2 [ U ] clear glass of pretty high-quality, generally with its surface area Lower into fragile patterns
C2 [ U ] clear glass of quite premium quality, typically with its floor Lower into sensitive styles:
Not all crystals form in water, but nearly all crystals variety exactly the same way, atoms appear jointly and turn into a uniformed cluster. The procedure may take as minimal as a few days to perhaps a thousand yrs. Pure crystals that originate from the Earth kind the same way.
30Three days went past, and I used to be stunned to find out it all over again: all of the openings were being sewed up by skinny and white thread plus they seemed much like the ice crystal on winter's branches in the north.
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
Metallic Crystals: Metals frequently variety metallic crystals, in which many of the valence electrons are free of charge to move all over the lattice. Iron, such as, can sort distinct metallic crystals.

In the Cambridge English Corpus We say the chain topology inside the significant w location acts as the proverbial ' scratch-on-theglass ' required from the organic and natural chemistry laboratory to help make crystals. Within the Cambridge English Corpus Regular-force and temperature molecular-dynamics simulations of crystals in the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. In 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. Through the Cambridge English Corpus The final Element of the guide focuses on peculiarities of strongly coupled dusty plasmas, including the development of dust crystals and linked interesting forces. In the Cambridge English Corpus Comprehensive characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. Through the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, primary morphologies were not noticed. From your Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from resources on the web. more info Any opinions while in the illustrations will not represent the feeling of your Cambridge Dictionary editors or of Cambridge College Push or its licensors.
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
