17These rings are indicative of your crystal composition of nickel and will be discussed only by invoking wavelike properties of light.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
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。
10This could be the silicon chip—somewhat chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
You'll find many different crystals depending on geometric buildings, crystal progress, and content. There is often arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid buildings.
They can finally create a nice little uniform cluster of atoms, This is certainly the process of escalating crystals. The greater they might occur jointly, the greater of a formation will probably be noticeable towards the naked eye. Experts can decide what mineral These are checking out by how the crystals kind.
Increase to word record Add to term record [ C/U ] clear rock that appears like ice, or simply a bit of it
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
A crystal method refers to the classification of crystals depending on the geometric arrangement and symmetry in their lattice structures. You will find seven key crystal units:
Within the Cambridge English Corpus We are saying the chain topology from the significant w region acts because the proverbial ' scratch-on-theglass ' necessary within the organic chemistry laboratory to make crystals. From the Cambridge more info English Corpus Continuous-pressure and temperature molecular-dynamics simulations of crystals of the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From the Cambridge English Corpus In addition to these, dust particles are actually noticed in very low-temperature plasmas, like Individuals Employed in plasma processing and plasma crystals. Within the Cambridge English Corpus The final Section of the reserve concentrates on peculiarities of strongly coupled dusty plasmas, including the formation of dust crystals and involved eye-catching forces. In the Cambridge English Corpus Entire characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From your Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Key morphologies weren't noticed. Within the Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from sources on the internet. Any thoughts while in the examples do not symbolize the belief of your Cambridge Dictionary editors or of Cambridge University Push or its licensors.
You'll find only some diverse unit-mobile shapes, so many alternative crystals share just one unit-cell variety. An essential attribute of a unit cell is the quantity of atoms it consists of. The entire variety of atoms in all the crystal would be the selection in Every mobile multiplied by the quantity of unit cells. Copper and aluminum (Al) Every single have a person atom for each device mobile, though zinc (Zn) and sodium chloride have two. Most crystals have only some atoms for each unit mobile, but there are a few exceptions. Crystals of polymers, for instance, have A large number of atoms in Each individual device mobile.
crystal, any sound material wherein the component atoms are organized in the definite pattern and whose surface regularity reflects its internal symmetry.
⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
