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。
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。
10This is the silicon chip—just a little chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
The ordered interior composition of large crystals, such as the fluorite and quartz proven listed here, is reflected of their geometric shapes.
How Crystals Type The entire process of forming a crystal is called crystallization. Crystallization usually occurs any time a strong crystal grows from the liquid or Alternative.
无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。

11I diligently opened the package deal and located a crystal bell inside.我小心地打开包裹，发现里面有一个水晶钟。
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。

16I opened the box and observed a piece of crystal snowflake plus a greeting card with "Content Birthday" in the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
Crystals are not only renowned for their physical look, but distinct crystals of various elements and formations may lead to an unlimited assortment of uses and Actual physical Homes.
⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
crystal Alteration is variable: absent in many crystals, in Other folks manufacturing dense sericite aggregates which can exhibit some recrystallization outcomes to create coarser-grained white mica. From your Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally arranged in aggregates. In the Cambridge English Corpus Additionally, haloarchaeal cells were embedded within just salt crystals less than laboratory conditions and subsequently analysed by light-weight microscopy. Through the Cambridge English Corpus The white clouds (typically sparse) were being also commonly considered to be currently being made up of small crystals of h2o ice, relatively like cirrus inside our atmosphere. From the Cambridge English Corpus They're located in evaporite salt lakes and may be trapped in salt crystals during evaporation. Through the Cambridge English Corpus Hence, the cells (organelles and membranes) are ruined mechanically by ice crystals, resulting in Dying by way of mobile lysis. From your Cambridge English Corpus The crystals were being Employed in the initial or next orders of reflection. Within the Cambridge English Corpus In our 8xperiments, the crystals had been cubes by using a foundation website place of eight e mm. With the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and strain.
