17These rings are indicative of the crystal structure of nickel and will be discussed only by invoking wavelike Attributes of sunshine.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。

Crystals are gorgeous rock formations which have shocked human beings for thousands of decades. They're utilized for many different things, not just for decoration. Many of the 1st radios ever invented utilized crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Distinctive Qualities and harmonic capabilities of crystals to generate very accurate measurements and adjustments.

A crystal construction focuses on how the atoms are arranged inside the crystal. Nonetheless, crystallographers are interested in the general shape and dimensions in the crystal together with its exterior attributes. To perform this, they have to find out about the crystal process.

看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。

You'll find numerous crystals based on geometric constructions, crystal expansion, and materials. There may be arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid structures.

Not all crystals variety in water, but nearly all crystals sort the same way, atoms come alongside one another and turn into a uniformed cluster. The process may take as very little as a couple of days to maybe a thousand a long time. Organic crystals that originate from the Earth form the identical way.

水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。

Q.four. What is the distinction between atomic structure and crystal construction? Ans. The key difference between atomic composition and crystal framework lies of their definitions: atomic structure refers to how atoms are arranged in a single molecule or possibly a cluster of molecules, Whilst crystal framework problems the precise arrangement of atoms in just a solid material.

[ C/U ] clear glass of top of the range, ordinarily with its floor Reduce into designs that mirror gentle

From the Cambridge English Corpus We say the chain topology during the significant w area acts because the proverbial ' scratch-on-theglass ' necessary during the organic and natural chemistry laboratory to help make crystals. Within the Cambridge English Corpus Continual-strain and temperature molecular-dynamics simulations of crystals in the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. With the Cambridge English Corpus In combination with these, dust particles have been observed more info in reduced-temperature plasmas, like those Employed in plasma processing and plasma crystals. With the Cambridge English Corpus The final part of the ebook concentrates on peculiarities of strongly coupled dusty plasmas, including the formation of dust crystals and associated beautiful forces. In the Cambridge English Corpus Comprehensive characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From your Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, Principal morphologies were not noticed. Through the Cambridge English Corpus See all samples of crystal These examples are from corpora and from sources on the net. Any opinions within the illustrations never represent the feeling of the Cambridge Dictionary editors or of Cambridge College Push or its licensors.

The arrangement of an atom’s electrons determines its chemical Qualities. The Attributes of solids are usually predictable with the Attributes in their constituent atoms and molecules, and the different shell buildings of atoms are hence accountable for the diversity of solids.

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。

对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
