看颜色:即使在同一种类的水晶中,它的不同部位的纹理、色泽也各式各有千秋。属于单色的,要色度均匀;在同一块水晶上有深浅的,则要求其色调纹路美观大方。
Crystals are beautiful rock formations that have stunned individuals for 1000s of years. They can be employed for quite a few different things, not only for decoration. Many of the first radios at any time invented made use of crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use special Houses and harmonic capabilities of crystals for making remarkably accurate measurements and adjustments.
A simple thought in crystal constructions is definitely the unit mobile. It's the smallest unit of volume that allows equivalent cells being stacked with each other to fill all space. By repeating the sample with the device mobile time and again in all directions, the entire crystal lattice can be created. A dice is The best example of a device mobile. Two other examples are revealed in Determine one. The first would be the device mobile to get a face-centred cubic lattice, and the 2nd is for your body-centred cubic lattice. These buildings are explained in the following paragraphs.
Fig. 3: A library of lattice symmetries is often accessed by switching the particle core and DNA shell.

Lattices might have a single lattice stage per cell or multiple, yielding a total of 14 Bravais crystal lattice sorts. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the three-dimensional array made by a set of discrete points.
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位,而对水晶来说,颜色和净度(水晶行业称作晶体)是近乎同等重要的因素:
11I thoroughly opened the package deal and found a crystal bell inside.我小心地打开包裹,发现里面有一个水晶钟。
Meanwhile, to ensure ongoing guidance, we're exhibiting the site without having models and JavaScript.
crystal The recently crystallized quartz grains are characterized by elongate crystals oriented oblique towards the shear band margins, defining a typical grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology during the high w location acts as the proverbial ' scratch-on-theglass ' wanted while in the organic chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter among the the person crystals could mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, at times made up of inclusions of plagioclase microlaths and opaque phases.
Within the Cambridge English Corpus We are saying the chain topology during the superior w area acts since the proverbial ' scratch-on-theglass ' necessary within the organic chemistry laboratory for making crystals. Within the Cambridge English Corpus Consistent-pressure and temperature molecular-dynamics simulations of crystals in the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. In the Cambridge English Corpus As well as these, dust particles are already noticed in reduced-temperature plasmas, like These used in plasma processing and plasma crystals. Within the Cambridge English Corpus The final Component of the e book focuses on peculiarities of strongly coupled dusty plasmas, including the development of dust crystals and associated beautiful forces. From the Cambridge English Corpus Finish characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. With the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or more irregular, Key morphologies weren't observed. In the Cambridge English Corpus See all samples of crystal These examples are from corpora and from sources online. Any opinions while in the illustrations don't depict the feeling of the Cambridge Dictionary editors or of Cambridge University Press or its licensors.
Crystals are not just renowned for their Actual physical physical appearance, but various crystals of various elements and formations can lead to a vast variety of utilizes and Bodily Homes.
14For instance, click here We've got Quartz crystal clocks and watches precise to inside 1 minute a year.例如,我们使用的每年误差不超过1分钟的石英水晶钟表和手表。
