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。
A different enjoyable, and delicious, experiment is always to type significant crystals using sugar. By heating sugar with water and after that permitting this Resolution evaporate on sticks, you'll be able to kind rock candy from sugar crystals!
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
Increase to phrase record Add to term listing C2 [ U ] clear glass of quite superior quality, typically with its area Reduce into sensitive styles
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
They'll at some point create a nice very little uniform cluster of atoms, This really is the process of escalating crystals. The more they might occur alongside one another, the more of a formation will be obvious into the bare eye. Scientists can determine what mineral They are really thinking about by how the crystals sort.
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
Crystals are nothing at all a lot more than an requested arrangement of molecules or atoms. Crystals can be found in numerous shapes and sizes, and each has diverse characteristics. What they are created of establishes how it is going to type.

颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
You'll find only some diverse unit-cell styles, so numerous crystals share only one unit-cell style. A crucial characteristic of a unit mobile is the number of atoms it incorporates. The total amount of atoms in the whole crystal may be the variety in each mobile multiplied by the volume of device cells. Copper and aluminum (Al) Each individual have 1 atom for each unit cell, whilst zinc (Zn) and sodium chloride have two. Most crystals have just a few atoms for each device cell, but there are a few exceptions. Crystals of polymers, by way of example, have thousands of atoms in Every single unit mobile.
This Critique chronicles around 20 years of research into making a genetic code for crystal engineering. Instead of directing Organic processes, this code takes advantage of synthetic kinds of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which nearly every facet of click here the resultant buildings could be systematically managed. Inside this conceptual framework, the structural and useful developments are described in order to define the current volume of sophistication and to predict upcoming directions in the System.
crystal Alteration is variable: absent in lots of crystals, in Other people creating dense sericite aggregates which can display some recrystallization outcomes to create coarser-grained white mica. With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes arranged in aggregates. In the Cambridge English Corpus Also, haloarchaeal cells ended up embedded in salt crystals under laboratory disorders and subsequently analysed by gentle microscopy. From the Cambridge English Corpus The white clouds (normally sparse) were also broadly regarded as getting composed of very small crystals of drinking water ice, rather like cirrus within our ambiance. In the Cambridge English Corpus These are found in evaporite salt lakes and may be trapped in salt crystals during evaporation. Through the Cambridge English Corpus Therefore, the cells (organelles and membranes) are destroyed mechanically by ice crystals, resulting in Dying via mobile lysis. Within the Cambridge English Corpus The crystals were being used in the primary or next orders of reflection. Within the Cambridge English Corpus In our 8xperiments, the crystals have been cubes that has a foundation region of 8 e mm. From the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and strain.
