A reliable is crystalline if it has very long-assortment get. When the positions of the atom and its neighbours are recognised at a person position, the spot of every atom is understood specifically throughout the crystal. Most liquids absence extended-vary buy, Whilst many have limited-array buy. Quick variety is described as the primary- or next-closest neighbours of the atom. In lots of liquids the initial-neighbour atoms are organized in a similar structure as from the corresponding strong section.
12He tried using again in numerous other towns and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
Most reliable materials located in character exist in polycrystalline type rather than as one crystal. They are actually composed of an incredible number of grains (modest crystals) packed jointly to fill all space. Every single person grain has another orientation than its neighbours. Despite the fact that long-assortment order exists within a person grain, for the boundary among grains, the purchasing changes route. A normal bit of iron or copper (Cu) is polycrystalline.
25If you're a Billy Crystal supporter, you can expect to appreciate this movie.如果你是比利·克里斯特尔的影迷，你就会喜欢这部电影。《柯林斯英汉双解大词典》
Monoclinic �?Characterised by three unequal axes, two of which intersect at an oblique angle, while the third is perpendicular to your airplane of the opposite two.
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
Ionic Crystals: Electrostatic forces form ionic bonds. A basic instance is often a halite or salt crystal.
Metallic Crystals: Metals usually kind metallic crystals, where a lot of the valence electrons are cost-free to move through the lattice. Iron, such as, can variety various metallic crystals.
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。
. The next layer is shaded within the determine. It's the identical aircraft-triangular framework; the atoms sit from the holes shaped by the initial layer. The 1st layer has two equal sets of holes, but the atoms of the next layer can occupy just one set. The 3rd layer, labeled C
Fig. 1: Schematic of crystal formation from creating blocks made up of a particle Main in addition to a shell of DNA ligands connected to the particle surface.
This Evaluation chronicles in excess of two check here decades of exploration into developing a genetic code for crystal engineering. In lieu of directing Organic procedures, this code utilizes synthetic types of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which nearly every single element of the resultant buildings can be systematically controlled. Within this conceptual framework, the structural and useful innovations are described in an effort to outline the existing level of sophistication also to forecast long run Instructions on the System.
Tetragonal �?Characterized by three mutually perpendicular axes, two of which can be equal in size, although the third is for a longer time or shorter and perpendicular to the other two.
