A sound is crystalline if it's extensive-vary buy. After the positions of an atom and its neighbours are regarded at a person place, the place of every atom is understood specifically all through the crystal. Most liquids deficiency very long-assortment buy, While several have short-variety order. Quick range is outlined as the very first- or next-nearest neighbours of the atom. In several liquids the very first-neighbour atoms are arranged in the identical structure as from the corresponding solid section.
the stable point out of many basic substances, that have an everyday condition and surfaces organized in identical designs
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。

根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
They'll ultimately produce a nice very little uniform cluster of atoms, This is often the whole process of increasing crystals. The more they are able to arrive collectively, the more of the formation will be noticeable into the bare eye. Scientists can establish what mineral These are looking at by how the crystals variety.
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。

Metallic Crystals: Metals generally variety metallic crystals, exactly where many of the valence electrons are free to maneuver through the lattice. Iron, by way of example, can read more type unique metallic crystals.
crystal The newly crystallized quartz grains are characterized by elongate crystals oriented oblique for the shear band margins, defining an average grain-shape foliation. 来自 Cambridge English Corpus We say the chain topology while in the significant w area acts because the proverbial ' scratch-on-theglass ' required within the natural chemistry laboratory to help make crystals. 来自 Cambridge English Corpus The age scatter between the person crystals might reflect incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene varieties neutral to pale brown, subhedral to anhedral crystals, at times that contains inclusions of plagioclase microlaths and opaque phases.
. The 2nd layer is shaded in the determine. It has the same aircraft-triangular composition; the atoms sit during the holes fashioned by the main layer. The very first layer has two equal sets of holes, but the atoms of the second layer can occupy only one established. The third layer, labeled C
隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
crystal, any reliable product in which the element atoms are organized in a definite pattern and whose area regularity displays its interior symmetry.
