天然的水晶一般都会有絮状(绵绺),也就是大家俗称的瑕疵,这是液体水落石出和二氧化碳的小孔穴,而人工合成的水晶就不会有这样的特征。
12He tried using yet again in various other cities 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。
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。
Fig. 3: A library of lattice symmetries may be accessed by shifting the particle core and DNA shell.
You can also find numerous resources that resemble crystals but are literally polycrystals. Polycrystals sort when microscopic crystals fuse with each other to form a strong. These resources will not encompass ordered lattices.
Lattices can have a person lattice stage for each mobile or more than one, yielding a total of 14 Bravais crystal lattice sorts. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the 3-dimensional array produced by a set of discrete factors.
石英:《广雅》称水晶叫石英,色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释:�?�?,白石英�?”。
②固体包裹体:指呈固态相存在包裹体,多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
仿制钛晶树水晶:钛晶是水晶里价格最昂贵的,造假者当然也不会放过这么好的产品。天然的环境下,在水晶里能生长个像树一样的钛晶,完全是可能的,只是这样的货很少,那我们的造假专家是如何做的呢,白水晶底下打个洞,激光打点成板状的钛晶进去,就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面,会采用将钛晶部位割成板状,与圆面的水晶粘合的方法来制作。
crystal The newly crystallized quartz grains are characterized by elongate crystals oriented oblique for the shear band margins, defining a standard grain-form foliation. 来自 Cambridge English Corpus We say the chain topology in the significant w region functions given that the proverbial ' scratch-on-theglass ' wanted from the organic chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age scatter amongst the individual crystals might mirror incorporation of xenocrysts from before magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene kinds neutral to pale brown, subhedral to anhedral crystals, sometimes that contains inclusions of plagioclase microlaths and opaque phases.
15The trick to a great thermoelectric substance is usually a crystal framework by which electrons can flow freely.制造一种好的热电材料的关键是,需要一种电子可以自由流动的晶体结构。
国家还并未给天然水晶提供一个等级划分的具体标准,水晶品种繁杂,每一品种都有他不同的评判标准。
《古今小说·李公子救蛇获称心》:“器皿皆是玻璃、水晶、琥珀、玛瑙为之,曲尽巧妙,非人间所有。”
Binary crystals are present in lots of buildings. Some pairs of elements variety multiple framework. At space temperature, get more info cadmium sulfide might crystallize both inside the zinc blende or wurtzite structure. Alumina also has two possible constructions at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals show unique buildings at diverse temperatures. Among the many most intricate crystals are Individuals of silicon dioxide (SiO2), which has seven unique structures at various temperatures and pressures; the most typical of such structures is quartz.
