27Local economists have looked into their crystal balls and witnessed a thing somewhat nasty.当地的经济学者们已预测到将会出现棘手的问题。《柯林斯英汉双解大词典》
Bismuth (Bi) appears to get a metallic, but the quantity of electrons accessible for electrical conduction is similar to that of semiconductors. In actual fact, bismuth is termed a semimetal. Molecular solids are usually crystals fashioned from molecules or polymers. They can be insulating, semiconducting, or metallic, according to the sort of molecules from the crystal. New molecules are constantly remaining synthesized, and lots of are made into crystals. The quantity of unique crystals is big.
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。
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
Crystalline framework is characterized by a geometrical, repeating sample of symmetric molecular framework. The arrangement of atoms forms these ordered, repeating patterns.
无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。
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
The elements are uncovered in many different crystal packing preparations. The commonest lattice constructions for metals are People obtained by stacking the atomic spheres into essentially the most compact arrangement.
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 freshly crystallized quartz grains are characterised by elongate crystals oriented oblique to your shear band margins, defining an average grain-shape foliation. 来自 Cambridge English Corpus We say the chain topology in the large w area acts as the proverbial ' scratch-on-theglass ' wanted from the organic and natural chemistry laboratory to produce crystals. 来自 Cambridge English Corpus The age scatter among the the individual crystals could mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene forms neutral to pale brown, click here subhedral to anhedral crystals, from time to time containing inclusions of plagioclase microlaths and opaque phases.
Within the Cambridge English Corpus We say the chain topology while in the superior w location functions because the proverbial ' scratch-on-theglass ' necessary inside the natural chemistry laboratory to make crystals. Through the Cambridge English Corpus Regular-tension and temperature molecular-dynamics simulations of crystals in the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Within the Cambridge English Corpus Together with these, dust particles have already been noticed in lower-temperature plasmas, like Individuals used in plasma processing and plasma crystals. Through the Cambridge English Corpus The ultimate Element of the ebook focuses on peculiarities of strongly coupled dusty plasmas, such as the development of dust crystals and related eye-catching forces. In the Cambridge English Corpus Total characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Most important morphologies were not observed. From your Cambridge English Corpus See all samples of crystal These examples are from corpora and from resources on the internet. Any views during the illustrations do not signify the view with the Cambridge Dictionary editors or of Cambridge University Press or its licensors.
Orthorhombic: These are generally rhombic prisms and dipyramids that resemble tetragons but with no sq. cross-sections.
This Assessment chronicles above two decades of study into developing a genetic code for crystal engineering. In lieu of directing biological processes, this code makes use of artificial varieties of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about each individual element of the resultant structures can be systematically managed. Within this conceptual framework, the structural and functional advancements are described in an effort to outline the present amount of sophistication also to predict potential Instructions of your platform.
矿物成分：针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶，如发晶、钛晶、绿幽灵等，发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶；含铁�?；呈金黄色或柠檬�?)称黄水晶；含锰和钛呈玫瑰色者称蔷薇石英，即粉水晶；烟色者称烟水晶；褐色者称茶晶；黑色透明者称为墨晶。
