27Local economists have appeared into their crystal balls and seen something fairly unpleasant.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》
①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
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。
Monoclinic �?Characterised by three unequal axes, two of which intersect at an oblique angle, even though the third is perpendicular to your plane of the other two.
水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。
1A crystal chandelier lit the place.一盏水晶吊灯照亮了房间。《柯林斯英汉双解大词典》
Lots of crystals behave like butter in that they're challenging at minimal temperatures but comfortable at bigger temperatures. They can be referred to as solids whatsoever temperatures beneath their melting point. A achievable definition of a stable is definitely an object that retains its form if still left undisturbed. The pertinent situation is just how long the article retains its shape. A extremely viscous fluid retains its form for an hour although not a 12 months. A sound will have to hold its form extended than that.
晶体 Silicon crystals developed within a laboratory transform light into electrical Electricity. 在实验室中长成的硅晶体可将光线转变为电能。
Through the Cambridge English Corpus We are saying the chain topology in the large w area acts as being the proverbial ' scratch-on-theglass ' wanted in the organic and natural chemistry laboratory to make crystals. From your Cambridge English Corpus Consistent-force and temperature molecular-dynamics simulations of crystals of your lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Within the Cambridge English Corpus Along with these, dust particles are actually noticed in reduced-temperature plasmas, like Individuals used in plasma processing and plasma crystals. Within the Cambridge English Corpus The ultimate Section of the e book focuses on peculiarities of strongly coupled dusty plasmas, including the formation of dust crystals and connected attractive forces. In the Cambridge English Corpus Full characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. Through the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or check here more irregular, Main morphologies weren't noticed. Within the Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from sources on the internet. Any views within the illustrations usually do not characterize the viewpoint of the Cambridge Dictionary editors or of Cambridge University Push or its licensors.
Molecular Crystals: Full molecules are bonded to one another in an organized fashion. A fantastic case in point can be a sugar crystal, which consists of sucrose molecules.
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
The C60 molecules, also known as buckyballs, are quite robust and Virtually incompressible. Crystals are shaped these kinds of that the balls are organized within an fcc lattice using a one particular-nanometre spacing in between the centres of adjacent balls. The identical C70 molecule has The form of a rugby ball; C70 molecules also kind an fcc crystal when stacked collectively. The strong fullerenes kind molecular crystals, with weak binding—provided by van der Waals interactions—involving the molecules.
