Not known Factual Statements About Crystal

8Where can we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球?

23Sometimes, however, the crystal kind of the silicate inclusions is observed to resemble extra closely the internal construction of diamond than that of other silicate minerals.然而,有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。

These innovations contain unique buildings with programmable lattice symmetries and perfectly-described crystal routines, responsive components that leverage the intrinsic Homes of nucleic acids to control buildings on desire, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that provide insights into light–subject interactions. Seeking ahead, we obstacle the Group to leverage the remarkable structural Handle afforded by crystal engineering with DNA to synthesize courses of purposeful materials that thrust past what has become doable with The natural way developing crystalline elements or These created by extra traditional procedures.

Fig. 7: A template-directed tactic can Handle The position of constructing blocks on the floor within the development of sophisticated structures.

看抛光:抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。

, has a similar structure, but There are 2 possibilities for choosing the holes the atoms will occupy. The third layer is often placed more than the atoms of the main layer, making an alternate layer sequence A

⑦、镀彩:运用类似电镀的手法在水晶表面以不同的色彩,层面较薄,经摩擦可划伤�?;出现划痕,由于镀彩经常位于底部,因此在镀彩底部经常采用其它对象附着,如生肖文镇。

Crystals is usually developed beneath average ailments from all ninety two Normally developing aspects besides helium, and helium is usually crystallized at minimal temperatures through the use of twenty five atmospheres of tension.

Quite a few crystals behave like butter in that they're tough at very low temperatures but soft at greater temperatures. They can be identified as solids in the slightest degree temperatures under their melting level. A probable definition of the good can be an object that retains its form if left undisturbed. The pertinent challenge is just how long the thing retains its shape. A really viscous fluid retains its form for one hour but not a yr. A reliable need to hold its condition more time than that.

[ C/U ] clear glass of top of the range, commonly with its surface area cut into designs that replicate gentle

From the Cambridge English Corpus We are saying the chain topology while in the significant w region acts as being the proverbial ' scratch-on-theglass ' necessary from the natural chemistry laboratory for making crystals. From your Cambridge English Corpus Consistent-strain and temperature molecular-dynamics simulations of crystals of the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. In the Cambridge English Corpus As well as these, dust particles have already been noticed in small-temperature plasmas, like Those people Utilized in plasma processing and plasma crystals. From your Cambridge English Corpus The final Component of the e-book concentrates on peculiarities of strongly coupled dusty plasmas, including the development of dust crystals and check here connected desirable forces. From the Cambridge English Corpus Finish 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 maybe more irregular, Major morphologies were not observed. With the Cambridge English Corpus See all samples of crystal These examples are from corpora and from sources on the web. Any viewpoints while in the examples usually do not stand for the belief of the Cambridge Dictionary editors or of Cambridge University Push or its licensors.

水晶的价值还与块体大小有关,同样的颜色和净度级别,块越大越难得。有时候质量级别虽然低一些,但块体够大,也可能价格高于高级别的小晶体

压电性:水晶晶体受到压力时会产生电荷;反之,受到电压作用时,晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能,称压电性。

⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
