27Local economists have appeared into their crystal balls and found something instead 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》

23Sometimes, nevertheless, the crystal sort of the silicate inclusions is observed to resemble a lot more intently the internal structure 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。

A basic idea in crystal structures is the device cell. It is the smallest device of volume that permits equivalent cells to be stacked together to fill all space. By repeating the pattern with the unit mobile again and again in all Instructions, the entire crystal lattice may be built. A cube is the simplest example of a device mobile. Two other illustrations are demonstrated in Figure 1. The primary could be the unit mobile to get a face-centred cubic lattice, and the second is for a system-centred cubic lattice. These buildings are defined in the following paragraphs.

养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。

Crystalline composition is characterized by a geometrical, repeating pattern of symmetric molecular structure. The arrangement of atoms forms these purchased, repeating patterns.

⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。

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

Crystals are very little more than an purchased arrangement of molecules or atoms. Crystals are available in many different shapes and sizes, and each one has distinct traits. Whatever they are created of determines how it can form.

水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：

The definition of the stable appears clear; a solid is mostly considered staying difficult and business. Upon inspection, having said that, the definition gets to be less simple. A cube of butter, for example, is tough following staying saved inside of a refrigerator which is clearly a strong. Soon after remaining about the kitchen counter for on a daily basis, the identical cube gets to be pretty tender, and it is actually unclear If your butter should still be thought of a good.

Through the Cambridge English Corpus We say the chain topology from the superior w location acts since the proverbial ' scratch-on-theglass ' required within the organic and natural chemistry laboratory to produce crystals. Through the Cambridge English Corpus Consistent-strain and temperature molecular-dynamics simulations of crystals with the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Within the Cambridge English Corpus Besides these, dust particles have already been observed in reduced-temperature plasmas, like those Utilized in plasma processing and plasma crystals. In the Cambridge English Corpus The final Component of the e-book concentrates on peculiarities of strongly coupled dusty plasmas, including the formation of dust crystals and related eye-catching forces. From the Cambridge English Corpus Comprehensive characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. In the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Most important morphologies weren't click here observed. With the Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from sources on the internet. Any thoughts during the illustrations do not signify the opinion of your Cambridge Dictionary editors or of Cambridge College Push or its licensors.

Crystal Lattices There are 7 systems of crystal buildings, which happen to be also referred to as lattices or space lattices:

玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
