27Local economists have seemed into their crystal balls and witnessed something fairly horrible.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》
③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。
A fundamental idea in crystal structures could be the device mobile. It's the smallest device of volume that permits equivalent cells to become stacked alongside one another to fill all House. By repeating the pattern of your device cell time and again in all directions, your entire crystal lattice might be manufactured. A cube is the simplest illustration of a unit mobile. Two other examples are proven in Figure one. The primary could be the unit mobile for a deal with-centred cubic lattice, and the second is to get a physique-centred cubic lattice. These structures are discussed in the subsequent 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。
. These four structures comprise the majority of the binary crystals with equal numbers of cations and anions.
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
Crystals glance special from many other rocks and minerals, but �?barring several Exclusive circumstances �?almost all minerals cover a crystalline structure underneath the area.
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。

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。
The framework with the sodium atoms by yourself, or the chlorine atoms alone, is fcc and defines the device cell. The sodium chloride composition thus is made up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is predicated to the bcc structure; each individual other atom is cesium or chlorine. In such cases, the unit mobile can be a dice. The third significant structure for AB
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。
