27Local economists have appeared into their crystal balls and witnessed anything fairly awful.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》

These innovations include things like exotic constructions with programmable lattice symmetries and well-outlined crystal routines, responsive materials that leverage the intrinsic properties of nucleic acids to govern structures on demand, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals offering insights into gentle–make any difference interactions. Hunting ahead, we challenge the Local community to leverage the extraordinary structural Management afforded by crystal engineering with DNA to synthesize classes of purposeful supplies that press past what has been feasible with By natural means transpiring crystalline products or People made by extra typical tactics.
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。
How Crystals Variety The whole process of forming a crystal is referred to as crystallization. Crystallization generally takes place every time a sound crystal grows from the liquid or Answer.
当二氧化硅结晶完美时就是水晶；结晶不完美的就是石英：二氧化硅胶化脱水后就是玛瑙；二氧化硅含水的胶体凝固后就成为蛋白石；二氧化硅晶粒小于几微米时，就组成玉髓、燧石、次生石英岩。
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。
11I thoroughly opened the package and located a crystal bell within.我小心地打开包裹，发现里面有一个水晶钟。
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。
A crystal method refers back to the classification of crystals based on the geometric arrangement and symmetry of their lattice constructions. You will discover seven main crystal methods:
say cheese a thing that somebody that is using a photograph of you informs you to mention so that the mouth can make The form of the smile
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
The framework of your sodium atoms alone, or the chlorine atoms on your own, is fcc and defines the unit Crystal mobile. The sodium chloride framework Hence is produced up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) relies about the bcc construction; each individual other atom is cesium or chlorine. In such cases, the device cell is often a cube. The third significant construction for AB
crystal Alteration is variable: absent in lots of crystals, in Many others making dense sericite aggregates which may present some recrystallization results to create coarser-grained white mica. Within the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are occasionally organized in aggregates. Through the Cambridge English Corpus Also, haloarchaeal cells were being embedded in just salt crystals underneath laboratory conditions and subsequently analysed by mild microscopy. Through the Cambridge English Corpus The white clouds (generally sparse) were also widely considered becoming made up of little crystals of water ice, somewhat like cirrus in our ambiance. In the Cambridge English Corpus They may be present in evaporite salt lakes and might be trapped in salt crystals for the duration of evaporation. With the Cambridge English Corpus For that reason, the cells (organelles and membranes) are destroyed mechanically by ice crystals, bringing about death by way of mobile lysis. In the Cambridge English Corpus The crystals have been Utilized in the very first or 2nd orders of reflection. With the Cambridge English Corpus In our 8xperiments, the crystals have been cubes with a foundation space of eight e mm. From your Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : result of temperature and stress.
