诗中“胜美玉”，“过冰清”，写出水晶的质地美，而“亦欲应时明”则描绘出水晶充满灵性的动态美，耐人寻味。罗维是有独特眼光，懂得水晶真谛，第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实；以水晶为直接吟咏对象的诗篇还有：

23Sometimes, nevertheless, the crystal form of the silicate inclusions is noticed to resemble more carefully The inner 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。

景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。

Large crystals of diamond are valuable gemstones. The crystal has other appealing Homes; it's got the highest audio velocity of any sound and is the best conductor of heat. Moreover diamond, one other typical type of carbon is graphite, which happens to be a layered materials. Just about every carbon atom has a few coplanar near neighbours, forming an arrangement called the honeycomb lattice. Three-dimensional graphite crystals are received by stacking equivalent layers.

2She was putting on a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》

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

11I diligently opened the deal and found 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。

Solids that have short-array order but lack extended-assortment purchase are named amorphous. Practically any substance can be built amorphous by speedy solidification through the soften (molten state). This issue is unstable, and the strong will crystallize in time. When the timescale for crystallization is a long time, then the amorphous point out appears stable.

. The second layer is shaded while in the figure. It's a similar aircraft-triangular framework; the atoms sit in the holes fashioned by the primary layer. The initial layer has two equal sets of holes, although the atoms of the next layer can occupy only one established. The third layer, labeled C

Fig. one: Schematic of crystal formation from creating blocks composed of a particle Main as well as a shell of DNA ligands connected into the particle area.

This Evaluate chronicles above twenty years of investigation into creating a genetic code for crystal engineering. In lieu of directing biological procedures, this code utilizes synthetic varieties of DNA to programme check here the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which almost just about every aspect of the resultant structures might be systematically managed. In just this conceptual framework, the structural and functional advances are described in order to determine the current amount of sophistication and also to forecast long run Instructions in the platform.
