17These rings are indicative with the crystal construction of nickel and will be stated only by invoking wavelike Homes of sunshine.这些光圈表明了了镍的晶体结构,而且只能通过光线中波的特征来解释。

⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体,这些包裹体的存在,影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质,与水晶整体不协调,被视为水晶的杂质,有这种杂质的水晶是次品。

These improvements involve exotic structures with programmable lattice symmetries and well-outlined crystal behaviors, responsive materials that leverage the intrinsic Attributes of nucleic acids to manipulate structures on demand, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals that offer insights into mild–issue interactions. Wanting forward, we problem the Group to leverage the extraordinary structural control afforded by crystal engineering with DNA to synthesize courses of useful resources that drive over and above what continues to be probable with Obviously taking place crystalline supplies or People created by much more conventional approaches.

Encyclopaedia Britannica's editors oversee issue locations during which they've in depth expertise, no matter if from many years of expertise obtained by working on that articles or by means of review for an advanced degree. They write new material and verify and edit articles received from contributors.

这种水晶观赏石特指水晶晶簇,它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。

These examples are from corpora and from resources online. Any opinions in the examples never depict the view on the Cambridge Dictionary editors or of Cambridge University Push or its licensors.

Crystals search one of a kind from many other rocks and minerals, but �?barring several Exclusive conditions �?nearly all minerals hide a crystalline structure beneath the area.

You will find there's comparable directive about crystal glass which differentiates amongst full direct crystal, direct crystal and crystal.

Amongst the binary crystals, the simplest structures to visualize are All those with equivalent quantities of the two different types of atoms. The construction of sodium chloride is based on a cube. To assemble the lattice, the sodium and chlorine atoms are put on alternate corners of a dice, and the construction Crystal is repeated (Figure 3B).

幽灵水晶,分绿幽灵,红幽灵,白幽灵等,主要组成为绿泥石,其中绿幽灵属于珍贵品种。

15The trick to a fantastic thermoelectric substance is a crystal structure through which electrons can stream freely.制造一种好的热电材料的关键是,需要一种电子可以自由流动的晶体结构。

Fig. 1: Schematic of crystal formation from making blocks made up of a particle Main in addition to a shell of DNA ligands connected for the particle surface area.

水精:水晶为何称为水精,《广雅》有巧解:�?水之精灵�?”;李时珍则说:�?莹洁晶光,如水之精英 ”。细加考究,此称还蕴含浓厚的宗教意味呢。水精一名,最初见于佛书,后汉支曜翻译的《具光明定意经》说:�?其所行道,色如水�?�?。

Fig. 5: The chance to understand defined crystal behavior is dependent on the symmetry engineering tactic.
