其它描述:《庶物异名疏》中说: �?水精出大秦国,一名黎�?�?。结晶完整的水晶晶体,就如参差交错的马齿,所以人们又叫它马牙石。先民们最早用它研磨成眼镜片,因而送它一个眼镜石的绰号。水晶有通称,也有俗称。广州一带称水晶叫晶玉,又名鱼脑冻;江苏东海县山民发现水晶会 �?窜火�?�?,于是给它起个放光石的俗名。世间一物多名,不足为奇,而像水晶拥有这么多的别称,实不多见。瞧,从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等,简直构成一部奇石鉴赏史。
Bismuth (Bi) seems being a metal, but the number of electrons accessible for electrical conduction is comparable to that of semiconductors. Actually, bismuth known as a semimetal. Molecular solids tend to be crystals formed from molecules or polymers. They may be insulating, semiconducting, or metallic, depending on the variety of molecules inside the crystal. New molecules are continuously remaining synthesized, and a lot of are made into crystals. The volume of diverse crystals is enormous.
A crystal composition concentrates on how the atoms are arranged In the crystal. Having said that, crystallographers are interested in the general form and measurement from the crystal together with its exterior attributes. To perform this, they have to know about the crystal process.
诗中道出一段唐代由盛变衰的史实。玄宗末年,杨贵妃得宠,三姐妹并封为国夫人。他们养尊处优,奢华至极,仆人用水晶盘将珍馐佳肴端到宴席上,美人觉得没有口味,懒得动筷子。作为“诗圣”作为“史诗”,紫驼一段写饮食之精美,不空发议论,只尽情揭露事实,无一刺讥语,无一慨叹声,却使人于以外得之:此诗之善讽也。以史为鉴,这样的世道,这样的人物,国家不出“安史之乱”那样的大祸反倒不正常了。
Crystalline construction is characterized by a geometrical, repeating sample of symmetric molecular structure. The arrangement of atoms types these requested, read more repeating designs.
第二种是“半包裹体”,在水晶结晶以后,由于受到地球引力的影响而产生的裂隙,晶体外的一些物质通过水晶的裂隙渗透到水晶内部,一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹,常被称为“通道”,这种包裹体所形成的景象相对地较受自然环境和时间的影响,相应的价值也比较�?。
30Three days went past, and I had been shocked to check out it again: many of the openings ended up sewed up by slim and white thread plus they looked just like the ice crystal on Winter season's branches in the north.
The weather are discovered in a variety of crystal packing arrangements. The most common lattice structures for metals are those received by stacking the atomic spheres into essentially the most compact arrangement.
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:
say cheese something that somebody that is getting a photograph of you tells you to say so that your mouth helps make the shape of the smile
The basic models of solids are possibly atoms or atoms that have mixed into molecules. The electrons of the atom move in orbits that kind a shell framework around the nucleus. The shells are loaded in a systematic order, with each shell accommodating only a little variety of electrons. Different atoms have distinctive quantities of electrons, that are dispersed in the attribute electronic composition of filled and partly crammed shells.
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。
crystal, any reliable materials during which the ingredient atoms are organized within a definite sample and whose floor regularity displays its inside symmetry.
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。
