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。
the sound point out of many basic substances, that have a daily shape and surfaces organized in comparable patterns
人造水晶分为熔炼水晶与养殖晶:据水晶专家汪毅的阐述,随着水晶的价值提高,喜欢的人增多,水晶也引起了作伪者的兴趣,现阶段中国水晶市场常见的造假方法为:
Increase to phrase record Add to phrase checklist C2 [ U ] clear glass of really high-quality, ordinarily with its floor Slice into delicate styles
2She was donning a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》
⑧、雕刻:立体感强,工艺高,做工精细,成本高。分手工雕刻图形、机器雕刻文字。
Crystals seem exceptional from a number of other rocks and minerals, but �?barring a couple of Exclusive conditions �?almost all minerals hide a crystalline structure underneath the area.

Among the many binary crystals, the simplest buildings to visualise are those with equal figures of the two varieties of atoms. The construction of sodium chloride is based on the cube. read more To build the lattice, the sodium and chlorine atoms are put on alternate corners of a cube, and also the construction is repeated (Figure 3B).
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。
地质学家目前为止对晶洞形成还没有广泛认同的理论,但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴,甚至动物挖的地洞。经过漫长时间,空腔的外壁变硬,溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间,缓慢渗入的矿物使得晶体在空腔内部结晶。
You'll find other minerals and molecules that could type these crystal lattices. Snowflakes really are a common illustration of a approximately symmetric and geometrically patterned structure from ice crystals, and gemstones of all types are typically crystals.
This Assessment chronicles over two decades of investigate into creating a genetic code for crystal engineering. In lieu of directing Organic procedures, this code takes advantage of artificial types of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about every aspect of the resultant structures is usually systematically controlled. Inside this conceptual framework, the structural and practical improvements are explained in order to outline the current amount of sophistication and to forecast potential directions of your platform.
