17These rings are indicative of the crystal framework of nickel and may be stated only by invoking wavelike Qualities of light.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。
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:
Most reliable resources found in mother nature exist in polycrystalline kind in lieu of as only one crystal. They are actually made up of an incredible number of grains (small crystals) packed with each other to fill all Room. Each individual unique grain has a special orientation than its neighbours. While extensive-selection order exists in just a person grain, with the boundary involving grains, the ordering changes path. A normal bit of iron or copper (Cu) is polycrystalline.

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�?。

You will discover other minerals and molecules which can kind these crystal lattices. Snowflakes certainly are a common example of a around symmetric and geometrically patterned construction from ice crystals, and gemstones of all kinds are typically crystals.
Crystals are categorised generally classes, for instance insulators, metals, semiconductors, and molecular solids. Only one crystal of an insulator is often clear and resembles a bit of glass. Metals are shiny Until they've rusted. Semiconductors are sometimes shiny and sometimes clear but are never rusty. Many crystals might be labeled as one style of reliable, while others have intermediate conduct. Cadmium sulfide (CdS) is often ready in pure kind and is a wonderful insulator; when impurities are additional to cadmium sulfide, it becomes an interesting semiconductor.
