17These rings are indicative of your crystal construction of nickel and might be stated only by invoking wavelike Houses 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。
①压电效�?在机械力(压力或拉�?作用下，水晶单晶体的两端会产生电荷，其电量相等但符号相反。在工业上，无色、无缺陷、不具双晶的水晶常被用来作压电石英片。
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。

无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。

Several crystals behave like butter in that they're tricky at small temperatures but comfortable at larger temperatures. They are called solids in the least temperatures beneath their melting stage. A attainable definition of a reliable is an object that retains its condition if left undisturbed. The pertinent issue is how much time the article keeps its condition. A highly viscous fluid retains its shape for an hour but not a year. A stable ought to keep its form longer than that.

You will discover only a few distinct unit-mobile shapes, so a variety of crystals share one unit-cell kind. An important characteristic of the device mobile is the amount of atoms it includes. The full variety of atoms in the entire crystal will be the selection in Just about every mobile multiplied by the volume of unit cells. Copper and aluminum (Al) click here Each individual have 1 atom per unit cell, whilst zinc (Zn) and sodium chloride have two. Most crystals have only some atoms per unit cell, but there are some exceptions. Crystals of polymers, for example, have thousands of atoms in Every single unit cell.
⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
