结晶的形状非常细小,需要用显微镜才能看得清楚,外观上看起来是平滑、块状。常见最多的是各式玛瑙
The ordered interior composition of huge crystals, such as fluorite and quartz shown right here, is reflected of their geometric styles.
Crystalline construction is characterised by a geometric, repeating sample of symmetric molecular structure. The arrangement of atoms sorts these ordered, repeating designs.
Monoclinic �?Characterized by 3 unequal axes, two of which intersect at an oblique angle, while the 3rd is perpendicular towards the airplane of the opposite two.
Insert to phrase list Add to term listing [ C/U ] transparent rock that looks like ice, or simply a bit of it

There are actually other minerals and molecules which will sort these crystal lattices. Snowflakes are a classic illustration of a approximately symmetric and geometrically patterned construction from ice crystals, and gemstones of all types are typically crystals.
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。
