As it builds up, so the calcite forms decorations that hang from the ceiling, stalactites.

" The inside looks like a crystal cave because the limestone has leaked calcite into little stalactites, " says Lin, who entered the tomb and used lidar (light detection and ranging) to explore it on the show.

“里面看起来就像一个水晶洞，因为灰岩中的方解已经漏成了小钟乳，”他进入墓室，并在节目中使用激光雷达（光探测和测距）进行了探索。

Made of calcite rods, the same stuff that forms limestone, they constituted the earliest visual systems known.

The example you're looking at right now is calcite, and when you're seeing double, it's because light with one polarization is getting bent at a different rate than light with the other polarization.

你现在看到的例子是方解，当你看到重影时， 是因为一种偏振的光以不同的速率被弯曲， 而另一种偏振的光则不是。

Between the size of a grain of rice and a small lima bean, a recent discoveries have found calcite and magnetite crystals chips in it or fragments.

大小介于一粒米和一颗小利马豆之间，最近的发现表明其中含有方解和磁铁矿晶体碎片。

Calcite is the more stable of the two and less prone to dissolving over time, so most mollusk shells have a sturdy outer layer of calcite.

方解是两者中更稳定的一种，随着时间的推移不易溶解，因此大多数软体动物的壳都有一层坚固的方解外层。

Plus, they were covered from their rounded heads to their many segmented feet in an exoskeleton made of calcite and chitin.

Little things like these formations, these rock formations, calcium carbon and calcite, that seem to defy gravity.

些像是岩层、碳酸钙和方解形成的构造，看起来好像在违背地心引力。

He dimly recalls the subtle variations in texture, the distinctive calcite deposits that run up the length of the wall, stretching up, up, to a small window in the rock.

他模糊地记得那些细微的质地变化，沿着墙面延伸的特有的方解沉积物，一直向上伸展， 直到岩上的一小扇窗户。
