Mount Tambora, a large stratovolcano erupted with a VEI measurement of 7.

一座巨大的层状火，坦博拉火爆发了，VEI等级为7级。

The layers and tight weave make it harder for virus-carrying particles to pass through the material.

这种层状结构和紧密的编织使得携带病毒的颗粒很难穿透这种材料。

Interestingly, while the bases of stratiform clouds  are generally flat, they tend to develop significant features at the top due to wind and  temperature changes.

有趣的是， 虽然层状云的底部通常是平坦的，但由于风和温度的变化， 会在顶部形成显的特征。

The surface of the glacier was further characterized by dirt bands and the outcropping edges of the blue veins, showing the laminated structure of the ice.

冰川表面的进一步特征是污垢带和蓝色纹理的露头边缘，显示出冰的层状结构。

So there are many other terrestrial laminated deposits from around the world, and those terrestrial deposits are, they can be subdivided into lake deposits, meandering river deposits, and then just the general flats.

所以世界各地还有很多其他的陆地层状沉积物，而这些陆地沉积物，可以细分为湖泊沉积物、蜿蜒的河流沉积物，然后就是一般的平地沉积物。

Now, Asperitas clouds are  thought to be mostly a supplementary feature of stratiform clouds, which are low elevation  layered clouds without vertical development, although asperitas have also been observed to  be stratocumulus or altocumulus.

现在， 阿斯佩里塔云被认为主要是层状云的补充特征，层状云是低海拔层状云， 没有垂直发展，尽管阿斯佩里塔也被观察到是层积云或高积云。

While stratiform clouds  often have what is known as Kelvin-Helmholtz instability at the top, an instability that  comes from a velocity shear within fluids, this instability is more unusual at the base of clouds.

虽然层状云的顶部通常存在所谓的开尔文-亥姆霍兹不稳定性，这种不稳定性来自于流体内的速度剪切，但这种不稳定性在云的底部更为不寻常。

To the schists succeeded gneiss, partially stratified, remarkable for the parallelism and regularity of its lamina, then mica schists, laid in large plates or flakes, revealing their lamellated structure by the sparkle of the white shining mica.

片岩之后是片麻岩，部分分层，因其片层的平行性和规则性而引人注目，然后是云母片岩，铺成大片或片状，通过白色闪亮云母的闪光揭示了的层状结构。
