To activate the grip, the lizards extend and angle their setae to create millions of contact points with a surface.

为了紧抓住平面，蜥蜴伸展并且弯曲刚毛 以便产生和表面的数以百触点。

And each of the setae is covered in even tinier bristles called spatulae.

这些刚毛被更小的多叫做匙突(spatulae)的结构覆蓋。

One square millimeter of a gecko's footpad has 14,000 hair-like structures called setae.

壁虎脚趾上一平方毫米，有一四千个毛状结构叫刚毛。

They work in the same way as the setae on the feet of geckos. They produce the same Van Der Waals forces.

它们的原理与壁虎脚上的刚毛相同。它们会产生同样的范德华力。

And it is because the small setae are very close to the wall.

因为小刚毛离墙很。

These setae can bend to make contact with all the grooves and crevices in a surface.

刚毛可以弯曲与表面上的所有沟壑与裂缝进行连。

The large numbers of setae produce very strong forces. They give the geckos wonderful " sticking" power.

大量的刚毛会产生非常强大的力量。它们赋予壁虎奇妙的“粘着”力量。

To adhere, the setae rely on small electromagnetic attractions between molecules called van der Waals forces.

为了具有粘附性，刚毛依靠的是分子间被称为范德华力的力产生的微弱电磁吸引力。

The molecules in the setae and the wall pull towards each other, and form a link.

刚毛和细胞壁中的分子相互吸引，形成连。

Just like flies, Gecko, toe pads are covered with hundreds of tiny hairs called setae.

就像苍蝇一样，壁虎的足垫上覆盖着数百根微小的刚毛。

So this right here is one seta, or one segment within the worm.

所以这里是一个环节，或者说是蠕虫体内的一个节段。

Whenever Apollo takes a step, the setae flatten to make close contact with the surface.

每当阿波罗迈出一步，刚毛就会变平，与表面紧密触。

Hold on, Pinkie! Hang on with those setae hairs!

坚持住, Pinkie! 坚持住那些setae头!

Each toe of a gecko foot is packed with millions of tiny hair-like structures called setae.

壁虎脚的每个脚趾都有数以百的微小毛状结构，称为刚毛。
