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，蜥蜴伸展并且弯曲刚毛 以便产生数以百万计接触点。

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

这些刚毛被更小多叫做匙突(spatulae)结构覆蓋。

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

壁虎趾上一平方毫米，有一万四千个毛发状结构叫刚毛。

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

因为小刚毛离墙很近。

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

刚毛壁中分子相互吸引，形成连接。

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

为了具有粘附性，刚毛依靠是分子间被称为范德华力力产生微弱电磁吸引力。

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

刚毛可以弯曲与上所有沟壑与裂缝进行连接。

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

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

壁虎每个趾都有数以百万计微小毛发状结构，称为刚毛。

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

它们原理与壁虎上刚毛相同。它们会产生同样范德华力。
