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 以便产生表以百万计接触点。

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

这些刚被更小多叫做匙突(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，有一万四千个发状结构叫刚。

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

因为小刚离墙很近。

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

刚胞壁中分子相互吸引，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.

刚可以弯曲与表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.

大量刚会产生非常强大力量。它们赋予壁虎奇妙“粘着”力量。

Each toe is covered with millions of tiny hair-like strands, called setae.

每个趾都覆盖着百万根小发状丝， 称为刚。

每当阿波罗迈出一步，刚就会变平，与表紧密接触。

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

壁虎每个趾都有以百万计微小发状结构，称为刚。

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相同。它们会产生同样范德华力。
