These lie flat during swimming, trapping an insulating layer of air and keeping the inner fur and skin dry.

游泳时这些针毛贴在身上将一层空气锁住，以保持里面的皮毛干燥。

The scientists covered batteries with a material—technically a quantum-tunneling composite—in which microparticles of conductive metal are suspended in an insulating layer.

科学家们用一种名为QTC合成物的材料裹住电池从而使得导电的金属微粒在绝缘层内同外界隔离。

As temperatures rise in a CLT building, the material's outer layer will char, insulating the inner layers for up to three hours.

在 CLT 建筑中，随着温度的升高，这种材料的外层会烧焦，从而产生对内层的隔热，长达三个小时之久。

Traditionally, we use really rough insulating layers to support copper wires.

传统上，我们使用非常粗糙的绝缘层来支撑铜线。

A thin insulating layer separates these conductive lines from others that are arranged as columns.

薄绝缘层将这些导线与其他排列成列的分开。

By recreating a grazing ecosystem, the idea is that animals foraging for food in the winter could trample down the insulating layer of snow.

通过重建一个放牧的生态系统，他们的想法是，在冬天觅食的动物可以踩下积雪的绝缘层。

Which might not seem that helpful now, but to our hairy ancestors, it was a way to trap air in our furry insulating layer.

虽然鸡皮疙瘩现在看起来没啥用，但对于我们浑身长毛的祖先来说，这样能把冷空气隔绝在我们毛发的隔热层里。

See, wetsuits are designed to let in some water and trap it with all those insulating layers.

看， 潜水服的设计目的是让一些水进入并用所有这些绝缘层将其锁住。

Many are fairly small, though the largest species can weigh up to 150 kilograms. Notothenioids can be identified by their large eyes, which are covered by a thick insulating layer of clear tissue.

许多体型相当小，但最大的物种可重达 150 公斤。 Notothenioids 可以通过它们的大眼睛来识别，它们被一层厚厚的透明组织绝缘层覆盖。
