Metals are generally defined by the physical traits we associate with them they're hard but malleable, meaning they can be hammered into thin sheets, but they're also ductile or can be pulled into wires.

我们一般根据相关联物理性质定义金属，它们都很硬，但有可塑性，这意味着它们能被锤成薄片。但它们也有延展性，可以被拉成电线。

Not only we need a 3D model, but you need the physics, built into those models to see how this fabric flows, like it's going to stretch -- CRANE: Stretches, right.

我们不仅需要3D模型，还需要实际手感，我们需要让这些模型展现出这种布料手感，比如说延展性——科林：对，延展性。

And I've designed and created the most realistic, expandable extendable lightsaber.

我设计并制作出了最逼、有延展性可伸缩光剑。

Bones, while hard, are not malleable, meaning they do not bend, so they break easily.

骨，又硬又没有延展性，这代表它们无法弯曲，因此它们易碎。

But being soft and malleable is far from impotent.

但是柔软和有延展性远不是无能。

It can also be used for something that's attached with elastic or something stretchy. You can pull it, and it will snap back into place.

这个词也可以用来描述那种有弹性和延展性东西。你可以把它拉长，它会自己弹回去。

It's a malleable, some sort of fried corn perhaps?

它有延展性，也许是某种油炸玉米？

Once carefully rinsed and washed, it became a material of extraordinary malleability and durability.

经反复淘洗，它就会成为一种有非凡延展性和耐久性材料。

It focused on changing the fit of its women's jeans with more flexible fabrics.

它专注于用更延展性面料提升女式牛仔裤舒适度。

So in short, the brain is malleable.

简而言之，大脑有良好延展性。

It can also be easily drawn out into wire, and for this reason we call it ductile.

通过拉伸，人们就可以获得铜线，因此我们说铜有延展性。

First, the soft flexible substance inside the bone channels isn't necessarily the remains of blood vessels.

首先，骨管内柔软而有延展性物质不一定就是血管化石。

Ductile means that something is able to deform without losing its strength.

延展性意味着某物能够变形而不会失去其强度。

And also it's what makes them malleable.

这也是它们有延展性原因。

In spite of their orderly arrangement though, most metals are quite malleable.

尽管它们排列很有规律，大多数金属仍然相当有延展性。

It's certainly more malleable than the ones [laughs] I was making.

它肯定比我做那些更延展性（笑）。

I like this because it's white but it dries clear and it's malleable.

我喜欢这个，因为它是白色，但它干得很干净而且有延展性。

So the solution is to make the steel softer, more malleable.

因此，解决办法是使钢材变得更软、更延展性。

And what ductility means is that it's ductile.

而延展性意味着它是可延展。

Human lungs have essentially the same setup, but in healthy people, alveoli stay properly inflated because they're full of chemicals called pulmonary surfactants that make the small alveoli more stretchy and less squeezy, balancing the pressure between air sacs.

人类肺基本上结构相同， 但在健康人中，肺泡能够保持适当膨胀， 因为它们充满了称为肺表面活性物质化学物质， 这些物质使小肺泡更延展性且不易被压缩， 从而平衡了气囊之间压力。
