The cars will have a top speed of just 25mph and a front end made of soft foam to cushion unwary pedestrians.

无人驾驶汽车最高车速仅为25英每小时，其前端由软泡沫材制造而成，可缓冲粗心行人。

These plastics could be used for many kinds of cloth, as well as things such as 3D printed materials and foams.

这些塑可以用于多种布和其他材中，比如3D打印材和泡沫。

Three of the microscopic grains are locked in a foam material called aerogel, from the outside covering of Stardust.

其中三个微粒被封闭在一个从盖着“星尘”号宇宙飞船，名为“气凝胶”泡沫材。

It's actually the spray foam insulation I talked about, polyurethane foam.

实际上就是我提到喷涂泡沫保温材，聚氨酯泡沫。

I don't know, foamy stuff and silicon render.

我不知道，泡沫材和硅质涂。

Now, the hottest foam on the market right now is Polyether Block Amide or PEBAX, but this uses thermoplastic  polyurethane, which is a little bit stiffer, a little bit heavier, but a whole lot cheaper.

目前市场上最热门泡沫材是聚醚嵌段酰胺或PEBAX，但它使用是热塑性聚氨酯，这种材稍微硬一些， 重一些，但便宜得多。

But China, he says, has so-called industrial clusters, with everything you need for shoes, from raw materials to foam manufacturers, knitwear, lacing and embroidery groups.

他表示，中国拥有所谓产业集群，从原材到泡沫制造商、针织品、系带和刺绣集团，鞋类所需一切应有尽有。

Well, this foam that Nike came out with is so good that it actually returns way more energy than the average foam did.

耐克推出这种泡沫材非常出色，它实际上能比普通泡沫回馈更多能量。

Like what, if you could do this kind of big leap with a little innovation of foam, is there other stuff that you can do or further innovation of materials that make up the foam?

比如， 如果你能通过泡沫小创新实现这种大跃进，那么是否还有其他可以做事情， 或者对构成泡沫材进行更深层次创新呢？

So you can only have so much of that energy returning foam.

因此，你只能使用有限量那种能回弹泡沫材。

And essentially, what happened is, this probably dated back actually before 2015, Uh, you know, Nike decided, well, their, their, their, their, uh, development team, uh, was ahead of the curve.

实际上，这一情况可能追溯到2015年之前。那时，耐克公司决定，他们研发团队已经走在了行业前沿。他们研发出了一种新型泡沫材，类似于锐步泡沫技术。
