This team began with commercially available rebars made from carbon-fibre composite.

这个团队开始使用由碳纤维复合材料制成的商业。

And so then you picked up the rebar?

所以你就捡起了？

You didn't happen to keep the rebar, did you?

你没有留着那根吧？

The classic example is the steel mini mills which first produced low-quality rebar, then moved to sheet steel, stealing business from the large mills that had been dominant.

典型的例子是小型铁厂，它们先是生产低质量的螺纹，然后转向生产板，从一直占主导地位的大型铁厂那里抢走了生意。

We unpacked our donkeys with difficulty -- the ropes were stiff as rebar -- and pounded our tent stakes into iron-cold earth.

He has a piece of rebar sticking out his chest.

他的胸腔里插了根。

But because water gets in through tiny cracks, the rebars rust. This causes them to expand, widening the cracks and weakening the concrete.

但是因为水会从细小的裂缝里渗透进来，所以会生锈了。这会导致裂缝扩大，混凝土变软。

Reinforcing concrete with steel rods called rebars is the basis of modern construction.

混凝土是现代建筑的基础。

Dr. Reid will extract the rebar.

Reid医生现在要把这个来。

Commerce Department has decided the cheap rebar from Mexico and Turkey unfairly harm US producers.

商务部已裁定来自墨西哥和土耳其的廉价螺纹不公平地损害了美国生产商。

Tangled rebar was thrown nearly a mile away.

So you have people who are digging by hand with sharpened pieces of rebar and they are tunneling into the rock formations to try to find dinosaur teeth and bone and other kinds of animals remains as well.

所以有人用手拿着磨尖的片在岩石中挖掘隧道，试图找到恐龙的牙齿和骨头，以及其他动物的遗骸。

Replacing rebar doesn't just mean less material;it can make sites safer, offer more flexibility and save time, which is just what's needed on a project that's been more than a little controversial.

更换不仅意味着更少的材料； 它还可以使工地更安全，提供更大的灵活性并节省时间， 这正是一个颇具争议的项目所需要的。

But I think it's really interesting to compare the exterior walls of the survival condo are up to nine feet thick of epoxy hardened concrete with roughly 600 tons of rebar.

但我认为，将生存公寓的外墙——厚度可达九英尺的环氧树脂硬化混凝土，并配有约600吨的——与SILO的外墙进行比较，确实非常有趣。

You know, so I have this visual in my mind of her, you know, walking on rebar, you know, on the balls of her feet in these four inch heels.

But the problem with reinforced concrete, especially if the rebar isn't covered with enough concrete and is exposed to water and salt, is that the steel inside can rust.

但混凝土的问题在于，特别是如果没有被足够的混凝土覆盖并且暴露在水和盐中，里面的会生锈。

The team have worked out how to minimize cost by using carbon fiber rebars only where strictly necessary In other places they use glass fiber which is cheaper.

团队已经研究如何通过仅在严格必要的情况下使用碳纤维来降低成本，在其他地方他们使用更便宜的玻璃纤维。

And so if you start recycling the existing property, that puts a lot more rebar into steel and you've produced a lot of the steel already.

因此， 如果你开始回收现有资产，这将大大增的回收利用， 并且你已经生产了大量的材。
