This is saying, just look, whatever you have here, just iterate through it n times.

这就是说，看看，无论你在这里有什么，只要迭代 n 次。

We have computer optimization techniques so we can design a far more efficient aerodynamic shape, versus having to iterate slowly through wind tunnels.

我们有计算机优化技术，这样我们就可以设计出更有效的空气动力学外形，而不是在风洞中缓慢迭代。
