The polymer spheres and carbon particles arrange themselves spontaneously into the correct crystal structure when encouraged by a little heat, so manufacturing opalescent film should be easy.

只要加入一点聚合体球体和碳颗粒就可以自然地安排成正确的晶体结构，因此生产光亮的薄膜就很容易了。

The Illinois researchers made their electrode by coating a surface with tiny polystyrene spheres just a few hundred nanometers across, packing the spheres together into a regular lattice structure.

There was plenty of noise inside the spheres on a recent tour, as workers welded steel, pounded bolts into place and sawed concrete inside the half-built structure.

在前不久的一次参观中，球屋里充斥着各种噪音，在这个正在建设中的建筑里，工人们在焊接钢筋，打入螺栓，切割混凝土。

It involves creating a lattice made out of tiny polystyrene spheres and then filling the space in and around the structure with metal.
