So, then we'll get to turn to a new kind of mechanics or quantum mechanics, which will in fact be able to describe what's happening on this very, very small size scale -- so on the atomic size scale on the order of nanometers or angstroms, very small particles.

然后我们要讲到一种,新的力学--量子力学,它可以解释,发生在很小尺度,大约是原子尺寸大小,也就是纳米或埃的量级。
