Clinton says Washington is opening new business development centers and is working on a virtual entrepreneur network to link small-scale enterprises on line.

So, it's Newtonian mechanics, and the reason for this is because Newtonian mechanics does not work on this very, very small size scale.

牛顿力学，因为牛顿力学,在这种很小的尺度下不适用,我们说过，牛顿力学。

So, we need a new kind of mechanics, which is quantum mechanics, which will accurately explain the behavior of molecules on this small scale.

所以我们需要一种新的力学，也就是量子力学,来解释在这个,小尺度下分子的行为。

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。
