But in the quantum world, a particle can still go through such an energy barrier without sufficient energy.

但是在量子世界中，一个粒子在没有足够能量的情况下仍然可以通过这样的能量屏障。

In quantum mechanics, a tiny object can zip right through an energy barrier that it would otherwise have to surmount in order for a chemical reaction to take place.

在量子力学中，为了使化学反应发生，微小物体能快速通过能量位垒而不用必须克服它。
