这意味着要用高能的电子或光子束来处理食品，用它们来干扰微生物的DNA，阻止微生物释放危险的毒素和增殖。

That means treating food with high-energy bursts of electrons or photons to attack the micro-organisms' DNA, preventing them from spitting out dangerous toxins and proliferating.

And one thing that Einstein put forth is he figured if well, what we're saying is that light is, in fact, a stream of particles, each one of those particles or photons must, therefore, have a momentum.

爱因斯坦提出了一件事情,他指出如果我们所说的光，事实上是一束粒子，那么这些粒子或者光子中的，每一个都有动量。
