切伦科夫光来自光速被超过时的这些粒子。
Cherenkov light comes from these particles when the speed of light is exceeded.
这些乏燃料释放出的粒子，它们的速度要快于光速在水中的速度，因此会产生一种名为切伦科夫(契伦科夫)射线的本身无害光线。
The particles the fuel gives off, which travel faster than the speed of light in water, can as a result produce a particular type of light, harmless in itself, called Cerenkov radiation.
切伦科夫辐射是用粒子物理学的“标准模型”所预测到的，在现实世界中也观察到了，最经常是从核反应堆的核心处所发射的淡蓝色光芒。
Cherenkov radiation is predicted by the "standard model" of particle physics and is also observed in the real world, most often as a faint blue glow emanating from the cores of nuclear reactors.
