You do get neat effects like cerenkov radiation ( that lovely nuclear reactor glow ) , but you ' re not violating causality or any of the other features of the light - speed limit because they ' re tied to the vacuum speed c 类似于契伦科夫辐射（核反应堆所发出的漂亮蓝光就由其产生）的奇妙效应确实存在，但你仍未打破光速的限制，因为所有这些速度最终都不能超过真空中的光速c 。
In this paper , the time property of its anode and dynode outputs has been studied and compared by using weak cherenkov light , the results show that their time resolution is dependent on the number of the electrons collected at the same conditions 为了获得多个倍增极的输出信号，对其进行了相应的改进，利用弱契伦科夫光，研究了其阳极和倍增极的时间特性，并作了比较，结果表明相同条件下它们的时间分辨与所收集的电子数有很大关系。
