Do not use the telescope to watch the laser rays, otherwise will be dangerous.
不要用望远镜观看的激光射线，否则将是危险的。
But all of the laser weapons, robots, sonic blasters and puke rays pictured here are real.
但这里提到的所有的雷射武器，机器人，音速爆破和催吐光线都是真实的。
By counting the number of such X-rays while scanning the frequency of the laser pulse, the team could make a very precise measurement of the photon energy required to drive the 2s-2p transition.
通过统计所发出X光的数量，然后对照激光脉冲的频率，测量小组能得出一个非常精确的测量值，从2s能级到2p能级跃迁所需的量子能量。
