在脉冲射线束测量中，射线以束流形式作用在探测器上，输出电流是许多射线粒子同时作用的叠加效果。
When the waveform of a radiation pulse is measured, a large number of radiation particles interact with the detector simultaneously.
从可见光扩展到无线电波，再到 X 射线和伽马射线，天文学总是会发现不寻常的物体，如射电星系、类星体和脉冲星。
The extension of astronomy from visible light to radio waves to x-rays and gamma rays never failed to lead to the discovery of unusual objects such as radio galaxies, quasars, and pulsars.
费米太空望远镜对这些伽马射线脉冲很灵敏，以至于它甚至不需要调整位置对准雷暴的正上方，就能来探测TGF信号。
The Fermi Space Telescope is so sensitive to these gamma ray bursts that it doesn't even need to be positioned right over a thunderstorm to detect the TGFs.
