One way to create such short bursts of gamma rays is through the collision — and subsequent annihilation, as the mass of those particles converts into energy — of an electron and a positron.
制造伽马射线短脉冲的一种方法，是电子与正电子的碰撞——之后的湮灭，使粒子的质量转化为能量。
These would stand out against the background noise not because they are precisely centered on a particular wavelength, but because they are very short and punctuated bursts of energy.
这种会在背景噪声中引人注意的并不是因为他们明确的集中于某一特定波长，而是因为他们在很短的点状爆发能量。
Every week, astronomers sight two or three gamma ray bursts (GRBs), short flashes of high-energy radiation from collapsing stars.
天文学家们每周都能看到两三次伽马射线爆发(GRBs)现象，这种现象是恒星塌缩时产生的高能辐射所造成的短暂闪光。
