Besides supernova remnants, these shock models are important in understanding a wide range of astrophysical phenomena, ranging from winds in newly-formed stars to cataclysmic stellar outbursts.
除了残骸，这些冲击波模型对于了解一系列天体物理学现象，从新恒星上的气体流动到恒星物质的喷发，有很重要的帮助。
Indeed, Cheng expects that the energy of the shock front at the galactic centre is nearly 100 times greater than that created by a supernova explosion.
确实，Cheng预计银河中心激震前沿的能量将近是超新星爆发产生的能量的一百倍。
This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant.
这种激波会导致形成一个膨胀的气体和尘埃构成的壳状结构，这被称作超新星遗迹。
