摘要本文综述了超新星（SN）喷出物的发射过程。应用的理论观测数据的例子。SN喷出物内的发射过程和热条件随时间而变化，多历元观测对于获得全面的看法是重要的。通过分析，我们可以约束原始半径、成分随深度的变化、喷出物的性质、爆炸的不对称性等;多频跟踪也很重要，包括射电同步辐射和逆康普顿效应，新合成材料放射性衰变产生的γ射线辐射。光学数据对于充分利用多频数据至关重要。
Abstract We review emission processes within the supernova (SN) ejecta. Examples of the application of the theory to observational data are presented. The emission processes and thermal condition within the SN ejecta change as a function of time, and multi-epoch observations are important to obtain comprehensive views. Through the analyses, we can constrain the progenitor radius, compositions as a function of depth, ejecta properties, explosion asymmetry and so on. Multi-frequency follow-up is also important, including radio synchrotron emissions and the inverse Compton effect, γ-ray emissions from radioactive decay of newly synthesized materials. The optical data are essential to make the best use of the multi-frequency data.
