讨论了中微子在II型超新星中的作用。从理论上对中微子的光度作了全面的估计。从它们如何交换能量、动量和轻子数的角度来评估所涉及的不同弱相互作用。特别注意的是熵的产生，热和化学平衡的途径，以及捕获现象。考虑了计算中微子流的各种方法。这些方法包括捕获和泄漏方案、分布平均传输和多能量组方法。从超新星1987a捕获的中微子中获得的信息被简要地评估。
The role of neutrinos in Type II supernovae is discussed. An overall view of the neutrino luminosity as expected theoretically is presented. The different weak interactions involved are assessed from the standpoint of how they exchange energy, momentum, and lepton number. Particular attention is paid to entropy generation and the path to thermal and chemical equilibration, and to the phenomenon of trapping. Various methods used to calculate the neutrino flows are considered. These include trapping and leakage schemes, distribution-averaged transfer, and multi-energy group methods. The information obtained from the neutrinos caught from Supernova 1987a is briefly evaluated.
