The MIT quark bag model is used to determine the thermodynamic characteristics of hot strange quark matter that is opaque to neutrinos. Three different variants of the lepton content of hot quark matter are considered. The numerical calculations are done for different temperatures and lepton charge densities. It is shown that in hot (kT~100 MeV) quark matter there are roughly as many neutrinos as massive leptons, the total energy of the leptons is 4-20 percent of the energy of the quarks, and during cooling an energy on the order of 30-40 percent of the total energy is released.

中微子约束热夸克物质的特性

麻省理工学院夸克袋模型用于确定对中微子不透明的热奇夸克物质的热力学特性。考虑了热夸克物质轻子含量的三种不同变体。数值计算是针对不同的温度和轻子电荷密度进行的。结果表明，在热（kT~100 MeV）夸克物质中，中微子的数量大致与大质量轻子一样多，轻子的总能量是夸克能量的4-20%，在冷却过程中，能量约为释放了总能量的 30-40%。
