中文摘要：
分析了超新星中从两味夸克物质到奇异夸克物质相变的u，d夸克质量作用，研究表明，相变平衡后，u，d夸克质量对夸克丰度、温度和中微子总能量的影响不大．在分析相变过程时，u，d夸克的质量可以忽略．进一步表明，夸克味（u，d）不是好的量子相变参量．光子的夸克结构模型也得到了支持．
英文摘要：
The effect of u and d quark mass on the conversion of the two - flavor quark matter to more stable strange quark matter has been analyzed. It is shown that the u and d quark mass has slight influence on equilibrium parameters, involving quark temperature, quark abundances and total neutrino energies. So the u and d quark mass can reasonably be neglected when the conversion processes are studied in a supernova core. It further indicates that the u, d quarks are not good quantum transition flavors and the structure of photon comprised of quarks is also supported.
