A chiral hadronic model is extended to investigate antikaon condensation and hyperons production of protoneutron stars.

摘要用相均场下的手徵强模型研究了前中星(均值)K凝聚和超的生成。

It turns out that the weak interaction causes a kaon gradually to convert into its antiparticle, the antikaon, and then back again.

弱交互作用会k逐渐变成反粒──反k，然后又变回来。
