摘要
假设超新星在坍缩过程中，当物质达到超核密度状态后，在临界密度下发生夸克相交．用ＷＷ（８８）初始模型在有夸克相交情形下对坍缩反弹和激波传播作了模拟，重点讨论了夸克相变对转移能量的影响．在适当的临界密度下发生夸克相交，可以增加转移能量从而得到更强的激波．
We assume that in a supernova collapse, when matter reaches the state of super nucleardensity, quark phase transition occurs under the critical density. We calculate the collapse,bounce and shock propagation using the WW(88) initial model. We discuss the influence ofphase transitions on the transferred energy and show that for suitable values of the criticaldensity, the phase transition can increase the transferred energy, leading to stronger shocks.
