当核燃烧向外进行到核心周边壳层的新物质时，恒星会膨胀成所谓的红巨星。
This causes a drop in pressure that makes the star unstable and causes it to contract under its own weight. Eventually the process ignites runaway nuclear reactions that rip the star apart.
这引会起压强的突降，使得恒星不稳定并在自己的重力下收缩。最终这个过程引发了雪崩式的核反应并将恒星斯裂开。

This stirs up hydrogen fuel and causes the growing star to undergo nuclear fusion at a faster rate.
这煽起氢燃料及原因进行不断增长的星核融合的速度在加快。
As the study of properties of warm asymmetric nuclear matte may shed a light on the study of neutron star, the liquid-gas phase transition of warm asymmetric nuclear matte is investigated.
由于对于非对称核物质性质的研究有助于对中子星物质的认识，考察了非对称致密热核物质的液—气相变。
When the core of a giant star whose mass surpasses 1.4 times the present mass of our Sun exhausts its nuclear fuel, it is unable to support its own weight and collapses into a tiny neutron star.
当一颗质量超过我们的太阳目前质量1.4倍的巨星的内核耗竭其核燃料时，它便无法支撑自身的重量，并收缩成为一颗小型中子星。
