If the mass of the core after a supernova explosion is more than 1 . 4 but less than about 3 solar masses , then electron degenerate pressure is not strong enough to support the star . the star will contract to a size even smaller than the white dwarf . the electrons are squeezed into the nuclei and are combined with the protons to form neutrons 假若在超新星爆发后，剩馀核心质量介乎太阳质量的1 . 4至3倍，那么核心中的电子简并压力便再不足以抵抗强大的引力，恒星会进一步收缩，直至电子亦被挤压至原子核内，和质子结合成为中子。

At the seminar in the ancient city of cusco , the strong spiritual atmosphere of the local people was overwhelming . the 200 - seat venue was packed with more than 300 guests , some of whom occupied the stairways and crowded into the back . those who could not squeeze into the venue felt deep regret 在库斯科市cusco这个古文明的城市举办讲座时，我们感受到当地非常浓厚的灵修气氛，原先仅能容纳200人的会场，却挤进了300多人，连楼梯上都因坐满了人而无法通行，会场后面也站满了来宾，还有许多人无法进入场内而抱憾不已。
