Art here coexists with the people , and accretes with chinese civilization too .

艺术与这块土地上的人民共存，艺术与中华文明共生。

Type ia supernovae occur in binary systems when one of the stars , a white dwarf , accretes just enough material from its companion to tip it over the chandrasekhar limit , the maximum mass a white dwarf can have before it collapses under its own gravity .

在这样的双星系统中，当双星中的一个，通常是白矮星，吸积它的伴星的物质超过钱德拉塞卡极限（白矮星在自身重力引起塌缩之前的最大质量）时，会产生ia型超新星。
