helium burning meaning in English
氦核燃烧
Examples
- When helium burning takes over the main burden of energy generation in the star, the core expands somewhat, and the envelope contracts somewhat .
当氦燃烧成为星体能量产生的主要来源时，核心略微膨胀，而包层略微收缩。 - Similar to the helium burning , the strong gravitational force of the star ignites and controls the carbon burning in the core ; light nuclei fuse into heavier and heavier elements , until iron
情况很像燃烧氦，强大的引力足以在核心燃点起碳，而同时维持星体稳定。核心物质不断聚变为更重的元素，直至成为铁。 - Because of the large mass , after the hydrogen burning , the temperature and pressure of the core is high enough to trigger helium burning to carbon , and a hydrogen burning shell is developed around the core
由于大质量恒星的核心比一般恒星更热和有更高的密度，当走至生命尽头时，核心条件足以把氦继续转化为碳，同时在核心外围形成一个氦壳。 - Adopting single pulse neutron exposure 22ne ( a , n ) 2dmg and the updated neutron cross section , making use of the core helium burning model of the single neutron exposure theory , we calculate the s - process nucleosynthesis in massive stars at different mettalicity and compare the results with the solar s - weak component
我们采用单脉冲中子源‘ zne （ a ， n ） zsmg ，采用最新发表的中子俘获截面，用中心氦燃烧模型计算了各金属丰度情况下15m m叼0m 。的大质量星的s过程核合成，并将所得结果与太阳的s刁分量进行比较。
