氦核燃燒 的英文怎麼說
中文拼音 [hàihéránshāo]
氦核燃燒
英文
helium burning-
When no hydrogen is left in the core, p - p chain reaction stops. remember that solar mass stars burn hydrogen through p - p chain producing helium, while stars more massive than 1. 1 solar masses undergo the cno cycle
當核心氫氣燃燒殆盡之後，質子質子鏈便會停止還記得約相等於一個太陽質量的恆星是用質子質子鏈把氫原子核轉化為氦原子核嗎？All red giants are variable stars. the core keeps on contracting and heating up until it is hot enough for the
所有紅巨星都是變星，當外殼不斷膨脹，氦核心同時不斷收縮加熱，直至足以燃燒氦我們稱之為When helium burning takes over the main burden of energy generation in the star, the core expands somewhat, and the envelope contracts somewhat.
當氦燃燒成為星體能量產生的主要來源時，核心略微膨脹，而包層略微收縮。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
我們採用單脈沖中子源『 zne （ a ， n ） zsmg ，採用最新發表的中子俘獲截面，用中心氦燃燒模型計算了各金屬豐度情況下15m m叼0m 。的大質量星的s過程核合成，並將所得結果與太陽的s刁分量進行比較。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
情況很像燃燒氦，強大的引力足以在核心燃點起碳，而同時維持星體穩定。核心物質不斷聚變為更重的元素，直至成為鐵。分享友人
