helium burning 中文意思是什麼

helium burning 解釋
氦核燃燒
  • helium : n. 【化學】氦。 helium-4 氦4〈氦的最常見同位素〉。
  • burning : adj. 1. 燃燒的，像燃燒一樣的；灼痛的；辛辣的。2. 猛烈的，強烈的；熱烈的。3. 議論紛紛的；緊急的。4. 極惡劣的；明擺著的。n. 1. 燃燒。2. 燒制。3. 炎癥。
  1. Since the hydrogen - burning shell and helium - burning core do not produce energy in a stable and steady manner, the star will pulsate and generate strong stellar wind

    由於這時燃燒氫和氦以產生能源的過程並不穩定，星體除了會不斷脈動外，更會產生強勁的恆星風把外殼吹掉。
  2. After that it is expected to become a red giant, as the hydrogen that presently comprises it is exhausted and the sun switches to burning helium instead

    之後，據推測太陽會成變成一顆紅巨星，因為到那時候現在構成太陽的氫氣燃燒殆盡，太陽轉而燃燒氦氣。
  3. 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。
  4. 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。
  5. 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。
  6. 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

    由於大質量恆星的核心比一般恆星更熱和有更高的密度，當走至生命盡頭時，核心條件足以把氦繼續轉化為碳，同時在核心外圍形成一個氦殼。
