helium star 中文意思是什麼

helium star 解釋
氦星
  • helium : n. 【化學】氦。 helium-4 氦4〈氦的最常見同位素〉。
  • star : n 1 星；【天文學】恆星 （opp planet）。2 星狀物，星（形勛）章。3 【印刷】星形號〈 〉。4 【占星術...
  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. At the end of the process a carbon core of the star will be surrounded by a shell where helium is still being fused into carbon, which in turn is surrounded by and envelope where hydrogen is converted into helium

    該過程結束時碳的星核會被一層仍然在進行氦聚變為碳的殼層包圍，而在這個氦-碳聚變層的外面還包圍著一層由氫-氦聚變層。
  3. The helium core of the star starts to collapse. this gravitational contraction will heat up the hydrogen envelope surrounding the core. fusion therefore begins in the envelope and the star expands

    剩下的氦核心便會開始塌縮並產生熱，緊鄰核心的氫外殼會被加熱而開始有熱核反應恆星亦同時膨脹。
  4. Extreme helium star

    極端氦星
  5. Astronomers ascribed them to thermonuclear fusion of hydrogen or helium or to the sudden accretion of matter onto the star

    天文學家因此可將其歸因於氫或氦的熱核融合反應，或是有物質突然被星體吸附而產生的。
  6. The star used to be like the sun, a “ main sequence ” star that burns hydrogen by nuclear fusion, producing helium

    該恆星和太陽一樣是一顆主星序恆星，氫元素通過核裂變生成氦元素。
  7. 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。
  8. When the hydrogen in the shell, too, is exhausted, the star takes to fusing helium there

    當殼層中的氫也燃燒殆盡，恆星便開始融合氦。
  9. 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。
  10. The helium will burn steadily and the higher energy production rate will heat up the star. the star will swell to a size even larger than a red giant and we have a

    在恆星強大質量的約束下，核心氦聚變成碳的過程能穩定地進行，在核心高熱的煎熬下，恆星外殼會極度膨脹成為比紅巨星更巨大的
  11. When a star is at the main sequence stage, its interior continuously fuses four hydrogen nuclei i. e. protons into one helium nucleus

    在主序星階段，恆星內部不斷把四粒氫原子核即質子融合成一顆氦原子核。
  12. Which turns four hydrogen nuclei to a helium nucleus. the star will have a convective shell and a radiative core just like our own sun see

    進行，將四顆氫原子核結合為一顆氦原子核，恆星會有輻射核心和一個對流外殼就像我們的太陽。
  13. Helium - strong star

    強氦線星
