氦星 的英文怎麼說
中文拼音 [hàixīng]
氦星
英文
helium star-
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。Their shells, which apart from hydrogen, helium, and carbon also contain portions of the heavy elements formed in the stellar core, are inherently unstable, and their pulsing creates a withering stellar wind a billion times stronger than the solar wind we know today
它的殼層除了氫層、氦曾和碳層外還有包含一部分產生自恆星核心的重元素，天生的不穩定，它們的脈動產生了一種毀滅性的星風，比我們現在知道的太陽風要強數百萬倍。It will quietly and steadily burn the hydrogen to helium and become a white dwarf
它會穩定地把氫轉化為氦，然後安靜的死去，成為白矮星。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。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？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。Extreme helium star
極端氦星The planets ' strong force of gravity holds huge amounts of hydrogen and helium gas
行星的巨大引力吸引了大量的氫氣和氦氣。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。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。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。Dr marcy suspects that his new discovery, which has about 45 times the mass of the earth, is composed of a rocky core surrounded by a thick envelope of hydrogen and helium gas
馬西博士懷疑，他的這個擁有地球質量四十五倍的新發現星體有一個巖層核心構成，並被一層很厚實的氫氣與氦氣層籠罩。Venus express has detected oxygen, hydrogen and helium ions ? remnants of early oceans ? escaping into space
金星快車已經發現了逃逸到太空的氧，氫和氦離子，他們是早期海洋的殘留物。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。Stars like the sun form when giant clouds of gas and dust condense into a ball, igniting thermonuclear fusion, which is the conversion of primarily hydrogen and helium into heavier elements
星喜歡太陽形式當氣體和塵土巨型雲彩凝聚進球，點燃熱核聚變，主要是氫和氦氣轉換入更重的元素。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。Mercury has a thin layer of atmosphere, which is mainly made up of sodium and a little helium
水星有一層由鈉和氦組成的極稀薄大氣，表面大氣壓力幾近於零。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
