gas halo 中文意思是什麼
gas halo
解釋
氣暈-
On the bases of the galaxy evolution theory, we use the therotical chemical evolution model of three zone ( such as halo, thick disk and thin isk ) and multi - phase ( diffuse gas, molecular clouds, stars of both low and high mass, the remnants ). by comparing with the observational constraints, such assurface densities, age - metallicity relation, g - dwarf metallicity distribution in the solar neighbourhood and the correlation between [ a / fe ] and [ fe / h ], supernovae rates, infall rates. the rationality of the model is verified. based on the theory model, we calculate the abundance of neutron capture element
本文正是在銀河系化學演化的基礎上，利用銀河系的三成分（ threezone ） （即暈、厚盤和薄盤）多相（ multi - phase ） （氣體，分子云，大、小質量恆星以及剩餘物質）的化學演化的理論模型，通過與觀測約束（質量面密度、場星的年齡-金屬豐度關系、太陽附近g矮星金屬含量分佈函數、三成份的特徵量、元素的星系化學演化、超新星的爆炸率、內落速率等）的比較，來檢驗模型的合理性。 -
In the case of the milky way, astronomers detected a huge, hot gas halo, or corona, that could be as much as 100, 000 light - years across, much bigger than earlier scientists theorized
以銀河系為例，天文學家檢測到一個巨大的熱氣日冕，它橫跨10萬光年，比先前科學家的理論推測要大許多。 -
Above and below the galactic plain, in which earth and our solar system reside, they detected an extremely thin, hot gas corona, or halo
在這上下居住著地球和我們的太陽系的星系平原上，科學家發現一種極薄的熱氣日冕。
