disk of galaxy 中文意思是什麼

disk of galaxy 解釋
星系盤
  • disk : n 1 圓盤；盤狀，盤狀物。2 【體育】鐵餅；〈美國〉唱片。3 【植物；植物學】花盤；【動物；動物學】盤...
  • of : OF ＝Old French 古法語。
  • galaxy : n. 1. 〈the G-〉 銀河；銀河系；〈pl. 〉 河外星系。2. 人才薈萃，一群顯赫的〈出色的〉人物；一系列光彩奪目的東西。
  1. The disk of stars thickened considerably in the region of resonance, giving the inner regions of the galaxy a boxy or a peanut shape

    在共振區域的星盤增厚許多，使得星系內部區域成為盒子狀或花生狀。
  2. 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。
  3. Whether an entire galaxy becomes a disk is a timing issue : spiral galaxies emerge from gas that becomes rotationally supported before patches of the gas contract into stars

    至於整個星系變成一個圓盤則是時機問題：螺旋星系的出現，是因為在每一小團氣體因收縮而形成恆星前，整團氣體已經成為旋轉性支撐。
  4. Clouds of stars and glowing gas, with patches of darkening dust, mark the slow - changing spiral patterns of the galaxy disk

    點綴著暗淡塵埃的團團恆星和發光星雲，標記著銀河系緩慢變化的旋渦外形。
  5. The galaxy ' s central region is called the galactic bulge because the stars form a ball a few thousand light years in diameter that extends above and below the disk of the galaxy

    星系的中心區域叫做核球，原因是恆星組成了直徑幾千光年的球體，膨脹到星系盤上下兩側。
  6. For the galaxy, a model contained three components ( bulge, disk and halo ) suggested by paczynski ( 1990 ) is adopted, which can reproduce most of the global observational properties of the milky way such as the rotation curve

    動力學演化的時間取為銀河系球狀星團的平均年齡12gyr 。我們採用了三成分（核球、盤、暈）的銀河系模型（ p90 ） 。
  7. Optical light from stars ( yellow - green / hubble space telescope ) shows the disk of a modest - sized, apparently normal galaxy

    來自恆星的可見光（圖中為黃/綠色，哈勃太空望遠鏡拍攝）顯示出的是一個中等大小、外觀正常的星系盤。
  8. Another prominent feature of the milky way galaxy is the spiral arms. they consist of young stars extending from the center to the edge of the disk

    銀河系另一個重要的特徵便是它的旋臂，這些旋臂由中心延展至銀盤邊緣，包含了無數年青的恆星。
