mass abundance 中文意思是什麼
mass abundance
解釋
質量豐度-
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。 -

The top sediment above 1. 8m depth was referred to be the deposit under the cold water mass since 9. 7kabp. in the middle southern yellow sea. q - mode factor analysis was employed on 98 samples and 33 benthic foraminiferous species with relative abundance of more than 2 % in at least 3 samples and 5 varimax factors had been recognized as follows : factor 1 ( ammonia beccarii vars
南黃海中部泥質區的ey02 - 2孔共揭示了氧同位素6期以來的海侵海退序列，該孔浮遊有孔蟲匱乏，說明黃海暖流對鉆孔所處南黃海中部冷渦泥質沉積區影響一直很弱，底棲有孔蟲中玻璃質殼占絕對優勢，比例為93 . 87 100 。 -

Our yields increase with the mass of the progenitor main - sequence stars. massive stars ( i. e. 18m < m < 50m ) is the primary sites of the neclearsynthesis of the r - process and can explain the galaxy chemical evolution. 3. we present formula to calculat the r - process galactic chemical evolution of ba peak elements. this formula contains metallicity abundance and point out the relation of the ba peak elements and disscuss the effect of various mass supersnova. besides, our formula can be confirmed by a lot of observations
由此可以解釋以下觀測事實: （ l ） mg ， eu均產生於snh星，但質量范圍不同，在高質量（ > 20 ） eu的產量高， mg的產量（相對于太陽） ，導致暈星中eu / mg > 0 ，而產生mg的質量范圍較大，致使在厚盤的晚期較小質量超新星也開始對mg有貢獻，而這些星對eu的貢獻很小，致使在厚盤星中eu / mg < 0 ，在厚盤中eu / fe隨金屬豐度的升高而降低，仁mg / fe隨金屬豐度的升高而不變 -
