average abundance 中文意思是什麼
average abundance
解釋
平均豐度-
The average abundance distributions of heavy elements in metal - poor stars can provide fairly direct and detailed information on the nucleosynthesis in every stage after the formation of galaxies. furthermore, it can put more accurate constraints on the chemical evolution of neutron - capture elements. the solution to this problem will have important effect on the solution to a series of problems about nuclear astrophysics and the galactic evolution
貧金屬星的中子俘獲元素豐度分佈能提供星系形成后各個階段核合成的較為直接和詳細的信息，並為星系化學演化的研究提供更為準確的約束，這一問題的解決將對核天體物理及星系化學演化的一系列問題的解決產生重要影響。 -
3 abundance of microzooplankton hi jiaozhou bay varied significantly among sampling stations during the survey period. in general, high densities of microzooplankton appeared in water bodies of the inner bay, low densities were recorded at estuary and outer part of the bay. the highest annual average densities was recorded at station 3 ( 346. 45 ind. / l ), the lowest at station 10 ( 55. 54 ind. / l )
3 、在不同采樣站，小型浮遊動物豐度差異明顯，灣內較高，灣口和灣外較低，年平均最高和最低密度出現於3號站和10號站，分別為346 . 45個升和55 . 54個升不同水層，小型浮遊動物豐度差異不明顯。 -
Thus the cumulative consequence of galactic chemical evolution starting from low metallicity agb stars, namely, the average abundance patterns of sbh part with 140a204 ( or the snl component part with 92a132 ) in different metal conditions, should be similar ( ornearly similar ) to the corresponding solar s - bajn component
低金屬豐度條件下，由於中子輻照量隨金屬豐度的降低而升高， s _ （ ml ）產量低於s _ （ mh ） 。雖然s _ （ ml ）分佈與太陽系有差異，但對于質量范圍92 a 132 ，任何金屬豐度下分佈與太陽系大體相似。
