average abundance meaning in English
平均丰度
Examples
- 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
低金属丰度条件下，由于中子辐照量随金属丰度的降低而升高， s _ ( ml )产量低于s _ ( mh ) 。虽然s _ ( ml )分布与太阳系有差异，但对于质量范围92 a 132 ，任何金属丰度下分布与太阳系大体相似。 - 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
贫金属星的中子俘获元素丰度分布能提供星系形成后各个阶段核合成的较为直接和详细的信息，并为星系化学演化的研究提供更为准确的约束，这一问题的解决将对核天体物理及星系化学演化的一系列问题的解决产生重要影响。
