metal abundance
metallicity
Example Sentences:
1.The abundance of feed nuclei 6fe of s - process is proportional to metalicity
Fe族元素作为种子核,金属丰度与[ fe h ]成正比。
2.2 . the abundance distributions of the sbl component part with 92 a132 are nearly similar to the solar pattern at any metallicity
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相应分量大体相似。
3.Consequently the distributions of the corresponding solar s , h component is typical and can serve as a standard pattern in investigating the abundance distribution of neutron capture elements at any metallicity
因而太阳系的s _ ( ml )的88 a 138部分可以近似做为任何金属丰度情况下的标准丰度分布模式。一s
4.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
本文正是在银河系化学演化的基础上,利用银河系的三成分( threezone ) (即晕、厚盘和薄盘)多相( multi - phase ) (气体,分子云,大、小质量恒星以及剩余物质)的化学演化的理论模型,通过与观测约束(质量面密度、场星的年龄-金属丰度关系、太阳附近g矮星金属含量分布函数、三成份的特征量、元素的星系化学演化、超新星的爆炸率、内落速率等)的比较,来检验模型的合理性。
5.Adopting single pulse neutron exposure 22ne ( a , n ) 2dmg and the updated neutron cross section , making use of the core helium burning model of the single neutron exposure theory , we calculate the s - process nucleosynthesis in massive stars at different mettalicity and compare the results with the solar s - weak component

6.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
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。
7.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
由此可以解释以下观测事实: ( l ) mg , eu均产生于snh星,但质量范围不同,在高质量( > 20 ) eu的产量高, mg的产量(相对于太阳) ,导致晕星中eu / mg > 0 ,而产生mg的质量范围较大,致使在厚盘的晚期较小质量超新星也开始对mg有贡献,而这些星对eu的贡献很小,致使在厚盘星中eu / mg < 0 ,在厚盘中eu / fe随金属丰度的升高而降低,仁mg / fe随金属丰度的升高而不变
