金属丰度 meaning in English
metal abundance
metallicity
Examples
- 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 . 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。 - 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 - 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。 - 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
我们采用单脉冲中子源‘ zne （ a ， n ） zsmg ，采用最新发表的中子俘获截面，用中心氦燃烧模型计算了各金属丰度情况下15m m叼0m 。的大质量星的s过程核合成，并将所得结果与太阳的s刁分量进行比较。
