初始质量函数

利用Miller-Scalo初始质量函数计算银晕的化学演化

Calculating the chemical evolution of galactic halo with Miller-Scalo initial mass function

研究表明，这些恒星不可能通过恒星形成率和初始质量函数均不随时间变化的单一恒星形成模式产生。

No single star formation mode with a constant star formation rate ( SER ) and an invariable initial mass function ( IMF ) can fit the observations of globular clusters .

简单总结了星系演化的两个基本参数：初始质量函数（IMF）和恒星形成速率（SFR），以及讨论了红外观测在这两个参数研究中的贡献。

Two main parameters for studying galactic evolution-initial mass function ( IMF ) and stellar formation rate ( SFR ) are summarized . Their research situation as well as significance of the large scale infrared observations in studying these parameters is discussed .

我们选取的合理的参数，如金属产率，恒星初始质量函数等使得我们能预言星系颜色分布的双峰结构。

Also the reasonable model parameters , such as the metal yield and the stellar initial mass function , make it possible to re-produce the observed bimodal distribution of the color-magnitude diagram .
