molecular cloud

molecular cloud's meaning

Examples

  • 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。
  • The number density distribution of globular cluster in space will change with time due to the dynamic evolution , especially for those in the central region of the galaxy ; 5 . for the power law initial cluster mass function , the peak value of the mass function after the dynamic evolution is sensitive to the lower limit of the initial mass function we adopt . the suggested value in this paper is - 104m , which is consistent with that reduced from the dynamical analyses for the giant molecular clouds
    对于幂率的初始质量谱,球状星团系统动力学演化后质量分布的转折点质量主要是由初始质量函数的质量下限决定的,最为适合的值为10 ~ 4m _ ;幂率的初始质量谱的谱指数对球状星团系统动力学演化后质量分布的转折点质量也有影响,其最佳值为1 . 5 2 . 0 ;经过大约5gyr的动力学演化,幂率的初始质量谱就会演化成为高斯的对数质量分布并具有在随后的动力学演化中保持对数高斯形式质量分布的特性。
