目标。这项工作的目的是来推断恒星形成的属性和装配过程的高质量红移(0.3≤z 0.3,恒星形成率与恒星质量有关,这种关系似乎变陡峭和红移SFR的如果一个依赖的想法估计;b)的贡献全球SFRD通过大规模的星系随红移至2.5�,比低质量星系的更迅速,但似乎平高z;c)尽管有这种增加，但在任何z点上对SFRD最重要的贡献是大约或立即低于特征恒星质量的星系；
Aims. The goal of this work is to infer the star formation properties and the mass assembly process of high redshift (0.3 ≤ z 0.3, the star formation rate is correlated well with stellar mass, and this relationship seems to steepen with redshift if one relies on IR-based estimates of the SFR; b) the contribution to the global SFRD by massive galaxies increases with redshift up to � 2.5, more rapidly than for galaxies of lower mass, but appears to flatten at higher z; c) despite this increase, the most important contributors to the SFRD at any z are galaxies of about, or immediately lower than, the characteristic stellar mass;
