摘要: Using the two volume-limited main galaxy samples of Sloan Digital Sky Survey Data Release 7, we explore environmental dependence star formation rate (SFR), specific (SSFR) and stellar mass for blue red galaxies. It is found that SFR, SSFR galaxies still fairly strong, but these parameters very weak. Our analyses suggest strong mainly a result in late-type sample. results also show SFR depend on its environment as well colour.
