 this work, with the help of chemical evolution and SFH\u00a0 from chemical  evolution model and pan-spectral\u00a0 energy distribution data,\u00a0 we break  the SFR-age-metallicity degeneracies. <span style=\"color: #ff0000;\">But  the parameter degeneracies can not completely removed, especially more  properties, therefore more parameters, are studied in SED modeling.<\/span> On the other hand, to avoid an ad hoc parameter space, the stacked SED is only able (worth) to derive average properties.<span style=\"color: #ff0000;\"> In the sense that we will not give ad hoc parameters but the general  properties of this population with modeling the stacked
