and compare them with those in [@lin14]. The results are shown in Figure \[f4\]. Good consistency between the two approaches can be seen, demonstrating that our results are reliable.

In addition, the SFR-$M_*$ relation of star-forming field galaxies in our sample are fit with a linear formula, i.e. log$_{10}$(SFR/$M_{\odot}$ yr$^{-1}$) = $\alpha$ $\times$ log$_{10}$ ($M_*$/$M_{\odot}$) + $\beta$, where $\alpha$ and $\beta$ are fitting parameters for the slope and amplitude, respectively. We find that in our sample, the best-fit parameters are $\alpha$ = 0.63 $\pm$ 0.02 and $\beta$ = -5.77 $\pm$ 0.25 in the redshift range of 0.2 $< z <$ 0.5, and $\alpha$ = 0.62 $\pm$ 0.03 and $\beta$ = -5.59 $\pm$ 0.29 in the range of 0.5 $< z <$ 0.8. For comparisons, the best-fit parameters $\alpha$ and $\beta$ are 0.65 and -6.10 at $z$ = 0.42, and 0.62 and -5.62 at $z$ = 0.63 using Equation (1)$-$(3) from [@whi12] with a Chabrier IMF, where $z$ = 0.42 and 0.63 is the median redshift of our sample in the range of 0.2 $< z <$ 0.5 and 0.5 $< z <$ 0.8, respectively. In addition, the best-fit $\alpha$ and $\beta$ from [@noe07] are 0.67 $\pm$ 0.08 and -6.19 $\pm$
