In fact, the integrated peculiarities of ssSSPs are various from those of stellar populations with binary interactions (bsSSPs). Therefore, it is necessary to investigate the effects of binary interactions on the Lick indices and colours of populations detailedly. We show some formulae for calculating the difference between the Lick indices and colours of bsSSPs, and those of ssSSPs.
