The Ca II H and K lines are employed to construct indicators for assessing and studying the chromospheric activity of solar-like stars. We investigate the widely used bolometric and photospheric calibrated chromospheric activity index $R'_{\\rm HK}$, derived from the method in the classic literature ($R'_{\\rm HK,classic}$) and the method based on the PHOENIX model ($R'_{\\rm HK,PHOENIX}$).
