| 摘 要： | The δ Scuti star ctalogue is used to derive the observational locations of such stars on the HR diagram.The theoretical and observational instability strips are compared to check the theoretical red edge obtained by considering nonlocal time-dependent convection theory.The observational instability strip almost overlaps with the theoretical one,but the observed blue and red envelopes are hotter overlaps with the theoretical one,but the observed blue and red envelopes are hotter than the theoretical edges.The distribution of δ Scuti stars in the pulsation strip is not uniform.
