摘要： Based on the multi-configuration Dirac--Fock method, this paper has made theoretical calculations for the dielectronic recombination cross-sections and the high-$n$ dielectronic satellites to K$\alpha$ resonance line in helium-like aluminium ions. It is found that high-$n$ dielectronic satellites are seriously mixed with resonance line, which leads to a significant increase in both the apparent width and the intensity of K$\alpha$ resonance line. They also induce a positional shift of K$\alpha$ resonance line.
