A relativistic multi configuration interaction model is used to study the dielectronic satellite transition of 4d～2p resonance lines for Ne like Kr ions. The line wavelength and satillite intensity factor was calculated in detail. A simple kinetics model was developed, which agree well with the mearured spectra, and we found that the satellites position and strengths were strongly influenced by CI effect. On the theoretic side, configuration mixing among same complex configurations must be included in the calculation of the transition data.
