The relaxation effects induced by excitation (or ionization) of inner subshell electrons and their influences on the electronic wave functions of the ground configuration 3p6 and five excited configurations 1s-14s, 2s-14s, 2p-14s, 3s-14s, and 3p-14s in Argon have been systematically studied by using the Multi_configuration Dirac_Fock method (MCDF). Furthermore, the transition energies and probabilities of argon from kα and　kβ　lines have been presented and discussed in cases with and without relaxation, and also a comparison has been made with some existing theoretical calculations.
