摘要	The EPR zero-field splitting D, the anisotropic g factors gli,gi, the first excited (E-2) State splitting Lambda and the stress dependences of D and Lambda for V2+ ion in Al2O3 crystal have been calculated from the high-order perturbation formulas and the superposition model. It is found that to reach the good fit between calculation and experiment for these EPR and optical data, the local lattice relaxation and the local strain in the vicinity of V2+ ion in Al2O3 should be taken into account. These local values are estimated and the results are discussed.
