摘要	By studying the anisotropy of EPR g factors (characterized by Deltag = g(perpendicular to) - g(\)) for Ni3+ ions created by X-ray irradiation of nickel-doped Rb1-xCsxCaF3 mixed perovskites in cubic-to-tetragonal phase transition, the local order parameters phi with x = 0.1, 0.21, 0.27 and 0.35 in the tetragonal phase (T = 25 K) are obtained. From the evaluation of phi with x and the expression phi = phi(0)\T - T-C\(beta), it is found that the decrease of phi with increasing concentration x is due mainly to the decreases of T-C and phi(0) with increasing concentration x.
