in this paper, we investigate the asymptotic expressions of the elementary spherical functions on the non-compact Riemannian symmetric spaces of ranks one, and use the heat kernel obtained by Lohoue and Rychner to establish the central limit theorem for these spaces, our conclusion includes Terras theorem as a special case.
