英文摘要	With t-channel rho, f(2)(1270) exchange and the pipi --> rhorho --> pipi box diagram contribution, we reproduce the pipi isotensor S-wave and D-wave scattering phase shifts and inelasticities up to 2.2 GeV quite well in a K-matrix formalism. The t-channel rho exchange provides repulsive negative phase shifts while the t-channel f(2)(1270) gives an attractive force to increase the phase shifts for pipi scattering above 1 GeV, and the coupled-channel box diagram causes the inelasticities. The implication to the isoscalar pipi S-wave interaction is discussed. (C) 2004 Elsevier B.V. All rights reserved.
