英文摘要	The explicit expressions for calculating the in-medium N+N-->Delta+Delta and Delta+Delta-->N+N cross section have been derived within the framework of the self-consistent relativistic Boltzmann-Uehling-Uhlenbeck approach in which the deltas and nucleons are treated on an equal footing. The obtained cross sections are consistent with the other integrands of the transport model. The theoretical prediction of the free double-Delta production cross section is in good agreement with the experimental data. All the medium effects on the double-Delta production and absorption cross section are studied systematically, and strong medium corrections are found. Our numerical results show that it would be important to take the N+N-->Delta+Delta and Delta+Delta-->N+N channel into account in the study of relativistic heavy-ion collisions at intermediate and high energies.
