Abstract：
The spin-orbit interactions between two quarks due to the one-gluon exchange,the confinement potential, the σ exchange of chiral field and the twogluon exchange are all considered in our calculation. As a consequence the spin-orbit splitting of 1P state in the baryon spectrum and the 3P2 phase shifts of the N-N scattering can be well explained simultaneously.
