英文摘要	The quark effect in the two baryon systems is studied by making an analysis of the quark exchange terms. The results point out that the quark effect becomes visible only when the two baryon clusters are close to each other. So its influence is much more important in the S waves than in P waves, and the expectation value of the permutation operator in the spin-flavor-color space plays significant role. For some spin-flavor states, the Pauli Blocking Effect is very serious, there should be a big repulsive core radius between these two baryons. But for some other spin-flavor states, the quark exchange effect is favorable for mixing the two baryon clusters together to form dibaryon. Therefore the data of the phase shifts of the baryon-baryon scattering and the binding energies of the two baryon systems are cardinal in examining the quark effect.
