Abstract：
Polarized deep inelastic scattering is a powerful tool for studying the internal refined information about the parton structure of the proton and deuteron. By means of the spin-dependent quark distributions in 6-quark clusters extended from a pQCD model, the polarized structure function of deuterons is investigated. Nuclear effects due to the presence of spin-1 isosinglet 6-quark clusters in the deuteron is obtained. It can be found that the calculated results with nuclear effects can better fit the SLAC E155 experimental data than that without nuclear effects.
