Abstract：
Employing instantaneous Bethe-Salpeter equation and taking into account the correction of negative energy component of Dirac spinor to one-gluon exchange interaction,the calculation of the △,N baryon spectra is carriedout.We find that the effect changes the potential parameters significantly,but leaves the global structurs of spectrum almost untouched.
