Abstract：
Color singlet set and color string configuration among partons for multiparton system are analyzed from exact SU _c(3). The probability for singlet string, which corresponds to color dipole in Lund CD model, is found to decrease rapidly as the number of gluons increases, while for those singlet clusters whose color structure are similar to glueballs, their probability grows rather fast and is independent of strong coupling constant. This phenomenon is thought to be a kind of collective effect.
