Abstract：
A composite model with the gauge group SU(3)_sc×SU(6) is proposed to explain the family problem.Quarks and leptons are composed of two kinds of massless spin-1/2 preons.Applying Fermi principle and 'tHooft consistency conditions to supercolor-singlet preon composite systems,three generations of quarks and leptons,as required by the experimental observations and the expectation of the Big Bang theory are constructed.Weak bosons are also composed of the same set of preons.This model interprets the low energy weak interaction and does not leads to any difficulty of proton decay.
