摘　　要：Regarding the weak hypercharge y in the standard model as a non-foundamental quantum number and decomposing it as the sum of three kinds of lepton numbers l_(1),l_(2),l_(3),the baryon number b and the weak strange number s,we obtain an electroweak model with symmetry group SU(2)_(L)×U(1)_(l1)×U(1)_(l2)×U(1)_(l3)×U(1)b×U(1)s,where five neutral weak vector particles arise,with one of them being the same as Z^(0) in the standard model and the other four being the new Z's.
