The leptonnumber is generalized to the lepton charge.
我们把轻子数推广为轻子荷。

It is proved that only lepton charge is strictly conserved and the individual conservation of the leptonnumber of every generation of leptons hold only approximately.
证明了只有轻子荷才是严格守恒的,各代轻子数分别守恒只能近似成立。

The quarks have not only baryon number and charge but also lepton charge.
