The lepton number is generalized to the leptoncharge.
我们把轻子数推广为轻子荷。
2
The quarks have not only baryon number and charge but also leptoncharge.
夸克不仅带有重子数、电荷,而且也带有轻子荷。
3
It is proved that only leptoncharge is strictly conserved and the individual conservation of the lepton number of every generation of leptons hold only approximately.
