【摘要】 本文提出了一个对称性破缺前不仅左、右对称,而且中微子（或反中微子）与荷电轻子、反轻子的弱作用也相同的SU（3）×U（1）模型。这一模型无三角反常;导出了sin²θ_w≤1/4;在低能范围内与标准模型一致。我们把轻子数推广为轻子荷。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。夸克不仅带有重子数、电荷,而且也带有轻子荷。本模型预言有μR→eR+ν_eL+V_μR^c,e^-+e^-→μ^-+μ^-等现象。更多还原

【Abstract】 An electro-weak unified model based on SU（3）×U（1） group is suggested, which is left-right symmetrical and assuming the same interactions of neutrinos （or antineutrinos） with charge leptons and antileptons before spontaneous symmetry breaking. It is anomaly free and sin² θ_w≤1/4 can be drived. The difference between the model and the Weinberg-Salam model is very small in the low energy range. The lepton number is generalized to the lepton charge. It is proved that only lepton charge is strictly conserved and the individual conservation of the lepton number of every generation of leptons hold only approximately. The quarks have not only baryon number and charge but also lepton charge. This model predicts processes μ_R^-→e_R^-+v_eL+v_μR^c+e_L^-+e_R^-→μ_L^-+μ_R^-,etc.更多还原
