对于将非重力与风味统一起来的规范组 [SU(6)[sup 3][times][ital Z][sub 3]，我们分析了世代跷跷板机制。在树级别，我们得到 [ital m][sub [nu][ital e]]=0 和 [ital m][sub [nu][tau]][类似于][ital m][sub [nu][mu]][类似于][ital M][sub [ital L]][sup 2]/[ital M][sub [ital H]]，其中 [ital M][sub [ital L]][类似于]10[sup 2] GeV 和 [ital M][sub [ital H]][ge]10[sup 5] GeV 分别是弱相互作用质量尺度和水平相互作用质量尺度。右手中微子的马约拉纳质量 [ital M][sub [ital R]] 的量级为 SU(2)[sub [ital R]] 破缺的量级。预测质量为 [ital M][sub [ital H]][sup 2]/[ital M][sub [ital R]] 量级的低能量奇异中性轻子。辐射校正可以产生 [ital m][sub [nu][ital e]][ne]0，比其他中微子质量小四个数量级。
For the gauge group [SU(6)[sup 3][times][ital Z][sub 3] which unifies nongravitational forces with flavors we analyze the generational seesaw mechanism. At the tree level we get [ital m][sub [nu][ital e]]=0 and [ital m][sub [nu][tau]][similar to][ital m][sub [nu][mu]][similar to][ital M][sub [ital L]][sup 2]/[ital M][sub [ital H]], where [ital M][sub [ital L]][similar to]10[sup 2] GeV and [ital M][sub [ital H]][ge]10[sup 5] GeV are the weak and horizontal interactions mass scales, respectively. The right-handed neutrinos get Majorana masses [ital M][sub [ital R]] of the order of the scale where SU(2)[sub [ital R]] is broken. A low energy exotic neutral lepton with a mass of the order of [ital M][sub [ital H]][sup 2]/[ital M][sub [ital R]] is predicted. Radiative corrections can produce [ital m][sub [nu][ital e]][ne]0, four orders of magnitude smaller than the other neutrino masses.
