The radiative seesaw mechanism of Witten generates the right-handed neutrino masses in SO(10) with the spinorial 16(H) Higgs field. We study here analytically the 2nd and 3rd generations for the minimal Yukawa structure containing and Higgs representations. In the approximation of small 2nd generation masses and gauge loop domination we find the following results: (1) beta-tau unification, (2) natural coexistence between large theta(l) and small theta(q), and (3) degenerate neutrinos.
维滕的辐射跷跷板机制利用旋量16（H）希格斯场在SO（10）中产生右手型中微子质量。我们在此解析地研究包含希格斯表示的最小汤川结构的第二代和第三代。在第二代小质量和规范圈主导的近似下，我们得到以下结果：（1）β-τ统一，（2）大θ（l）和小θ（q）之间的自然共存，以及（3）简并中微子。
