SO（10）模型中有一个{\bf 10}和一个{\bf 126}希格斯标量，在没有其他希格斯标量的情况下，能给出夸克和轻子的质量和混合吗？最近，至少对夸克和带电轻子来说，已经证明这是可能的。然而，对于中微子，通常认为由夸克和带电轻子质量确定的参数不能给出观测到的大中微子混合。系统地研究了这个问题，得出的结论是，尽管目前的数据不能给出数据的最佳拟合值，但不能排除带有两个希格斯标量的SO（10）模型。
Can the SO(10) model with one {\bf 10} and one {\bf 126} Higgs scalars give the observed masses and mixings of quarks and leptons without any other additional Higgs scalars? Recently, at least, for quarks and charged leptons, it has been demonstrated that it is possible. However, for the neutrinos, it is usually said that parameters which are determined from the quark and charged lepton masses cannot give the observed large neutrino mixings. This problem is systematically investigated, and it is concluded that the present data cannot exclude SO(10) model with two Higgs scalars although it cannot give the best fit values of the data.
