利用数值对角化方法研究了具有单离子各向异性和双二次相互作用的S= 1反铁磁链的磁化过程。这两种相互作用稳定的2-磁振子Tomonaga-Luttinger液体（TLL）在磁化过程中的阶段。根据数值对角化方法计算出的几个激励间隙，给出了磁化过程的相图。这些相图表明，自旋自旋主导的TLL相出现在较高的磁化足够大的负D。
The magnetization process of the S= 1 antiferromagnetic chain with the single-ion anisotropy D and the biquadratic interaction is investigated using the numerical diagonalization. Both interactions stabilize the 2-magnon Tomonaga-Luttinger liquid (TLL) phase in the magnetization process. Based on several excitation gaps calculated by the numerical diagonalization, some phase diagrams of the magnetization process are presented. These phase diagrams reveal that the spin nematic dominant TLL phase appears at higher magnetizations for sufficiently large negative D.
