本文报道了我们首次尝试在格点QCD中确定包含自旋轨道力的奇偶奇扇区中的NN势，采用了通过Schr odinger方程从Nambu-Bethe-Salpeter（NBS）波函数中成功地提取奇偶偶NN势的方法.在16^3 × 32格点上，利用Nf = 2的CP-PACS规范组态，在a = 0.16 fm，m_\pi \cong 1.1 GeV的条件下，计算了宇称奇扇区的中心势、张量势和自旋轨道势.虽然统计误差仍然很大，我们观察到，这些潜在的定性特征大致同意的唯象势。
In this paper, we report our first attempt at determining NN potentials in the parity odd sector including the spin-orbit force in lattice QCD, employing the method to extract successfully parity even NN potentials from Nambu-Bethe-Salpeter (NBS) wave functions through the Schr\"odinger equation. Using Nf = 2 CP-PACS gauge configurations on a 16^3 x 32 lattice at a = 0.16 fm and m_\pi \cong 1.1 GeV, we calculate central, tensor and spin-orbit potentials in the parity odd sector. Although statistical errors are still large, we observe that the qualitative features of these potentials roughly agree with those of phenomenological potentials.
