研究了一维可积自旋轨道模型。在大自旋极限下，自旋部分的自由度可以用经典的I Sing自旋来描述。在没有外部磁场的情况下，系统的基态是具有伊辛反铁磁自旋序背景的连通轨道液体。基本激发是常见的类自旋轨道量子。在外部磁场中，系统中存在磁通相。通量（两个平行的自旋）将系统切割成不相连的轨道液体（域）。
A one-dimensional integrable spin-orbital model is studied. In the large spin li mit, the degrees of freedom of the spin part can be described by the classical I sing spins. Without the external magnetic field, the ground state of the system is a connected orbital liquid with the background of Ising antiferromagnetic ord er of spins. The elementary excitations are the usual spinon-like orbital quanta . In an external magnetic field, flux phase exists in the system. The fluxes(two parallel ising spins)cut the system into disconnected orbital liquids(domains).
