摘      要：We propose a method to construct new quantum integrable *** an example,we construct an integrable anisotropic quantum spin chain which includes the nearest-neighbor,next-nearestneighbor and chiral three-spin *** is shown that the boundary fields can enhance the anisotropy of the first and last bonds,and can induce the Dzyloshinsky–Moriya interactions along the z-direction at the *** using the algebraic Bethe ansatz,we obtain the exact solution of the *** energy spectrum of the system and the associated Bethe ansatz equations are given *** method provided in this paper is universal and can be applied to constructing other exactly solvable models with certain interesting interactions.
