For a finite chain, the Bethe Ansatz equations(BAE) are very complicated. In terms of q-deformation Young operators this Hamiltonean system can be reduced to a set of coupled linear algebraic equations, which could be explicitely solved.

• 对有限链,Bethe Ansatz方程极复杂,注意到体系的量子群对称性,利用q-畸变Young算子,可将此哈密顿体系约化为一组耦合的线性代数方程,可明显解出。
