研究了两类边界条件（孤子保持和孤子非保持）对自旋链和开自旋链的影响。适当的反射方程制定和相应的解决方案进行了分类。的对称性和Bethe anomaly方程推导出每种情况下。给出了与“孤子保持”情形相关的非对角反射矩阵的一般处理方法。还讨论了“孤立子非保持”边界条件与扭曲（超）杨吉安之间的联系。
Two types of boundary conditions (‘soliton preserving’ and ‘soliton non-preserving’) are investigated for the and open spin chains. The appropriate reflection equations are formulated and the corresponding solutions are classified. The symmetry and the Bethe ansatz equations are derived for each case. The general treatment for non-diagonal reflection matrices associated with the ‘soliton preserving’ case is worked out. The connection between the ‘soliton non-preserving’ boundary conditions and the twisted (super-) Yangians is also discussed.
