本文在文献[4]的基础上,讨论了广义sinh-Gordon体系的Dressing对称性及其可定域化的条件。On the basis of the study in Ref [4],we construct the dressing transformations of the fundamental variables and show the dressing symmetry of the constrained system (extended sinh -Gordon equations). Finally, we discuss the ultralocalizable-criterion of an arbitrary 2D integrable model.
