我们建立了(A,0,C,D)型的Darboux特殊等温曲面与二阶偏微分方程的解之间的对应关系:u\Delta(u)-|\nabla(u)|^{2}+\Phi^{4}=s,s \in R.然后利用等温面的经典达布变换构造了该方程的B\“acklund变换,并证明了其解的叠加公式。作为应用,我们讨论了1,2-孤子解和相应的曲面。
We establish a correspondence between Darboux's special isothermic surfaces of type (A,0,C,D) and the solutions of the second order PDE : u\Delta(u)-|\nabla(u)|^{2}+\Phi^{4}=s, s \in R. We then use the classical Darboux transformation for isothermic surfaces to construct a B\"acklund transformation for this equation and prove a superposition formula for its solutions. As an application we discuss 1 and 2-soliton solutions and the corresponding surfaces.
