摘要
应用exp-函数法求得(2+1)维sine-Gordon方程的单孤子解、双孤子解、三孤子解,通过选取适当的参数,分别做出了单孤子解、双孤子解、三孤子解的函数图像,刻画了解的结构和性质.实践证明,应用exp-函数法研究非线性偏微分方程具有十分重要的作用和意义.
The single-soliton solution, the double-soliton solution and the three-soliton solution for the （2＋1）-dimensional sine-Gordon equation are obtained by using the exp-function method. By choosing the appropriate parameters, the singlesoliton solution, the double-soliton solution and the three-soliton solution are respectively obtained, and the structure and properties of the solutions are described. The results show that the application of exp-funetion method plays an important role and significance in the study of nonlinear partial differential equations.
