摘　　要：基于符号计算系统Mathmatica,利用广田双线性方法研究了(3+1)维Boiti-Leon-Manna-Pempinelli方程和一个(3+1)维非线性发展方程的lump解.获得的lump解涉及8个自由参数,并且选取不同的参数值对三维图和等高线图进行序列分析.结果表明,当参数值接近于零时,对应的lump解趋于零.最后,给出了包含特定参数值的lump解的图.In this paper, by means of symbolic computation system Mathmatica, the lump solutions of the(3+1)-dimensional Boiti-Leon-Manna-Pempinelli equation and the(3+l)-dimensional nonlinear evolution equation are studied via Hirota bilinear method.The obtained lump solutions involve eight free parameters, and different parameter values are selected for sequence analysis of three-dimensional and contour maps.The results show that when the parameter value is close to zero, the corresponding lump solution tends to zero.Finally, we give a graph of the lump solution containing specific parameter values.
