摘　　要：用动力系统分支理论和微分方程数值算法研究了压缩弹性杆模型的Compacton解.在不同的参数条件下,利用Maple软件绘出了Compacton解的波形图.给出了精确的Compacton解的隐函数表达式.By using the bifurcation theory of dynamic system and the method of numerical simulation of differential equation and the compacton solutions of the model of compressible elastic rod have been studied. Under the different parametric conditions and by using Maple software, the graph of the compacton waves are shown. Some implicit - function expressions of the exact compacton solutions are given.
