中文摘要：

是的空柱体的光线的表面上的相同应用起始的压力的影响与第一力量低亚硫酸钠橡皮材料创作组成的模型被调查。这个问题的基本方程基于有橡皮的三维的线性化的理论的使用的同类的身体模型在开始强调的身体(TLTEWISB ) 挥动的 piecewise 的框架被建立。与以前建议的方法，这个问题然后数字地被解决。而且，有不同起始的压力的最低顺序模式的分散组速度也被学习。起始的压力和几何学参数愿望在相反的趋势在在阶段速度和波浪数字之间的散关系导致不同的度的可观的变化，这能被结束(在起始的压力积极、在厚度否定) 。

英文摘要：

Influence of identical applied initial pressures on the radial surfaces of a hollow cylinder which is compose of materials with first power hypo-elastic constitutive model was investigated.The basic equations of the problem were built up based on the framework of piecewise homogeneous body model with the use of three-dimensional linearized theory of elastic waves in initially stressed bodies（TLTEWISB）.With the method proposed previously,this problem was then solved numerically.Moreover,the dispersion group velocity of the lowest order mode with different initial pressures was also studied.It can be concluded that the initial pressure and the geometry parameters will induce considerable changes of different degrees in dispersive relation between phase velocity and wave number in opposite trend（positive in initial pressure and negative in thickness）.
