中文摘要：
研究三维空间中带阻尼项的等熵可压缩欧拉方程组的初边值问题的球对称解的爆破.采用泛函方法,在几种关于初始速度的泛函足够大时,分别得到了经典解在某一时刻前必定爆破的结论.与无阻尼情形比较,阻尼的存在增加了经典解爆破的难度.
英文摘要：
In this paper we study the blowup of axis-symmetric solutions for the initial-boundary value problem of the compressible isentropic Euler equation in R3.We show by functional methods that classical solutions will blow up before a certain time under the assumption that the functional associated with the initial velocity is sufficiently large.Compared to the non-damping case,the damping increased the difficulty of the blowup of the classical solution.
