研究了可压缩Navier-Stokes方程组球对称弱解的大时间行为.假设压强p（（?））=（?）γ,绝热指数γ>1,外力是球对称的.证明了假如外力满足一定的正则性及某种结构性条件,则当时间趋于无穷大时,密度将趋于其对应的静止问题的唯一解.

The authors consider the large time behavior of spherically symmetric weak solutions to compressible Navier-Stokes equations. It is assumed that P（Q = Qγ, γ〉 1 and the volume force is spherically symmetric. It is shown that for time tending to infinity, the density approaches the unique solution to the stationary problem, if the force satisfies certain ...
