摘要：

The article mainly studies the isentropic approximation of the compressible Euler equations in Besov space B2,rs(RN), provided the initial entropy S similar to 0(x) changes closing a constant delta in the Besov spaces, which extends and improves the result in Sobolev space L2(RN) by Jia and Pan.
