【Abstract】 The blowup of the radial symmetric regular solutions for the N-dim compressible Euler equations is studied,while the initial flow is vacuum outside a ball.Under some assumptions,it is shown that the nontrivial classical solutions（ρ,V）blowup on or before the finite time T=2∫R₂0φ²（r）φ′（r）drH₀^-1.更多还原
