摘要：We investigate the stability and instability for a generic non-conservative compressible two-fluid model in the present paper. Under the condition that the initial fraction densities are close to the constant equilibrium state in $H^3\cap\dot B^{s}_{1,\infty}$ and the initial velocities are small in $H^2\cap\dot B^{s}_{1,\infty}$, we establish the global existence and large time behavior of classical solutions by the delicate energy method if  $0\le s\le \frac{1}{2}$. On the other hand, we show that the steady-state is nonlinear unstable in the sense of Hadamard if $\frac{1}{2}<s<1$.
