摘要：

A new scheme to perform the stability analysis based only on the knowledge of the equilibrium series is developed. A change of stability occurs only at the point where the eigenvalue of an allowed fluctuation mode changes its sign through zero. This means that the entropy is not necessarily required to be concave for a thermodynamic system to be stable under given circumstances.
