摘要：

Ramshaw [Phys. Lett. A 198 (1995) 119] has recently shown that if one considers the generalized entropy S-q, equivalent to k(1 - Sigma(i)P(i)(q))/(q - 1) (q epsilon R; q = 1 corresponds to standard thermostatistics) and the standard internal energy UI Sigma(i)p(i) epsilon(i), then thermodynamic stability of the system is not guaranteed for all values of q. We show here that the (physically desirable) thermodynamic stability is restored if, instead of U-1, one uses the (consistently) generalized internal energy U-q equivalent to Sigma(i)P(i)(q) epsilon(i).
