基于在越来越多的物理系统中观察到的Q指数分布,可以利用可追溯到热力学第一定律和第二热力学定律的变分关系来导出这种异常分布的不确定度。本文所得的不确定度可视为具有可观测Q指数分布的反常物理系统的熵形式。当非扩展参数趋于1时,这个熵将趋于Boltzmann-Gibbs熵。很重要的一点是要发现,这种熵形式总是凹的,并且系统的熵是可最大化的。
Based on the q-exponential distribution which has been observed in more and more physical systems, the uncertainty measure of such an abnormal distribution can be derived by employing a variational relationship which can be traced from the first and second thermodynamic laws. The uncertainty measure obtained here can be considered as the entropic form for the abnormal physical systems having observable q-exponential distribution. This entropy will tend to the Boltzmann-Gibbs entropy when the nonextensive parameter tends to unity. It is very important to find that this entropic form is always concave and the systemic entropy is maximizable.
