摘　　要：借助于(q,r)导数引入了(q,r)变形熵的概念,并在此基础上使非广延统计力学公式化。进而用(q,r)变形熵讨论了在弱变形的情况下谐振子系统分布的一级关联。This paper introduces a (q,r)-deformed entropy by virtue of (q,r)-derivative and formulates the nonextensive statistical mechanics based on this (q,r)-deformed entropy.Then,applying this (q,r)-deformed entropy,we derive the first-order correction to the Planck distribution of harmonic oscillator system in weak deformation.
