摘　　要：德拜长度是描述等离子体中电荷的作用尺度的典型长度,是等离子体的重要参量。研究了非广延分布等离子体中的德拜长度,当非广延参数q→1时,非广延德拜长度回到经典统计下的结果,讨论了非广延参数对德拜长度的影响。The phenomenon of Debye shielding was considered within the framework of the Tsallis statistical mechanics.The Debye length is a typical length scale in the description of plasma.An analytical expression of the effective Debye length was derived.When q→1,the nonextensive Debye length reduces to the classic statistics of the results.The influence of nonextensive parameters on Debye length was discussed.

关 键 词：非广延 等离子体 德拜长度
