| 摘 要： | 在广义黑体辐射分布函数的基础上得到了非广延统计中爱因斯坦自发辐射系数Amk、受激发射系数Bmk和吸收系数Bkm的关系。结果表明，受激发射系数Bmk吸收系数Bkm之比不仅依赖于能∈k级∈m、频率vmk、温度T，还与非广延参数q有关。在q=1时，广义形式回到经典形式，爱因斯坦系数之比Bmk／Bkm=1

| Abstract: | Based on the nonextensive blac-body radition distribution function, The relations between Einstein＇s spontaneous emission coefficient Amk , stimulated emission coefficient Bkm and the absorption coefficient Bkm are obtained in nonextensive statistics. These results show that the ratio of the stimulated emission coefficient to the absorption coefficient depends on∈k,∈m,vmk T and the nonextensive q , in the limit q = 1 , the generalized ratio Einstein＇ s coefficient becomesBmk/Bkm=1 |
