【摘要】 从玻耳兹曼发布律出发，对处于负温度状态（即实现粒子数反转）的三能级激光工作物质系统的热力学温度进行了讨论，指出在负温度状态下，粒子系统的热力学温度仍可以大于零，证明了负温度状态并不等同于热力学温度Ｔ＜０的状态。更多还原

【Abstract】 Based on boltzmann distribution law,thermodynamic scale of temperature is discussed of three level laser working matter system in negative temperature state,realized population inversion.It is pointed out that thermodynamic scale of temperature of particle system may be still more than zero in negative temperature state,thus it is proved that negative temperature state cannot be equated with the state of thermodynamic scale of temperature T <0。更多还原
