摘要
分析了现有温度概念之不足 ,从温度的解析表示式和玻尔兹曼关系出发 ,揭示了温度的微观本质 ,负温度存在的条件 ,负温度系统中正、负温度能区的本质区别 .最后对难平衡态系统中温度概念给出了严格定义 .
The inaclequacy for the conception of temperature is analysed.From the analgtic expression of temperature and the Boltymann's entropq formula,the micro essentiality of temperature,the condition for it exists as the negative temperature and the essential distinction of positive and negative energy region has been revealed.Finally,the nation of temperature in noneguilibrium has been defined in rigorous.
