| 摘 要： | 平衡体系热力学推导涨落的前提是涨落必须很小，如果得到一个发散的结果说明这一涨落是不可靠的.对一些体系温度涨落的热力学结果，在温度趋于绝对零度时是发散的，这时必须用统计物理来处理.对这些体系进行统计物理处理的结果表明，涨落在温度趋于绝对零度时是趋于零的.

| Abstract: | The presupposition of deriving the fluctuation from equilibrium thermodynamics is that the fluctuation must be small, yet for some systems the derived temperature fluctuations are divergent as the temperature approaches 0K. For such fluctuations, the statistical physics has to be utilized to yield the correct results. Our results show that the fluctuations go to zero as the temperature approaches 0K. |
