| 摘要: |
| 本文从热膨胀系数a、比热 Cv 及体积弹性模量k所满足的热力学关系出发，提出了一种简单实用的递推方法计算热膨胀系数，用此方法可以相当准确地计算固体热膨胀系数作为温度函数的整个曲线。文中以三种碱卤晶体为例计算了室温以下的热膨胀系数，与实验结果符合得非常好。 |

| Abstract: |
| From the thermodynamic relationship among the thermal expansion coefficient α，specific heat Cv，and volume elastic modulusk，We proposed a simple practical recursion method to calculate the thermal expansion coefficient. The coefficient of thermal expansion of solid，as the function of temperature，can be determined very accurately by this method. As an example We have calculated the thermal expansion coefficient of three alkali halide crystals below the room temperature，the results are in sound agreement with the experiments. |
