根据固体的弹性模量对温度的依赖性能了解高温下的热弹性性质,我们得到了弹性模量与等压体积膨胀存在精确的指数形式公式,并计算了和这两种物质在不同温度下的弹性常数.所有计算结果和实验之吻合很好.

Theremoelastu properties of non-cubic minerals at high temperature can be understood adequately by knowing the temperature dependences of their elastic constants.It has been found that there exists a precise relationship showing exponential dependence of their elastic constants on isobaric volume expansion for some typical non-cubic minerals such as Al2O3 and Mg2SiO4 at high temperatures.We have calculated the values of elastic constants at different temperatures for the noncubic minerals under study.The calculated values of elastic constants are found to show fairly good agreement with available experimental data.
