摘要
从热膨胀系数和Anderson-Grüneisen参数的定义式出发,导出了弹性模量与等压体积膨胀随温度变化指数关系式.以MgO和CaO为例进行了数据处理和分析.结果表明理论预测值与实验结果吻合的很好.
Using the thermal expansion coefficient (αT) and the Anderson-Grüneisen parameter (δT) definition expression,we obtained a relationship for the volume dependence of the thermal expansion and the bulk modulus (BT).We have calculated the thermal expansion and the bulk modulus with this relationship for MgO and CaO at high temperature under study.The calculated values of BT and αT are found to show fairly in good agreement with available experimental data.
