【摘要】 从Singh等人提出的关于固体的热膨胀系数与等温体积弹性模量的关系式出发,利用Anderson-Grüneisen参量的定义,得出等温体积弹性模量和热膨胀系数与温度间关系的表达式,再根据相关定义进一步得出体积热膨胀与温度间的方程式,并将得到的关系式应用至碱卤晶体NaCl和KCl,结果表明理论值与实验值符合得很好.更多还原

【Abstract】 Three relationships are obtained for determining isothermal bulk modulus,thermal expansivity and volume thermal expansion with temperature at 1 bar pressure for NaCl and KCl up or close to the melting temperatures.The results obtained from the relationships agree with the data on experimental studies for the temperature dependence of isothermal bulk modulus,thermal expansivity and volume thermal expansion.更多还原
