用超声波脉冲回波技术测定了单晶镉在300° ~ 575°K温度范围内的绝热弹性常数。在300°K下获得的值为C11 = 11.45、C33 = 5.085、C66 = 3.750、C44 = 1.985和C13 = 3.99，单位为1011 dyn/cm 2。的线性压缩，Gruneisen参数，和晶格的贡献，比热的温度依赖性已计算使用本研究中获得的弹性常数和其他必要的热数据在文献中。
The adiabatic elastic constants of single‐crystal cadmium have been determined by means of the ultrasonic pulse‐echo technique over the temperature interval from 300° to 575°K. The values obtained at 300°K are C11 = 11.45, C33 = 5.085, C66 = 3.750, C44 = 1.985, and C13 = 3.99 in units of 1011 dyn/cm2. The temperature dependences of the linear compressibilities, the Gruneisen parameter, and the lattice contribution to the specific heat have been calculated using the elastic constants obtained in the present study and other necessary thermal data available in the literature.
