摘要
讨论了非金属晶体的导热系数ｋ与压力ｐ和温度Ｔ的相互关系。从理论上导出了低压和低温下的两个实验拟合关系式，即ｋ＿Ｔ＝Ａ＋Ｂｐ和ｋ＿ｐ＝Ａ＿１＋Ｂ＿１／Ｔ，其中Ａ、Ｂ、Ａ＿１、Ｂ＿１为拟合常数。计算结果与实验结果符合得非常好。此外，还讨论了ｋ在高压、高温及冲击压缩下的响应。
The pressure (p) and temperature(T) dependences of thermal conductivity (k) fornonmetal crystals are discussed. The equations k_T=A+BP at low pressures and k_p= A_1+B_1 /T atlow temperatures that fitted from experimental data are developed in theory , where A , B , A_1 andB_1 are fitting constants and the subscripts T and p refer isothermal and isobaric,respectively. Thecalculated results are in good accord with the experimental result. The responses of k under highpressure-high temperature and shock compressions are discussed as well.
