摘　　要：利用解析势能函数研究了FCC,HCP及BCC共19种金属的线膨胀系数、德拜温度和杨氏模量等之间的关联性,给出了金属的德拜温度和杨氏模量的解析计算式,其理论计算值与实验值符合较好.The correlations among linear expansion coefficient, Debye temperature and Young modulus of 19 kinds of FCC, HCP and BCC metals were studied by using the potential energy function. Then the analytical formulas for calculating Debye temperature and Young modulus of metals were given. The calculated values were consistent with the experimental data.
