Based on the expression of pressure at temperature T and in terms of the universal equation of state Debye model and the thermedynamic relations,a general expression for the cal-cutation of the linear thermal expansion coefficients of metals is obtained.

• 从温度T时的压强表达式出发，结合普适状态方程（UEOS）、Cebye模型和热力学关系式，给出了计算金属线性热膨胀系数的普遍公式。
