摘要： 根据Lindemann定律和乘积(αBT)为常数的近似条件，提出了一种计算高压下晶体熔点的方法，并对LiF，NaCl和Al三种晶体在不同压强下的熔化温度进行了计算.结果表明，计算得到的熔化曲线与实验数据吻合较好.

Abstract: According to the Lindemann′s law and the approximate condition that the quantity αBT is a constant above the Debye temperature, this paper proposed a method to calculate the melting temperature of crystals at high pressure,and calculated the melting temperatures at different pressure for three crystals (LiF, NaCl and Al). The results show that the agreement between the melting curves calculated and the experimental data is good.

Key words: high pressure, Lindemann′s law, equation of state, melting temperature, high pressure, Lindemann′s law, equation of state
