摘要: 根据液体的自由体积理论导出了高压熔化的积分表达式。利用熔点处粒子的自由体积与其平均体积之比很小这一特性,给出了简化的自由体积高压熔化公式,简化公式具有与通常使用的高压Lindemann熔化公式完全相同的形式。初步探讨了Lindemann定律的物理内涵。

Abstract: An integral melting equation was derived according to free volume theory. Because free volume, Vf is much smaller than cell volume V (Vf/V0.005~0.01) at melting temperature, a simplified formula was obtained to be the same as Lindemann equation. The immanent physics of Lindemann law is discussed briefly.-
