摘要: 从克拉珀龙方程出发讨论了金属的升华能随温度和压强的变化规律.研究表明,升华能随温度或压强的增大而近似线性地减小.

关键词: 升华能, 温度, 压强

Abstract: The vatiations of the sublimation energy with temperature and pressure are discussed according tothe Clapeyron equation. It is indicated that the sublimation energy decreases linearly with increase of tempera-ture and pressure.

Key words: sublimation energy, temperature, pressure
