The analysis indicates that temperature change can fall into three successive phases (temperature rising fast, temperature stabilization and temperature rising slowly); internal pressure is composed of vapor pressure and air pressure.

分析表明：板坯内部的温度变化分为3个阶段，即快速升温阶段、温度稳定阶段和后期的慢速升温阶段；内部气压由水蒸气分压和空气分压组成。
