The changes of total water content and free water content in burley tobacco leaf during the curing process in different humidity treatments controlled under both the artificial and natural conditions were studied respectively.

研究了自然条件和人工调控条件下,不同湿度处理的晾房中白肋烟叶片晾制期间总水含量和自由水含量的变化趋势,以探讨人工调控的条件下白肋烟晾制的合适湿度。

Definition,calculation and application of total water potential;

总水势概念的定义、计算及应用条件

In light of the fundamental principle in physics,this paper analyzes the total water potential concept built on energy viewpoint, and concludes that total water potential contains two energy forms: mechanical energy and thermal energy,which are the driving forces for water transfer and thermal dynamic processes.

依据物理学基本原理,分析了以能量观点为基础的总水势,得出其包括机械能和热能两种能量形式,这两种能量形式分别是水分机械运动和热运动的驱动力。
