The thermodynamics function such as isosteric heat of sorption of water has recently been studied from EMC isotherm of grains and food.
概述了谷物平衡水分测定的原理及数学模型分析,并归纳,发生纳滞后效应的可能理论、影响谷物吸着(包括吸附与解吸)等温线测定的因子,还重点介绍了近年发展起来的、利用平衡水分吸附/解吸数据分析谷物及食品的热动力学函数——水分吸着等热。
By these isotherms,the relationship between differential heat of absorption Q L,free energy change Δ[WTBX]G,entropy change TΔS and moisture content.
为了弄清楚热处理木材细胞壁中的水分吸着环境,即由半纤维素和木素组成的无定形区构造的变化,本研究通过对未处理及150,180,230℃处理云杉材在温度为20℃和50℃时的水分吸着等温线的测定,得到了吸着水的微分吸着热QL、微分吸着自由能ΔG及微分吸着熵TΔS与水分吸着量W、热处理温度之间的关系。
