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測(cè)定的原理及數(shù)學(xué)模型分析,并歸納,發(fā)生納滯后效應(yīng)的可能理論、影響谷物吸著(包括吸附與解吸)等溫線測(cè)定的因子,還重點(diǎn)介紹了近年發(fā)展起來(lái)的、利用平衡水分吸附/解吸數(shù)據(jù)分析谷物及食品的熱動(dòng)力學(xué)函數(shù)——水分吸著等熱。
By these isotherms,the relationship between differential heat of absorption Q L,free energy change Δ[WTBX]G,entropy change TΔS and moisture content.
為了弄清楚熱處理木材細(xì)胞壁中的水分吸著環(huán)境,即由半纖維素和木素組成的無(wú)定形區(qū)構(gòu)造的變化,本研究通過(guò)對(duì)未處理及150,180,230℃處理云杉材在溫度為20℃和50℃時(shí)的水分吸著等溫線的測(cè)定,得到了吸著水的微分吸著熱QL、微分吸著自由能ΔG及微分吸著熵TΔS與水分吸著量W、熱處理溫度之間的關(guān)系。
