摘要(Abstract):

应用热力学基本理论,建立中药饮片水分吸附与解吸附过程中的热力学参数及相关方程,分析中药饮片的水分吸附与解吸附特性。探讨微分吸附焓、微分吸附熵、积分吸附焓、积分吸附熵和吸附结合自由能等热力学参数的物理意义,为中药饮片的水分吸附与解吸附机制、最佳干燥工艺参数、贮存条件、包装方法等方面研究提供理论依据。
Based on the basic theory of thermodynamics, the thermodynamic parameters and related equations in the process of w ater adsorption and desorption of C hinese herbal decoction pieces w ere established,and their w ater absorption and desorption characteristics w ere analyzed. T he physical significance of the therm odynam ic param eters,such as differential adsorption enthalpy,differential adsorption entropy,integral adsorption enthalpy,integral adsorption entropy and the free energy of adsorption,w ere discussed in this paper to provide theoretical basis for the research on the w ater adsorption and desorption m echanism,optim um drying process param eters, storage conditions and packaging m ethods of C hinese herbal decoction pieces.
