In the study of moisture absorption and desorption in composites, Fick s law is often used to describe the diffusion process of water in the composites. 在研究复合材料层合板的吸湿和退湿过程中，常常采用菲克定理来描述水分在层合板中的扩散过程。
In this paper,Lou soil was amended with PAM at varied ratios of 0.1%,0.2% and 0.4%,and technique of phosphorus isotherm absorption and desorption was employed to study the effect of PAM on phosphorus retention and release in Lou soil. 本文采用向土壤(土娄土)中添加不同比例(0.
On the basis of process simulation and basic theoretical analysis, a new energy saving double-column process is proposed for FCC absorption and desorption system with " bi-directional mass transfer". 在流程模拟和基本原理分析的基础上,指出FCC装置吸收稳定系统吸收解吸过程存在双向传质,提出了一种新的改进型节能双塔流程。
A theoretical study of potential energy of solid surfaces and a deeply discussing of the influence of the adsorbed gases in the solid surfaces to the process of absorption and desorption were given. 从分子之间的作用力和分子之间相互作用的能量的角度对真空科学中表面吸附的位势理论进行了理论研究，并深入地探讨了固体表面吸附的气体分子层对气体的吸附与脱附的影响。
