Abstract
The dynamic research status of three processes in chemical protection technology, namely, adsorption of steam by activated carbon, permeation of solvent by polymer film and filtering aerosol by cigarette paper were studied in this paper. The advantages and disadvantages of each model were analyzed, and the dynamic behaviors of the three processes were fully understood, which can effectively guide the research and development of chemical defense equipment and chemical defense of troops. It provides a reference for the study of the dynamic theory of the three processes.
