摘要
<正>More than 455 million people have been infected and 6.0 million people have died from the corona virus disease 2019(COVID-19) till March 12, 2022 (https://coronavirus.jhu.edu/map.html, accessed 2022/3/12). People may be infected with COVID-19 by inhaling the respiratory droplets containing the viruses or by touching their eyes and mouths after contacting the surface where droplets released by the patients via coughing or breathing might persist, e.g., the doorknobs and escalators in public places[1]. To get protected, people have begun to wear masks and apply hand sanitizers during their daily life. As a result, some massive productions and sales of these personal protective supplies have been induced by their growing global demand [2].
