摘　　要：为研究不同叠加佩戴方式下口罩关键性能的变化情况,给佩戴者提出合理化的佩戴建议,选择N95口罩(N95)、柳叶形口罩(L)、平面口罩(P)和布口罩(B),对日常生活中10种常见的叠加佩戴方式进行试验。对不同叠加佩戴方式的过滤效率、防护效果和呼吸阻力进行测试,结果表明,N95、L、P、B口罩叠加佩戴时比单独佩戴的颗粒物过滤效率提高0.6%~82.37%,呼吸阻力增加39.2%~67.7%,而防护效果不一定提高。根据试验数据进行分析,N95口罩单独佩戴即可,不建议N95口罩与其他口罩进行叠加佩戴和同时佩戴两层N95口罩,不建议两个布口罩叠加佩戴。柳叶形口罩、平面口罩、布口罩可以相互叠加佩戴。In order to study the key performance changes of the mask under different wearing method and provide reasonable wearing suggestions,N95 masks(N95),willow-shaped masks(L),flat masks(P),and cloth masks(B)are selected for the experiments,and 10 common daily life superimposed wearing methods are carried out.Filtration efficiency,protective effect and breathing resistance of different wearing method are tested.The results show that compared with wearing mask alone,when N95,L,P and B masks are superimposed,the filtration efficiency is increased by 0.6%~82.37% and the breathing resistance is increased by 39.2%~67.7%,respectively,but the protective effect may not necessarily improve.According to the experimental data,N95 masks can be worn alone,it is not recommended to wear N95 masks superimposed with other masks or wear two layers of N95 masks,and it is not recommended to wear two cloth masks.Willow-shaped masks,flat masks,cloth masks can be worn on top of each other.
