美国麻省理工学院的最新研究发现,一个中等大小的喷嚏只需几分钟就能通过飞沫污染整个房间。研究中,麻省理工学院疾病传播实验室的研究员录制了一组室内视频。视频中,两个健康人士在几天里连续打了约50个喷嚏。该团队也首次发现飞沫是如何飞散并污染角落的。保奥巴表示,从物理学角度看,飞沫不都是整齐形成分布于口腔出口,相反,打喷嚏时,飞沫从肺部喷出,并经历了一个复 A recent study by the Massachusetts Institute of Technology found that a moderate sneeze pollutes the entire room with droplets of paint in minutes. In the study, researchers at MIT’s Disease Transmission Laboratory recorded a series of in-room videos. In the video, two healthy people made about 50 consecutive sneezes in a few days. For the first time, the team also found how the splash flew and polluted the corner. Paul Oba said that from a physical point of view, the droplets are not neatly distributed in the mouth of the oral distribution, on the contrary, when sneezing, the droplets spilled from the lungs, and experienced a complex
