很多人冲马桶都没有盖上盖子的习惯，殊不知这样做给了病毒传播的便利。扬州大学的研究发现，冲马桶时不合盖，升腾的水雾可达到头部高度，从而可能让人吸入水雾中的病毒。 Photo by Giorgio Trovato on Unsplash Flushing the toilet with the lid up creates a cloud of spray that can be breathed in and may spread infection, such as coronavirus, say researchers. 研究人员称，冲马桶时不盖上盖子，就会吸入马桶上方的水雾，从而可能感染和传播病毒，比如新冠病毒。 Chinese scientists calculate that flushing can propel a plume of spray up and out of the toilet bowl, reaching head height and beyond. 中国科学家估算，冲马桶会造成马桶中的水雾升腾到头部高度甚至更高。 Droplets can travel up to 3ft - or 91cm - from ground level, according to the computer model used by the scientists from Yangzhou University. 根据扬州大学的科学家运用的计算机模型，Shutting the lid would avoid this. 盖上马桶盖子则会避免这种传播。 The work is published in the journal Physics of Fluids. 该研究发表在期刊《流体物理学》上。 Coronavirus is spread through airborne droplets from coughs and sneezes, or objects that are contaminated with them. 新冠病毒通过咳嗽和打喷嚏散布到空气中的飞沫，或是被新冠病毒污染的物体来传播。 |
