@IslandPirates77 @ChrisACole @elaine_hali @J_D_Klein @HalCranmer There is a lot of language in that paragraph that is just not applicable to community masking, such as that air "can pass through gaps" (how much air, and how much doesn't pass through gaps?). Or "can't be relied upon" (that's not the goal, the goal is risk *reduction*).
@IslandPirates77@ChrisACole@elaine_hali@J_D_Klein@HalCranmer该段中有很多语言不适用于社区掩蔽，比如空气“可以穿过缝隙”（有多少空气，有多少不穿过缝隙？）。或者“不可依赖”（这不是目标，目标是降低风险*）。
