@ems_jn Mannequins are less conducive to transmission. They don't turn their heads toward another passenger. They don't circulate around the cabin or use rest rooms. They don't take their masks off to eat or drink.
Reality is WORSE than what a mannequin study would suggest, not better.
@ems_jn人体模型不利于传播。他们不会把头转向另一位乘客。他们不在机舱内走动或使用洗手间。他们不摘下口罩吃饭或喝酒。
现实比人体模型研究所显示的更糟，而不是更好。
