@sameo416 The well-mixed assumption has something going for it in a crowded environment. Increased exposure to one person due to non-uniform mixing almost equals reduced exposure to another (unless high/low risk areas are non-occupied, likely true to some extent, not entirely)
@sameo416在拥挤的环境中，混合良好的假设有其适用性。由于不均匀混合而增加对一个人的暴露几乎等于减少对另一个人的暴露（除非高/低风险区域没有被占用，在某种程度上可能是真的，而不是完全）
