二手烟包括“侧流烟”(烟草产品燃烧释放的烟)和“主流烟”(吸烟者呼出的烟)。
Secondhand smoke is the combination of "sidestream" smoke (the smoke given off by a burning tobacco product) and "mainstream" smoke (the smoke exhaled by a smoker).
二手烟不仅来自吸烟者呼出的烟气(我们称之为主流烟气),而且来自从烟尾、雪茄或者烟管中飘散出的烟气(我们称之为测流烟)。
Secondhand smoke comes from both the smoke that smokers exhale (called mainstream smoke) and the smoke floating from the end of the cigarette, cigar, or pipe (called sidestream smoke).
对吸烟和二手烟的健康危害,公众有着大量误解。主流社会认为吸烟是可接受的习惯,因此吸烟仍很广泛。
Numerous public misconceptions remain about the health hazards of smoking and secondhand smoke. Mainstream society considers smoking an accepted behavior and smoking remains popular.
