First, the paper puts forward a smoke-puff trajectory model in which topography, deposition, chemical elimination and reflex effects within the mixture layer have been taken into consideration.

在模式中考虑了地形、沉积、化学衰减和混合层顶多次反射等影响因素的作用。

While these chemicals are attached to the cigarette smoke of tiny particles reach the alveoli, where deposition, mutually reinforcing, the result has greatly enhanced the carcinogenic effects.

这些毒物附在香烟烟雾的微小颗粒上，到达肺泡，并在那里沉积，彼此强化，结果又大大加强了致癌作用。
