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。
NF3 has a relatively short atmospheric lifetime (740 years) and dissociates more readily than C2F6 and CF4. HF ultimately diffuses down to the troposphere where it is removed by wet deposition.
NF3具有相对短的大气寿命（740年），比C2F6和CF4。更容易分解。HF最终扩散到大气中，在大气中它通过湿沉积被除去。
This was observed by diamond deposition on iron substrates where, due to the high vapor pressure of iron, ballas is formed at methane concentrations lower than 0.4%.
这一点是在铁基体上沉积金刚石时发现的。这时，由于铁的蒸汽压力很高，在甲烷浓度低于0.4%时可形成半刚石。
Soil erosion can result in land degradation and sediment deposition of a river, where soil erosion is connected with some natural factors and human activities.
土壤侵蚀是引起土地退化和河流泥沙淤积的根源，其产生与各种自然因素和人类活动存在一定关系。
