摘要
N2O是一种痕量气体,对大气化学和温室效应具有重要影响。N2O在大气中的浓度正日益增长,而且呈现出以3年为步长的振荡周期特点。N2O的释放源包括人为源和天然源,人为源是导致其增长的主要原因。N2O的汇主要在平流层,但N2O被破坏的同时也导致臭氧层的消耗。
N_2O is the most important trace gas, that greatly influences atmosphere chemistry and greenhouse effect. Concentration of N_2O in the atmosphere is increasing, and appear to have a quasi-triennial cycle in the data. The sources of N_2O include natural sources and anthropogenic sources. The latter is the main cause to result in the increase of N_2O. The sinks of N_2O are mainly in the stratosphere, but the destroy of N_2O also causes dissipation of ozone simultaneously.
