中文摘要：

通过探测紫外后向散射获取臭氧总量目前已经成为臭氧总量探测的主要方法之一．本文以模拟计算为主要方法，从模式计算误差，反演算法误差和仪器误差三方面着手，对影响臭氧总量反演精度的各个参数进行分析研究，并对由其引起的臭氧总量反演误差进行定量计算，研究结果对臭氧总量反演精度的提高和实际观测资料的处理有着重要的指导意义．

英文摘要：

Now total atmospheric ozone amount derivation from the solar ultraviolet radiation backscattered from Earth measured by satellite has been one of the main methods to obtain total ozone amount data. Based on simulating calculation results, the paper studies and discusses the parameters which would influence the retrieval of total ozone amount arising from instrument errors and academic calculation errors, then quantificationally calculates the retrieval errors of total ozone amount induced by atmospheric radiative transfer model calculation errors, retrieval algorithm errors and instrument errors. The results obtained are very important for the precision improvement of total ozone amount retrieval and are directive for the disposal of the true datum obtained from FY-3A total ozone unit（FY-3A/TOU） in the future.
