摘要
本文从方差分析的角度,判定趋势面的优劣,建立最优趋势面模型,并把该方法应用到分析大气SO_2浓度的分布规律中。在对武汉市汉口地区大气的研究中,发现影响城市大气中SO_2地面分布的主要趋势源有两个,城市居民最密集地区的大气SO_2浓度为0.06～0.08mg/m^3。
The present study by using an analysis of variance,first discriminated which trend-surface is best and then built the best trend-surface model. This method was employed in an analysis of distribution regularity of sulphur dioxide in air. Two main trend sources influencing air distribution near the ground were found in the research of the air of Hankou area in Wuhan city. The concentration of sulphur dioxide in the air of the most dense population area of the city is 0. 06-0. 08 mg/m3.
