The study on daily variation characteristics of PM10 concentration based on the attribute partial order structure diagram

As an important tool for data analysis and knowledge processing, formal concept analysis has been applied to many fields. In this paper, we introduce a new visualization method of a concept lattice and the attribute partial order structure diagram (APOSD), we obtain the analysis method of the daily variation characteristics of PM
₁₀
concentration. Through in-depth analysis of the APOSD by granulating the PM
₁₀
concentration data, it is confirmed the effectiveness and rapidity of the proposed method, to grasp the law in perspective and to discover new relationship. To provide scientific basis for improving the environment.
