关联维数在工业“三废”综合利用中的应用

The calculation method of fractal characteristic parameter-G-P (Grassberger-Procaccia) calculation method of the correction dimension is studied. Fracture feature analysis was applied to the ”three wastes” of products output data from 1986 to 2005 year in Hunan Province using the basic principle of correction dimensions, and m dimensional phase space was then constructed. The results indicated that the dynamic system had a relatively steady correlation dimension (2.98) after the embedd dimension came to be 7, which suggested that at lease three factors affects the dynamic changes of datas sequence, and the effective freedom was 7. The reaserch provides considerable references for establishing predictable model for it.
