查询词典 stable distribution

The richness center of the Theaceae plant species under study is located in the mountainous area of north Guaugdong (22.5°N, and 112~115°E). These plants species exhibited significant longitudinal difference (P=0.0012), and latitudinal variation (P=0.0049). Canonical Correspondence Analysis showed the distribution of plant species could be explained by caloric factors and moisture factors, and MAMI (mean annual minimum temperature) was the key factor determining the distribution pattern of Theaceae plant species richness in the study area.

In view of crosswell and 3D VSP layout, we use high resolution Radon transform based on Cauchy distribution to perform Radon transform for hole data. In this process, we study discrete dip overlay operator, improve damping factor that affects Radon energy convergence in order to let Radon energy converge, 6 resolve leggy in Radon data, and decouple smoothing effect among each energy group, we use Cauchy distribution to regularize data, let energy focus on one point, and improve Radon resolution. All these work well in wavefield separation. Finally, by inversion results and model trial, we verify the feasibility and stability of this method.
