查询词典 spectrum distribution

Statistical characteristics include Tectonic Density, Degree of Central Symmetry, Skewness Index, Degree of Tectonic Optimal Direction, Power Spectrum Density, Cubic Entropy and so on. The former four indexes are implemented in this paper; Structural characteristics show the characteristics of spatial distribution of geological bodies. In chapter four, a quantitative method for describing geological structure by using the structure "tree" is studied and implemented, including its formalized definition and the measurement of the similarity of different "trees".
