similarity factor
2.We discussed the main characteristic parameters of seismic kinesiology and dynamics of mine engineering fracture zone, including relative amplitude, phase time of wave crest, similarity factor, principal frequency band energy, 3-D space time gradient and coherent coefficient et al., and puts forward the processing method of 3-D seismic characteristic parameters about denoise-smoothing, generalization, correlation analysis, characteristic transformation; and presents the method of pattern recognition of mine engineering fracture zone.
3.In the present study we used conventional CoMFA and introduced four routines of modified CoMFA, cross-validated R2-guided regional selection ( q2-GRS), all-orientation search (AOS), all-placement search (APS) and comparative molecular similarity indices analysis (CoMSIA) , to investigate a set of 18 pinusolide and its derivatives as a kind of newly discovered platelet activating factor (PAF) antagonist.
