Abstract A mechanism of the heavy quark dominance in orbital excitation is proposed this paper which testified to be reasonable for singly and doubly baryons. In relativistic model, an analysis Hamiltonian figures out that mode with lower energy levels always associated quark(s), splitting suppressed by quark(s). So, quarks dominate Furthermore, a physical understanding given semi-classical way. Accordingly, predicted mass spectra baryons confirm rationality mechanism. addition, interesting...

Magnetic resonance sounding (MRS) is a promising geophysical method for the direct detection and quantification of groundwater. However, two-dimensional MRS inversion usually seriously ill-posed because amount observational data far less than number subdivisions in area. To solve this problem, it necessary to reasonably mesh underground space impose proper constraints on model according available prior information. Influenced by gravity structure, distribution groundwater often has certain...
