【Abstract】 Recent advances in discrimination of nuclear explosions and earthquake are reviewed in this paper. The developing process from frequency spectrum ratios, magnitude ratios to synthetic probability method has been discussed. In particular, It is emphasized the importance of discrimination in nuclear explosion with small yield. By use of the quantum field theory and the phase transition theory in physics, the relation between the seismic wavelength and the wave momentum is analysed. At the same time, the possibility for generating soliton due to the actions of nonlinear and dispersion in crust during the seismic wave propagation is also discussed.更多还原
