Based on the fundamental theory of wavelet analysis,this paper presents a kind of equivalent model concerning wavelet decomposition atomic time algorithm on the basis of analyzing wavelet decomposition atomic time algorithm.

The only way to improve the efficiency of the signal processing is to explore better and more efficient time-frequency atom decomposition methods.

Using time operator splitting technique and weighted essentially non-oscillatory(WENO) schemes to simulate detonation with detailed chemical reaction,a time operator splitting technique is employed to decouple hydra-dynamic transport and chemical reaction,and finite volume WENO scheme is constructed for the homogeneous Euler equations with complex equation of state.

Using time operator splitting technique and weighted essentially nonoscillatory(WENO) schemes to simulate detonation with detailed chemical reaction,we obtain its unique and regular detonation wave cellular structure.

In this paper,by means of numerical calculations,the squeezing effect of atomic operator in the binomial states field interacting with a two-level atom is discussed.
