This paper gives the conditions of existence of echo wave and the accurate expression of the relative period in the coupled Oregonators and finds that in this system there are two types of echo waves,one of which satisfies the pretty relations x\-1(t)+x\-2(t)=2u\++,z\-1(t)+z\-2(t)=2u\++ (where u\++ is a component of the homogeneous positive steady state of the system).

Divided energy of the double momentum coupling harmonic oscillator;

The energy splitting of the coupling harmonic oscillator in non-commutative spaces are discussed.

Exact solution for non-identical n modes coupled harmonic oscillators;

For the coupled harmonic oscillators,the energy spectrum of system relates with the coupling items and exists a minimum value,when(λp(0)/ωj(0))1 and(gi(0)/ωj(0))1,λp(0) and gi(0) are the anharmonic parameter,ωj(0) is the frequency of the harmonic oscillators,where i,j=a,b;p=1,2),the analytic equation is gained.
