In this paper,the author analysed Holmes' Duffing Equationd2x/dt2+δ(x2 + ax + c)dx/dt- ax +βx3 = 0and Its general form d2x/dt2+δf(x) dx/dt- ax +βx3 = 0 with Melikov Function method ,giving the conditims which stable on unstable limited circles are bifurcated from the homoclinic Oribits
With the theory of IBA2, the best Hamiltonian parameters of nuclcj 154Sm, 156Gd, 158Gd and 158Dy has been found from SU(3) limited ones, through comparing the theoretical and experimental value of excited energies and B(E2);
Thus,the Limited permissible concentration of these salts have been determined and the results showed that the limited. permissible concentra- tions of NaCl,Na_2SO_4 and CaCl_2 were 2.5×10~4 mg/l,6×10~4 mg/l and 4.5×10~4 mg/l respectively,whi- ch depend on several environmental factors.
Frequency-Domain Bounds for Nonnegative, Unsharply Band-Limited Functions
In this paper we give a further investigation of the method introduced by the author in [1, Frequency-domain bounds for nonnegative unsharply band-limited functions] for proving bounds for functions with nonnegative Fourier transforms.
Finite energy band-limited functions are reconstructed iteratively
