Abstract:
With models deduced from plasma systems, some phenomena in nonlinear wave systems are studied, such as solitons, gap solitary waves, bifurcations and transition to turbulence. The mechanism of bifurcations and control of chaos are also explored.

Abstract:
The Schrdinger equation of hydrogen like atoms in a strong electric field is solved by the numerical method instead of perturbation. The resonance ionization of hydrogen atom ground state is computed and comparing with exact result and Breit Wigner parametrisation is useful.

Abstract:
By using the characteristic X ray sources and the Si( Li) detector system, the X ray mass attenuation coefficients for Si,Fe,Cu,Y,In,Sn and SiH 4 have been systematically measured in the energy range of 1.486~29.109 keV. The accuracy of experimental data has been reduced to ±1% .

Abstract:
Multicomponent ion beam enhanced deposition was used to synthesize (TiCr)N films. The films were characterized by AES,TEM and XRD methods. The electrochemical property and mechanics property of the films were measured. The experimental results show that the multicomponent ion beam enhanced deposition has stronger potential of new material development than physical vapour deposition.
