By modulating the strength of spin splitting, we found that the spin polarization within an organic chain is weaker than that within a metal chain, but stronger than that within a semiconductor.

The valence band spin splitting for a superlattice composed of AlAs, Al y Ga 1- y As, Al x Ga 1- x As and GaAs is studied in this paper.

The effects of iso-scalar to tensor coupling on spin-orbit splittings are studied in the framework of the Relativistic Mean Field theory.

The calculations of the rate coefficients for dielectronic recombination (DR) along the (CuⅠ) isoelectronic sequence in the ground state Dy~(37+) through Zn-like inner-shell excited configurations were performed using the model of SOSA.

The calculations of the rate coefficients for dielectronic recombination (DR) along the NiI isoelectronic sequence in the ground state Gd 36+ through Cu like inner shell excited configurations were performed using the model of SOSA.

02keV ~ 10keV under the model of SOSA (spin-orbit-splitarray).

Based on the characteristics in the strength of coal seam under the action of the ground pressure, the impact coal cutting is achieved in the coal winning technique by using the impact cutting tool to impact, split and cut the coal on the coal wall.

To the cracks on the bottom of the slabs,the effect of water is just like the uniform forces assigned on the crack face which lead to the cracks to split.

Plain high strength concr ete and plain normal strength concrete,fiber high strength concrete and fiber no rmal strength concrete were tested respectively with split test and their capaci ty to resist propagation of.
