Based on high resolution and high signal-to-noise ratio spectra, we determine the chemical abundance of nearby star HD131023 by using differential anlysis. Abun
Measurements of the total reaction cross section for 12-16C, 14-17N and 16-18 O on carbon target at intermediate energies were performed on RIBLL of HIRFL. A la
As a statistical model of black hole entropy, the brick-wall method based on the thermal equilibrium in a large scale cannot be applied to the cases out of equi
Low noise image amplification owing to contradirectional two-wave mixing (CTWM) is proposed and demonstrafed in Rh-doped BaTiOa crystal. Comparing with the conv
