A simple analytic theory of thermodynamics at finite temperature for the spin-1/2 antiferromagnetic Heisenberg chain is proposed based on the picture of the par
The expression of the ground-state energy of an electron coupled simultaneously with a Coulomb potential and a longitudinal-optical phonon field in parabolic qu
The effects of the background ions on the selection of the discharge path in an air gap have been studied with two different methods. The lightning impulse air
Resistive transitions of the new superconductor MgB2 are carried out under magnetic fields from 0 to 8 T.It is found that the irreversibility field Hirr(T) and
Based on the spectrum measurement,we have investigated the single bubble sonoluminescence(SBSL)driven by a biharmonic ultrasound.The spectral temperature is sen
We investigate the orbit loss of alpha particles under helical magnetic perturbation in a tokamak. The results show that low-frequency andlow-mode number magnet
The charge transfer rate coefficients for reactions of Sc3+ with N2 and H2 have been measured at the meancollision energy of 4.2 Ev. The rate coefficients are d
