We calculate some Wilson loop functionals in a static sphere-symmetrical diagonal metric field and a gravitational metric field established by a cosmic string.
The unified chaotic system contains the Lorenz and the Chen systems as two dual systems at the two extrcmes of its parameter spectrum and the Lii system as a sp
Using a detailed configuration accounting model with term structures treated by the unresolved transition array model, we have extensively investigated the opac
We investigated the magnetism of systems Lao.7-xGdxSro.3MnO3 (x = 0.00, 0.10, 0.15, 0.20, 0.30, 0.40, 0.50,0.60, 0.70) by M-T curves, M-H curves, and electron-s
By considering the vortex-like ion distribution, we know that the nonlinear dust acoustic wave can be described by the modified Korteweg-de Vries equation. If t
Pulsed molybdenum ion beams extracted from a metal vapour vacuum arc ion source at voltage of 25kV or 48kV were implanted into H13 steel with a high implantatio
A sinusoidal chirp structure is proposed to improve the performance of fibre gratings as dispersion compensators and multichannel filters. Nearly ideal refiecti
