We extend Bespalov-Talanov (B-T) theory on small-scale self-focusing (SSSF) to include vector effect of a very narrow intense laser beam with application of the
A reverse condition of accretion flow and its constraints on black hole spin in the quasi-cycle are proposed. It is shown that the necessary condition for the q
The ceramic samples with nominal composition of La2/sCai/3Mn1-xFexO3 (0.01 ≤ x ≤ 0.20) were prepared by solid state reaction method. The effect of Fe doping o
A new method for quantitatively evaluating the alignment degree ofsintered Nd-FeB magnets by x-ray diffraction spectra has been proposed. It has been experiment
