This paper discusses the potential for enhancing the capabilities of the European FEL in the soft X-ray regime. A high longitudinal coherence will be the key to such performance upgrade. In order to r...
We construct a novel approach, based on thermodynamic geometry, to characterize first-order phase transitions from a microscopic perspective,through the scalar curvature in the equilibrium thermodynam...
The line shape of the open-charm radiative and pionic decays of Y(4274) as a molecular charmonium 。
The curvature which characterizes the QCD phase transition at finite temperature and small values of the chemical potential is accessible to lattice simulations. The results for this quantity which ha...
Based on the principles of transmission line and the output signal of GEM detector, a full simulation model of delay-line circuit has been described in this paper. The consistency of simulation result...
We study the positive-operator-valued measures on the projective real line covariant with respect to the projective group, assuming that the energy is a positive operator. This problem is similar to t...
期刊信息 篇名 On -line Measurement of Mass COncentration and Particle Size in Emission Using Light Scattering Technique 语种 英文 撰写或编译 作者 王乃宁,徐贯东 第一作者单位 刊物名称 C.P.Celata ed .Two -Phase 页面 1995,Vol.2,P.695-701 出...
A vortex line, shaped by a zigzag of pinning centers, is described here through a three-dimensional unit cell containing two pinning centers positioned symmetrically with respect to its center. The un...
Energetic electrons are unique in their capability to fully assess magnetic-fieldline topology and thus they should be able to clearly delineate regions of open and closed magnetic field lines in the ...
Measurements of the 19F NMR linewidth D n and spin-lattice relaxation rate 1/T1 have been performed in an oriented powder sample of fluorinated YBa2Cu4O8 at temperatures 4 < T < 300 K and static magne...
