化学实验失败体验:教育现象学的视角

近10年来，教育现象学在我国迅猛发展，得到愈来愈多的关注，教育现象学已逐渐形成一套较为成熟与可操作的研究方法与步骤。运用教育现象学研究方法对学生实验失败体验进行研究，得出根本主题：化学实验失败（包括实验意外）体验丰富，其增强或消减受多种因素（老师指导、同伴合作与竞争、自身、时间长短）的单一与相互影响。并从空间性、实体性、时间性、相关性等维度对根本主题的意义进行了论述。并与国际相关研究进行了比较，最后指出了该方法的适用范围和应用前景。     

Heavy quarkonia spectra and their decays in a relativistic quark model

Using the phenomenological relativistic harmonic model (RHM) for quarks, we have obtained the masses of S wave charmonium and bottomonium states. The full Hamiltonian used in the investigation has Lorentz scalar plus vector confinement potential, along with the confined one gluon exchange potential (COGEP). A good agreement with the experimental masses for the ground and the radially excited states is obtained both for the triplet and singlet S wave mesons. The decay properties of the ground state charmonium and bottomonium are investigated.     

Proton Spectroscopic Factors Deduced from Helium-3 Global Phenomenological and Microscopic Optical Model Potentials

Global phenomenological GDP08 and microscopic hefium-3 optical model potentials have been recently derived. We evaluate these two potential sets by comparing the elastic scattering data of 25 MeV 3He on 160, 180, 19F, 23Na, 24Mg, 25Mg, 26Mg, 27A1, 28Si, 30Si, 31p, 32S, 34S, 35Cl, 3761, and 39K isotopes. Using the deuteron angular distributions calculated with the distorted wave Born approximation model, we extract the ground-state proton spectroscopic factors from （3He, d） reactions on the same set of nuclei. The extracted proton spectroscopic factors are compared with the large-basis shell-model calculations.

Numerical Simulation of the Elastic Shrinkage Induced by Portevin-Le Chatelier Effect

A new one-dimensional phenomenological model based on the dynamic strain aging mechanism is developed. In order to account for the elastic shrinkage induced by the Portevin-Le Chatelier effect, elastic deformation is considered under the boundary conditions of the present model. The simulated results are found to be in good agreement with the experimental observations.     

Analysis of the X（1835） as a Baryonium State with the Bethe-Salpeter Equation

We take the X（1835） as a pseudoscalar baryonium state, and calculate the mass spectrum of the baryon-antibaryon bound states pp, ΣΣ, ΞΞ, and ΛΛ in the framework of the Bethe—Salpeter equation with a phenomenological potential. The numerical results indicate the pp, ΣΣ and ΞΞ bound states may exist, and the X（1835） can be tentatively identified as the pp bound state.     

Light meson spectrum and their leptonic decay widths in the frame work of constituent quark models

The phenomenological non-relativistic quark model has been employed to obtain the ground state masses of light vector mesons and their radially excited states and their decay widths.The full hamiltonian used in the investigation has kinetic energy,the confinement potential and the one-gluon-exchange potential.A good agreement is obtained with the experimental masses and their leptonic decay widths.
