转型期乡镇集体企业模糊产权的根源与明晰途径

明晰的产权意味着财产所有者对其财产的各个方面具有完全的控制权，模糊产权实际上是最终控制权模糊性．我国的乡镇集体企业是产权模糊的典型。从政企关系、市场体系、经营者的激励等方面可探明转型期乡镇企业模糊产权的形成原因．转型期政府与企业的关系决定了模糊产权的存在是社会强制机制作用的结果，转型期不完善的市场体系是导致模糊产权形成的环境因素，企业经营者的控制权激励是模糊产权得以延续的制度根源．

Studies on the Crystallization Properties and Morphology Structure of the Cationic Dyeable Polypropylene Fibers

The crystallization properties and morphology structure of the cationic dyeable polypropylene fibers which were produced by the blending spinning method were studied by making use of X-ray and scanning electron microscopy (SEM). It comes to the conclusions that the larger the crystallite size in the fibers is , the better the dycable properties of the fibers are and there is a little compatibility between the dyeable agent and polypropylene resin. And the dye-uptake of the fibers may be up to 90% because the dyeable agent can uniformly be scattered in polypropylene.

Structural and thermodynamic properties of AlB2 compound

We employ a first-principles plane wave method with the relativistic analytic pseudopotential of Hartwigsen, Goedecker and Hutter (HGH) scheme in the frame of DFT to calculate the equilibrium lattice parameters and the thermodynamic properties of AlB₂ compound with hcp structure. The obtained lattice parameters are in good agreement with the available experimental data and those calculated by others. Through the quasi-harmonic Debye model, obtained successfully are the dependences of the normalized lattice parameters a/a₀ and c/c₀ on pressure P, the normalized primitive cell volume V/V₀ on pressure P, the variation of the thermal expansion α with pressure P and temperature T, as well as the Debye temperature \Theta_D and the heat capacity C_V on pressure P and temperature T.
