划转国有资本进社保:如何监管?

背景材料:划转部分国有资本充实社保基金,是基本养老保险制度改革和国有企业改革的重要组成部分,是保障和改善民生的重要举措。实际上,从2001年的\"国有股减持\"、2009年的\"国有股转持\"到此次的\"国有资本划转\",从设想、顶层设计到给出具体路线图和时间表,长期以来,让国资输血社保,党中央、国务院作

Magnetic properties of composites of Tb028Dy072Fe2 and polyvinylidene fluoride

Bi-ferroic particulate composites with Tb0.28Dy0.72Fe2 (Terfenol-D) particles randomly dispersed in ferroelectric polyvinylidene fluoride matrix prepared by a simple hot-pressing procedure were investigated. With increasing concentration of Terfenol-D, the magnetic susceptibility, saturation magnetization and initial permeability of the composites increases. The dependence of the effective magnetostriction on applied bias for the composites is similar to that for bulk Terfenol-D, but the effective magnetostriction strongly depends on the volume fraction of Terfenol-D. The observed behaviour of the composite is reasonably described by using effective medium theories

Spatial and temporal variations of vegetation surface albedo caused by snow in north China

<span class="hit">Albedo</span> is a key physics parameter <span class="hit">in</span> earth <span class="hit">surface</span>. It determines the ratio <span class="hit">of</span> solar energy absorbed <span class="hit">by</span> earth, and restricts the climate change between atmosphere and land <span class="hit">surface</span>. However, the uncertainty <span class="hit">of</span> <span class="hit">albedo</span> was not been considered sufficiently <span class="hit">in</span> most climate models, <span class="hit">snow</span> may be the most important source <span class="hit">of</span> this uncertainty. Season changes obviously <span class="hit">in</span> <span class="hit">north</span> <span class="hit">China</span>, which has different kinds <span class="hit">vegetation</span> types. Here we use the Moderate Resolution Imaging Spectroradiometer(MODIS) data to analysis the <span class="hit">spatial</span> and <span class="hit">temporal</span> effect <span class="hit">of</span> <span class="hit">albedo</span> change <span class="hit">caused</span> <span class="hit">by</span> <span class="hit">snow</span>. The result indicates that general distribution <span class="hit">of</span> <span class="hit">albedo</span> fallow the pattern <span class="hit">of</span> the <span class="hit">vegetation</span> cover type, have more heterogeneous under <span class="hit">snow</span> conditions. <span class="hit">Albedo</span> also have dramatic <span class="hit">temporal</span> various not only during the season change period, but also <span class="hit">in</span> the middle <span class="hit">of</span> winter
