制度建设是建立健全惩治和预防腐败体系的保证,不仅教育、监督本身要靠制度来规范,而且教育、监督的实施也要用制度来保障。从某种意义上讲,惩治和预防腐败体系就是一个制度体系,是一个由整体制度和局部制度、综合制度和配套制度相互结合、相互衔接、相辅相成的严密的制度反腐体系。 相似文献

结合CFG桩复合地基研究状况,利用ANSYS有限元程序,以数值分析的方法建立了CFG桩复合地基的整体弹塑性模型,分析了灰土褥垫层粘聚力和内摩擦角两个因素的变化对复合地基工作性能所产生的影响,得出:桩身应力沿深度变化的一个重要特征是其最大应力点不在桩顶,而是在桩顶下的某一深度处;随着灰土褥垫层粘聚力、内摩擦角、变形模量的增加,CFG桩复合地基的桩顶沉降量、桩顶应力值以及桩土应力比均增加,桩顶刺入量减小。 相似文献

Using a microcircuit fabricated on a diamond anvil cell, we have measured
in-situ conductivity of HgSe under high pressures, and investigated the
temperature dependence of conductivity under several different pressures. The result
shows that HgSe has a pressure-induced transition sequence from a semimetal
to a semiconductor to a metal, similar to that in HgTe. Several
discontinuous changes in conductivity are observed at around 1.5, 17, 29
and 49GPa, corresponding to the phase transitions from zinc-blende to
cinnabar to rocksalt to orthorhombic to an unknown structure, respectively.
In comparison with HgTe, it is speculated that the unknown structure may be
a distorted CsCl structure. For the cinnabar-HgSe, the energy gap as a
function of pressure is obtained according to the temperature dependence of
conductivity. The plot of the temperature dependence of conductivity
indicates that the unknown structure of HgSe has an electrical property of a
conductor. 相似文献
