溧阳学宫遗址发现《平定青海告成太学碑》

《平定青海告成太学碑》是清初四大平定御碑之一,其内容为:追述清圣祖仁皇帝康熙为统一多民族国家下诏征讨朔漠的杰出贡献;次述青海之战中抚远大将军年羹尧等人的平叛战绩;后述战争胜利后举行的献俘仪式。     

祝允明诗文集版本考辨

一些史志目录录祝允明有《祝氏集略》三十卷,《怀星堂集》三十卷。本考查了目前所见此二集的内容及版本,发现二集实为一书,都应称为《祝氏集略》。而《枝山集》虽为历来的史志目录所忽略,但其本身确有相当的版本献价值。     

SEISMIC BEHAVIOUR OF PERIMETER AND SPATIAL STEEL FRAMES

The present study deals with the seismic performance of partial perimeter and spatial moment resisting frames (MRFs) for low-to-medium rise buildings. It seeks to establish perimeter configuration systems and hence the lack of redundancy can detrimentally affect the seismic response of framed buildings. The paper tackles this key issue by com-paring the performance of a set of perimeter and spatial MRFs, which were “consistently designed”. The starting point is the set of low-(three-storey) and medium-rise (nine-storey) perimeter frames designed within the SAC Steel Project for the Los Angeles, Seattle and Boston seismic zones. Extensive design analyses (static and multi-modal) of the perimeter frame buildings and consistent design of spatial frame systems, as an alternative to the perimeter configuration, were conducted within this analytical study. The objectives of the consistent design are two-fold, i.e. obtaining fundamental periods similar to those of the perimeter frames, i.e. same lateral stiffness under design horizon-tal loads, and supplying similar yield strength. The seismic behaviour of perimeter and spatial configuration structures was evaluated by means of push-over non-linear static analyses and inelastic dynamic analyses (non linear time histories). Comparisons be-tween analysis results were developed in a well defined framework since a clear scheme to define and evaluate relevant limit states is suggested. The failure modes, either local or global, were computed and correlated to design choices, particularly those concerning the strength requirements (column overstrength factors) and stiffness (elastic stability indexes). The inelastic response exhibited by the sample MRFs under severe ground motions was assessed in a detailed fashion. Conclusions are drawn in terms of local and global performance, namely global and inter-storey drifts, beam and column plas-tic rotations, hysteretic energy. The finding is that the seismic response of perimeter and spatial MRFs is fairly similar. Therefore, an equivalent behaviour between the two configurations can be obtained if the design is “consistent”.     

从“北方谈话”到“‘三中全会’主题报告”——邓小平与中国改革开放决策的酝酿

从1978年9月访朝归来到12月举行党的十一届三中全会,从"北方谈话"到"‘三中全会’主题报告",邓小平不仅明确提出了改革开放的时代课题,而且多方面地阐明了为什么要实行改革开放、要在哪些方面改革开放和如何实行改革开放等重大问题,实际完成了中国改革开放决策的酝酿,为"三中全会"最终作出实行改革开放的伟大决策,做好了充分的思想理论准备。回顾我国改革开放决策的酝酿过程,重温邓小平当时关于改革开放的论述,对在新的历史起点上全面深化改革开放具有多方面的意义。     

LEAD ISOTOPIC EVIDENCE FOR A MIXED PROVENANCE FOR ROMAN WATER PIPES FROM POMPEII*

Lead isotope analysis has been applied to the investigation of some Roman objects found in the town of Pompeii, consisting mostly of fistulae from the Augustan water supply system. The results of the analyses have produced ratios between 18.10 and 18.66 for ²⁰⁶Pb/²⁰⁴Pb, between 15.63 and 15.72 for ²⁰⁷Pb/²⁰⁴Pb and between 38.21 and 38.98 for ²⁰⁸Pb/²⁰⁴Pb. These data point to a fairly complex origin for the lead artefacts, probably involving several successive meltings and recyclings of a rather heterogeneous lead supply. The spread of lead isotope ratios can only be reconciled with a multiplicity of end‐members, at least three, but very probably more. There is one certain Sardinian ore, other indistinguishable Hercynian ores of Sardinia and/or Spain, and several different Alpine Mesozoic‐Tertiary mineralizations of the Mediterranean basin (Spain, Greece, Tuscany).     

基于旅游互动的背包客通用技能变化研究

通用技能也被称为通用能力,是在信息丰富的社会成为一个经验丰富的专业人才所需要的先天能力、后天能力和知识.旅游是一种非正式的学习,通过旅游互动能改变旅游者的通用技能.本文研究背包旅游者通用技能变化以说明旅游互动与通用技能变化的关系.本文通过文献、访谈,结合因子分析,完善并验证背包者旅游互动模型,将背包者旅游互动分为与环境的互动和与人的互动两种,并进一步基于旅游互动行为的特点,通过因子聚类分析,将所有样本人群分成3类.
