A Method for Selecting Ground Motions that Considers Target Response Spectrum Mean and Variance as Well as Correlation Structure

This study proposes a method for selecting ground motions from a ground motion library with response spectra that match the target response spectrum mean, variance, and correlation structures. The proposed method is conceptually simple and straightforward. In this method, a desired number of ground motions are sequentially selected from first to last. The accuracy and consistency of the proposed method are verified through comparisons of the ground motions selected using the proposed method with those selected using conventional methods. This study shows that the seismic responses of the frames vary according to ground motion selection and correlation structures.     

Firing temperature of a clay core sample in a bronze tripod from Daxinzhuang Site in China using TL techniques

In this paper, we studied the thermal history of a clay core sample from one leg of a bronze tripod unearthed at Daxinzhuang Site, Shandong, China. The properties of the luminescence signals of quartz depend on the maximum temperature at which the quartz was annealed in the past. We examined the feasibility of measuring the thermoluminescence (TL) sensitivity change of quartz for exploring the firing temperature of archaeological materials. The sensitization factor of the 110°C TL peak (S₂/S₁) and the ratio of the 210°C TL peak to the 110°C TL peak at different annealing temperatures were utilized to unveil the firing temperature in the clay core sample. The firing temperature of the clay core sample was approximately 700°C–800°C, proving the clay core has been fired. This result proved that the clay core has been fired by human agencies and indicated on the temperature of the clay core in drying and firing given by the foundry workers before the actual casting step.     

绅士化语境下的失所现象:概念溯源及研究综述

失所（displacement）现象历来受到国际学界的广泛关注。本文主要探讨因绅士化而造成的失所现象,并对西方理论体系和实证研究进行较全面的综述。因绅士化造成的失所可分为直接性失所和间接性失所。依据不同的形成原因,直接性失所分为物质性失所和经济性失所,而间接性失所包括排斥性失所和潜在性失所。在笛卡尔式空间观的主导下,西方主流失所研究历来偏重直接性失所,而忽视间接性失所。本文认为,间接性失所背后的列斐伏尔空间观应纳入到失所理论体系中,以更好地指导失所实证研究。本文指出,结合中国现实,对失所现象进行理论化与概念化,对于转型期中国可持续城市发展具有现实与深远的意义。     

胡汉交融视角下唐代披袍女俑形象新探

唐代墓葬陪葬俑、石质葬具与壁画出现一些女性披袍形象,亦见于敦煌、新疆等佛教洞窟壁画,披袍形制、装饰展现出多元文化交融特征,属于广义胡服体系,在北朝至隋唐时期女性易装背景下,反映了这一时期女性身份与地位的变化、女性服饰中西域文化的影响以及胡汉交融之性别重构与意义。     

16世纪至20世纪60年代滇池沿岸的 低田与深水稻种植

明清以降,滇池在岁修制度下常年疏浚海口,水域范围基本稳定,但受季风气候影响,其水位存在明显季节性变化,夏秋上涨,冬春下降,主要表现为沿岸低田在雨季即周期性被湖水淹没的特点。随着滇池流域坝田开发趋于饱和,滇池沿岸低田的深水稻“水涨谷”,在明清之际逐步系统种植,实现滨湖低田稻作与滇池水位季节性变化的生态耦合。这种局面到20世纪60年代末彻底改变,入滇河道上游大小水库的修建,使滨湖低田逐渐干田化,水涨谷生长的水域环境发生变化。观察滇池水域环境与稻作生态互动的关系,发现当区域环境呈现出长时段的规律性变化,就可能变“害”为“利”,这是人与自然相处中适应并利用自然的智慧展现。     

对称赞语回应之“thank you”的研究

致谢作为一种和谐性的言语行为,本质上是礼貌的,与道歉,命令,祝贺和许诺一样,它与人们的日常生活密切相关。致谢同时又是我们日常生活中发生频率很高的一种言语行为。正确地表达致谢有着重要的社会价值。本研究从理论上增进了我们有关致谢言语行为的知识,从实践上可以帮助我们建立一个良好的人际关系和和谐的社会氛围。     

成渝经济区县域经济差异的空间分析

借助ARCGIS软件中ESDA分析模块和统计功能,并与传统统计方法加权变异系数相结合,以县域为研究单元,以人均GDP和GDP为测度指标,初步探索了1999-2008年成渝经济区县域经济差异的空间格局变化。结果表明,成渝经济区县域经济总体差异呈逐渐扩大趋势,经济发展水平、经济增长能力和经济密度的空间特征三者的空间格局基本吻合,形成以成都市区和重庆市区为核心的圈状空间结构,且这种格局在不断的强化;高速公路发展轴经济带动作用不明显,广大地区经济仍处于落后状态;现发展阶段,核心区的极化作用占主导,区域经济发展极不平衡。     

古城西安住宅消费市场满意度重要性与差异性分析

本文以古城西安为例,在第一手调查资料的基础上,构建了住宅市场消费满意评价模型,采用消费者指标选择累积统计的方法,构建了重要性与满意差异模型,进行了重要性与满意差异分析。研究结果显示:评价项目中,住房价格与中观小区空间因素满意评价较低;满意且重要区域主要集中于宏观区域因素;重要不满意区域,价格因素主导突出。
