氧化铁在钧瓷天蓝、天青系列釉色中的着色作用以及乳光蓝色问题,一直是学术界争论的焦点。本研究通过放大氧化铁含量的实验验证方法,通过SEM(scanning electron microscope-扫描电子显微镜)、EDS(Energy Dispersive Spectrometer-能谱仪)、XRD(X-ray diffraction-X射线衍射)等分析方法,重点研究了基础组成和分相结构对釉中氧化铁呈色的影响。同时,作者通过验证研究得出,钧瓷天蓝、天青系列釉色中,真正起呈色作用的是釉中的氧化铁等着色剂,第二相微粒散射呈色并非钧釉的普遍现象,或只是辅助呈色作用。 相似文献

National and international regulatory standards require industrial risk assessment, taking into account natural hazards including earthquakes, in the framework of Quantitative Risk Analysis (QRA). Seismic fragility analysis of industrial components may be carried out similarly as what has been done for buildings, even though some peculiar aspects require the development of specific tools. In the present paper a contribution to the definition of a rational procedure for seismic vulnerability assessment of standardised industrial constructions in a probabilistic framework is given. The method covers a range of components of the same structural type. Seismic reliability formulation for structures is used. Both seismic capacity and demand are considered probabilistic with the latter assessed by dynamic analyses. The application example refers to shell elephant foot buckling of unanchored sliding tanks. A regression-based method is applied to relate fragility curves to parameters varying in the domain of variables for structural design. 相似文献

A Palestinian geographer and urban planner discusses one of the territorial challenges that will likely emerge in the process of building a future Palestinian state. More specifically, he outlines how looming population pressures (high density in tandem with rapid natural increase and return of displaced refugees) will require that investments to support economic growth and new construction be organized within a national settlement system based on the existing urban hierarchy. In addition to describing the elements of such a system ("developed urban axis of Palestine"), the paper also covers the effects of public opinion and shifting political alignments within the territories on shaping the conceptualization of a future Palestinian state. 相似文献

The Hu Jintao administration used the ‘four‐in‐one’ wording for the overall arrangement of development in China, that is, economic development, political development, cultural development and social development. The term ‘soft power’ was adopted to conceptualise the cultural development dimension. This paper used a tripartite taxonomy to examine Chinese approaches to soft power, as ‘resources’, as ‘strategies’ and as ‘outcomes’. Soft power in China was mainly used in a domestic policy context to mean cultural resources to be amassed and accumulated. Soft power could be measured as part of its comprehensive national power and compared with the hierarchical status of other nation states. Soft power as strategies meant using power softly in seeking normal economic and political advantages abroad. Soft power as outcomes meant the rise of China and its cultural renaissance. 相似文献

本质为地理过程的全球化与跨国公司相伴而来,其浸入区域、城市具有时空差异性。本文以八家大型跨国零售企业为例,研究全球化浸入中国城市的时空演化过程及影响因素。研究发现:第一,全球化浸入表现出明显的空间推移规律,即稳定的"沿海-内陆"深度格局,以及"东广西疏"转向"南袤北稀"广度格局;第二,全球化浸入中国城市遵循规模等级推移规律,包括人口规模、经济发展水平以及行政等级;第三,人口规模、对外交流水平对全球化的浸入影响显著性稳定,开放政策、城市区位因素弱化,居民收入水平影响增强。 相似文献
