便携式X射线荧光光谱仪在西藏寺庙木材防腐透入度检测中的应用

木材防腐处理是一项专业性很强的工作,在西藏偏远地区缺乏专业设备的条件下要保证处理效果,需特殊的处理工艺与高效的检测手段。透入度和载药量是衡量木材防腐处理效果的两个重要指标:载药量可通过换算得出结果；透入度一般需要在实验室使用仪器检测。便携式X射线荧光光谱仪的发明使得以前需要在实验室开展的工作可在现场完成,该仪器通过检测木材中防腐剂所含的金属元素确定透入度,具有检测速度快、操作简单的特点。研究结果可为西藏偏远地区寺庙木材防腐防虫处理工程质量控制提供借鉴。     

高质量发展视角下黄河流域城市网络的结构演变与影响因素研究

城市作为人口、产业等要素聚集地，基于多要素解构城市网络对明确城市高质量发展的内涵具有重要作用。本文通过修正经典引力模型和社会网络方法，分析了高质量视角下黄河流域城市网络结构演变特征，利用QAP方法探求其影响因素。结果表明：(1)黄河流域城市网络基本形成了以郑州、西安、济南、太原、兰州等省会城市为核心，辐射至周边城市的网络结构，网络密度逐渐增大但整体较低，网络通达度相对较高且稳定。(2)城市网络社群内部关联高于社群间关联，说明高质量发展视角下黄河流域城市网络社群溢出效应主要以社群内溢出为主，社群外溢作用较少。(3)区位条件、交通基础设施、产业结构、政府支持强度、科技创新的差异对黄河流域高质量发展的城市网络演变有显著影响。     

Uses of Gypsum in Spanish architectural heritage: Typologies and some unique construction techniques

ABSTRACT

In Spain, gypsum and its many typologies play an important role as a construction material in Spanish architectural heritage. Its historical use is mainly a direct consequence of the abundance of gypsum deposits and a constructive tradition which began in ancient times. In addition to being a sign of constructive identity, gypsum is a clear example of the strong link between traditional architecture and the natural resources of the territory. The aim of this article is after to identify gypsum deposits and gypsum architectural heritage found in different parts of Spain and to explain the different gypsum typologies—other than powdered gypsum—used. Finally, the most unique construction techniques are described, differentiating between structural elements, partitions, and enclosures, as well as architectural elements and surface finishes.     

Cellular Automata for Studying Historical Spatial Process of Traditional Settlements Based on Gaussian Mixture Model: A Case Study of Qiaoxiang Village in Southern China

ABSTRACT

The spatial evolution of traditional rural settlements is a natural process that occurs without professional development planning. With rural spatial organization now being stimulated by China’s economic structure adjustment, making top-down plans match bottom-up spatial principles is important for the continuity of rural communities. In this research, a Cellular automaton based model was introduced to describe the historical spatial rules of rural settlements based on a traditional village in Southern China. In order to reproduce the rural spatial characteristics and laws that were close to the actual situation truthfully and distinctly, in this model, we refined the growth process into three cyclical steps, and used a Multivariate Gaussian Mixture Model for the evaluation of spatial transition potential. Through historical simulation, evaluation of the current status, and future spatial predictions, results showed that: (1) the growth during the whole spatial process maintained logical consistency for optimal selection; (2) certain houses in the southeast region should be carefully protected as a core living culture exhibit, while the best utilization of other homes should be considered; and (3) the most probable region of growth for tourist services or new housing estates is scattered along the river in the central area of the village.     

Fuelling the Fires: The Contribution of Wood Charcoal Analysis to a Landscape Scale Project at and Around Pre-Conquest Iron Age Silchester and a Reflection on Its Wider Implications

ABSTRACT

The contribution of targeted wood charcoal analysis (anthracology) to understanding of the 1st millennium BC Pre-Conquest Late Iron Age oppidum and transition to Early Roman town life at Silchester and nearby late prehistoric hinterland sites investigated by the Silchester Environs project is considered. Attention is given to whether substantive differences in charcoal assemblages of varying size and origin are discernible through time and space, and to their value in elucidating landscape, environment, woodland structure, taphonomy, site function and lifestyles. This paper aims to take stock of the work so far and reflect on what lessons can be learned within and beyond the project. Site-level data are summarised and contrasted for the reader, while full context-level interpretation is published elsewhere [Barnett Forthcoming a. “The Early Roman Wood Charcoal and Waterlogged Wood at Silchester.” In Silchester Insula IX: The Claudio-Neronian occupation of the Iron Age Oppidum.

日常消费空间中的情绪产生与作用机制——基于南京的实证研究

本研究引入消费者行为学的"认知-情绪-行为"模型，并加入空间要素建立整体框架，采用结构方程模型与质性研究相结合的方法，探讨消费空间中影响消费者情绪产生的因素以及情绪对居民生活满意度的作用。研究表明，积极情绪的产生主要受到个人价值观的鲜明度、消费场所物质环境的宜人度和消费场所中社会交往的深度影响；消极情绪的产生主要受到个体经济地位和个人价值观的鲜明度影响；积极情绪与消极情绪均显著影响消费者的生活满意度，积极情绪会导致较高生活满意度的产生。本研究从情绪的角度阐释消费空间和人的关系，是从微观尺度上对情绪地理学研究的新探索，同时也为城市消费空间研究与规划提供了人本主义的新视角。
