Sampling and analysis of geothermal fluids

Sampling of geothermal fluids presents some problems not encountered when sampling surface and nonthermal ground waters. Specific collection techniques are required to obtain representative samples because of the elevated temperature and boiling of these fluids, the effect of exposing them to the atmosphere and cooling of the samples. Sample treatment during collection depends on the analytical method to be used. When sampling wet‐steam wells, both the liquid and the vapour fractions should be collected at the same fluid separation pressure. When sampling fumarole steam, maximum information is obtained if the total discharge is collected into a single container without separating the gas and the steam condensate fractions. Silica polymerization affects the solution pH. The only way to obtain reliable pH measurement of a water sample supersaturated with respect to amorphous silica is to measure it on site, before the onset of polymerization. This paper provides an outline of the geothermal sampling techniques and analytical methods currently in use in Iceland. Sampling of hot‐water and wet‐steam wells is described, as is sampling of hot springs, fumaroles and gas bubbling through hot‐spring waters. Detailed procedures are given for the analysis of total carbonate carbon and total sulphide sulphur in geothermal water and steam condensate samples.     

Earthquake‐related temperature changes in two neighboring hot springs at Xiangcheng,China

Pre‐earthquake and postearthquake temperature changes were documented in two hot springs at Xiangcheng. Pre‐earthquake changes were documented in spring I, 13 days before and 106 km away from the M_s 5.8 Zhongdian earthquake. The 11‐year cutoff spring spouted again, and the spouted water was 24°C hotter than the former escaping gas. Postearthquake changes were documented in spring II following the 2008 M_w 7.9 Wenchuan earthquake, approximately 425 km away from the epicenter. Temperature in spring II showed a step‐like increase with a magnitude of 4°C induced by the earthquake. Spring I which is 0.3 m apart from spring II did not show a sudden change following the earthquake. However, temperatures in the two springs were identical after the Wenchuan earthquake. It indicates that the earthquake generated new hydraulic connectivity between springs I and II, and the heat transport between the two springs accounts for the postearthquake temperature changes.     

2011 Cultural heritage legal summary

Abstract

This article summarizes the legal developments during 2011 that affect archaeological heritage. Among the more significant developments were advances in and challenges to the use of international law in deterring the trade in undocumented antiquities and questions of whether artifacts on loan to U.S. institutions from Iran could be used to satisfy judgments against Iran awarded to victims of terrorist bombings. Finally, the article presents a preliminary assessment of the impact of the "Arab Spring" conflicts on cultural heritage preservation.

中国城镇化质量研究现状与热点分析

运用CiteSpace可视化软件和计量可视化分析方法,对CNKI中（1999-2019年）收录的CSSCI期刊中有关“城镇化质量”的文献进行图谱分析,对近20年来城镇化质量研究领域的发文数量与研究机构及其合作关系、城镇化质量的研究热点进行了梳理。研究结果表明：①从发文数量来看,21世纪以来关于城镇化质量的研究成果不断丰富,文献数量不断增加,但是作者之间、研究机构之间的合作关系较弱;②有关城镇化质量的研究经历了缓慢发展阶段、迅速增长阶段以及平稳发展阶段;③研究热点主要集中在新型城镇化道路、城镇化发展的协调性、人口城镇化等方面。未来有关城镇化的研究将更加注重城镇化质量的提升,注重对新型城镇化高质量发展路径的研究。     

国外交通地理学研究的知识图谱与进展

交通地理学作为人文地理学的重要分支,一直充满着活力与多样性,获得人文地理学者的广泛关注。本文基于CiteSpace可视化软件,采用Web of Science中收录1982-2014年的4840篇交通地理学论文作为原始数据,梳理了近30年的研究脉络,绘制了学科发展的知识图谱,系统地归纳了学科的研究热点与发展趋势,以期为中国交通地理学研究提供借鉴。研究发现:国外交通地理学研究方法和研究内容日趋多元化,研究视角趋向微观化,质性研究突显;初步形成城市规划学派、理论地理学派、时间地理学派等六大学术共同体;出现社会、行为、文化和流动的诸多转向,呈现出人本导向、信息导向和交叉化的发展趋势。     

热战、冷战、冷和:美国全球扩张的战略反思

发展与扩张是美国国策的一条主线。“热战”、“冷战”与“冷和”则是美国基于国内经济与社会发展而对全球扩张的依序相循的三段路径。反法西斯战争是全世界人民的胜利,美国却是世界胜局的最大受益。二次战后初期以来,美国挑起“冷战”,以“经济分流”与“民主工程”令苏联解体,使自身处于一超独大的世界之位。在“冷和”条件下,美国对发展中国家推进“改造工程”,则是其对全球扩张的新目标。三内生互动的解读,有益于人们的深度战略反思。
