20世纪的泥沙运动力学

在20世纪，泥沙运动力学的研究取得了不少突出的成绩，但与其他学科同时期的进展相比，发展还是比较缓慢的。按取得的进展来看，20世纪可分为两个阶段；在上半叶，有6项突破性进展，逐步积累，到1950年，Einstein集大成，提出了第1 个泥沙运动力学理论体系。在下半叶，进入了百家争鸣的时代，一些研究者提出了自己的泥沙运动理论体系，作者列举了8个有代表性的理论体系。受计算机时代的影响，从20世纪70年 代开始出现了根据大量实测资料，利用计算机进行回归分析而得出的阻力和输沙率公式，而不拘泥于发展新的理论。与此同时，一些与实际偏离较远的理论逐渐被淘汰。在21世纪，要搜集系统完整的资料，特别是近底层的资料，并拓宽研究领域到环境，生态等学科。     

Ergonomics and the global problems of the twenty-first century

Abstract

The world will face major ecological and social problems in the coming century, including population pressure, pollution, water shortage, urbanization, etc. To solve these problems requires changing human behaviour. What is the role of ergonomics? Can we design constraints that are perceived as freedom? Can there be a metaphysics of ergonomics in which we can find ethical values for design which transcend cultural bases?     

The Politics of US Military Research in Greenland in the Early Cold War

The focus of this article is US military research in Greenland and its role in Danish‐American political relations in the early Cold War period 1945–1968. This was a period of intense US research activity that aimed to overcome the hostile Greenlandic environment and harness it for military purposes. In the US‐Danish defense agreement on Greenland of 1951 the USA got a free hand to develop three so‐called defense areas for military purposes, while it had to seek Danish permission for research and other activities outside these areas. The two partners had differing, but mainly compatible, interests in this process. The US interest was freedom to do research on the gigantic Greenland Icecap, while the Danish authorities emphasized the protection of its sovereignty over Greenland. The article follows the US research programs in the 1950s and 1960s and Danish responses in some detail, including the intriguing and still mysterious Camp Century project and its relationship with the US Army's Iceworm plan to deploy strategic missiles beneath the surface of the Greenland Icecap.     

Prejudicial Narratives: Building Tomorrow's World Today

Film production requires world building: the power to visualise and bring to life narrative through a film's total environment. This is often entirely speculative, imagining alternative or future worlds. Here, Alex McDowell , acclaimed British production designer, producer and Professor at the University of Southern California (USC) describes his world-building, narrative approach to production design, which he consolidated in the Steven Spielberg film Minority Report (2002) that envisioned Washington DC in the year 2050. The possibilities of this storytelling technique are demonstrated by its transference into real-life projects, such as the immersive model that his production company, 5D GlobalStudio, developed for Al Baydha, a Bedouin village in Saudi Arabia.

传承与演进： 评“中国建造：现代建筑百年对话”展览

本文回顾了2022 年1月底至6 月初在宾夕法尼亚大学费舍尔美术图书馆和建筑档案馆举办的“中国建造： 现代建筑百年对话”展览。旨在呈现展览的原貌,本文概述了展览的背景和缘起,介绍了展览的具体内容和策 展思路,并回顾了展览进行过程中和结束后来自各界的反响和评价。本文将“中国建造”展置于近二十年来一 系列有关宾夕法尼亚大学与中国现代建筑关系的学术活动的框架内,强调其目标是在立足于“第一代“中国建 筑师与宾夕法尼亚大学布扎体系首次交集的一个世纪之后,审视现代建筑发展进程中的跨文化对话,揭示中国 建筑实践中的跨世纪连贯性,并对全球性建筑技术的探索和设计创作中本土身份之间的关系进行进一步地诠 释。文章指出本次展览是对中西现代建筑“百年对话”主题的一次有意义的深入扩展性研究,并提出了中西建 筑文化交流这一宏观话题进一步研究的可能方向。     

Sharing Rivers for Peace,Development, and Security

Abstract

Water is a finite resource, and with the considerable upsurge in population, urbanization, and industrialization, it is also becoming an increasingly scarce resource. Many countries in the world rely on river waters, and many of those rivers are shared by two or more countries. Dams on those rivers have been a major source of tensions, disputes, and, in some cases, even conflict between riparian countries because dams could result in massive diversion of river flows. Those developments have, inter alia, highlighted the relevance and importance of the principles of international water law, as reflected in the United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses. The World Commission on Dams has also underscored the importance of, and elaborated on, those principles with regard to dams on shared rivers. This article discusses and analyzes the recommendations of the Commission in this area, and compares them with the principles of international water law as enunciated in the United Nations Convention

21世纪中叶西南国际诸河水能资源开发设想

西南国际诸河包括澜沧江、怒江、红河和伊落瓦底江,4大流域在我国境内总流域面积约41万km^2,本文论述诸流域水能资源量分布特点及其开发利用条件,开发程度,根据化、西南地区各（区）21世纪中叶经济发展,电力规划和区域电网结构设计的可能性,开发西部水能资源,实现了“西电东送”的目标,提出分阶段水电开发设想,重点是21世纪前20年。西南国际诸河水能资源丰富,根据初步复核的技术可开发装机容量为5298．17万KW,年发电量2577．44亿KW.h。装机容量按河流分澜沧江57．71％,怒江占30．38％、红河和伊洛瓦底河两江仅占11．91％,至1995年开发程度仅为4．93％,说明西南国际诸河尚有大量的水能资源待开发。为加快我国西南部地区经济的发展,促进东西部经济共同繁荣,必须加大西南国际诸河的水能资源开发利用,这也符合目前国家的西部开发策略。
