Emergency centers, communication systems, and hospitals are essential infrastructures for emergency rescue and subsequent reconstruction activities. An investigation into the Nepal 2015 earthquake sequences found that the visited government offices were functioning normally 40 days after the main shock; that the local media failed to coordinate with the entire society at the beginning, but mobile phone-based communication recovered quickly; and that the hospitals in high-intensity areas were badly damaged as a result of improper design and adverse site configuration. Recommendations are proposed to enhance the aseismic capacity of structural and non-structural components using earthquake early warning and base isolation. 相似文献

地理学的安全感研究:基于地点的综合理解、应用及展望 总被引:2,自引:0,他引:2
安全是人们对日常生活空间的基本需求,安全感则反映了人们希望免于危险的主观感知。20世纪90年代以来,基于地点的安全感研究成为社会地理学及其相关学科的重要议题,学者们重视探索地点的物理、社会-文化环境特征与人的安全需求、生活质量之间的关系。运用地点理论开展安全感研究,一方面倡导建构具有情感、价值、意义的安全地点,另一方面为预防犯罪的跨学科安全空间综合研究提供了平台,促使人文地理学通过整合社会学、环境心理学等学科的研究成果完善社会-生活空间理论,提高人们的社会-生活空间质量。本文通过回顾地理学、社会学、犯罪学、环境心理学等相关学科对犯罪地理与安全感的主要研究成果,梳理了不同学科的研究兴趣及其最新进展;在此基础上讨论了人文地理学基于地点理论研究安全感的主要方向及趋势,旨在建构基于地点理论的安全地理学研究框架,为人文地理学社会-生活空间研究提供借鉴。 相似文献

Samples of celadon were collected from the Altar Guan Kiln in Hangzhou, and from the Xiaomeizhen and Xikou Kilns, two subordinate kilns of the Longquan Kiln producing black‐body celadon called Literature Ge. Both the elemental contents in the sample bodies and the glaze were measured. The results reveal that the sample bodies contain fingerprint information for provenance, while this was lost in the glaze during the production process. The TiO2, MnO and Rb2O contained in the bodies are fingerprints to distinguish between celadons from the Xiaomeizhen and Xikou Kilns. In the Altar Guan Kiln, some low‐TiO2 samples were found and their body colour is much lighter than some others, but they do not differ with regard to iron content. This indicates that both titanium and iron are indispensable for the blackness of the bodies: they may react to form some black minerals during the firing process. Ultimately, samples from the Literature Ge and Altar Guan Kilns differ in their body constituents. Principal component analysis reveals that the samples can be divided into two groups, corresponding to the two different areas. 相似文献

为了避免核武器、核军备竞赛再次在拉美出现,古巴导弹危机之后,一些拉美国家提出了建立拉美无核区的设想。对该提议,美国经过考察发现此举同样有助于满足其国家安全需求,这使得约翰逊政府原则同意支持按照美国标准建立。然而,由于美国政府不同部门之间对建立拉美无核区的细节问题存有分歧,使得美国虽然促成了拉美无核区条约的缔结,但它最终却没有签署该条约。 相似文献

The Compositional study of ceramic samples from tombs dating to the Zhou Dynasty at Xiaoshan,Zhejiang Province (China)

Xiaoshan in Zhejiang Province was an important ceramic production area in ancient China. During recent years, local archaeologists have found a number of mound tombs dating to the Zhou Dynasty and the Spring and Autumn period. Many shards of stamped stoneware and proto‐porcelain have been unearthed from these tombs. In this paper, we report how we collected ceramic shards from tombs and samples from local ancient kilns as reference materials in order to clarify their relationship. We have used the energy‐dispersive X‐ray fluorescence technique to analyse the chemical composition of the ceramic samples. The results indicate that some of the tomb artefacts may be imported from other production areas. We infer that the other tomb samples were produced at local kilns, but due to production process–related compositional differences, there are small differences in chemical composition between different categories of samples. 相似文献

<正>目次一《保训》释文二竹书之"埶"与测阴阳三舜求地中的故事四微变地中的故事五地中变迁的考古学与文献学证据六周人居中而治思想的传承七地中变迁与夏商都邑的关系八结论清华大学所藏战国竹书《保训》是一篇颇具价值的先秦古遗书,自刊布以来,学者研释不绝,对通晓文意,揭示其思想有很大帮助。然因竹书某些关键字词的释读多有争议,致学者就竹书内容的理解仍颇存分歧。笔者以为,竹书宗旨乃在阐明居中而治的传统政治观,其中尤为重要者,则在于保留了久已失载的有关古人对于地中的求测及早晚地中变迁的史实。今就相关问题阐释考述。 相似文献
