中学历史教材之中汉代西北丝绸之路插图,图中中段路线南北道分途地当起自鄯善,并非敦煌玉门、阳关,南道支线分歧地当起于皮山,并非于阗。除插图所示自大宛可直抵安息路线之外,自皮山西南行,越过葱岭抵印度河流域,经今克什米尔、巴基斯坦东北部、阿富汗西南、伊朗高原亦可抵达安息。  相似文献

校园环境是校园文化建设的主要载体、主要内容和主要表现形式。从校园文化建设的高度出发,校园环境将不再是传统观念中所理解的那种简单的空间概念,进行环境建设必须从文化建设的思路去认识和思考,而进行文化建设也必须依靠环境建设的内容来表达和实现,二者不可分割,这反映了物质与意识的辩证关系。校园环境建设中精神环境的概念需要单独提出来,它是校园文化建设的重要内容,更是校园文化建设的难点。华山中学在校园环境建设方面有着自身的理解和认识,做出了一些有益的尝试,今后还将在这方面进行更深入地探寻,努力打造富有生命力和自身特色的校园文化。  相似文献

As worries have grown about global warming and the sustainability and price of fossil fuels, the demand for nuclear energy has increased, and nuclear power is increasingly viewed as a reliable and clean resource. However, the so-called nuclear renaissance coincides with an international security environment in which the norms of nuclear nonproliferation seem to be eroding. Turkey, a non-nuclear weapon state, plans to generate nuclear power to meet future energy demands, but it is aware of and concerned with regional proliferation trends. Questions have also been raised regarding Ankara's rationale for using nuclear energy, as well as its potential motivations and capabilities regarding future proliferation. This article will provide an overview of Turkey's nuclear energy history and plans, as well as the proliferation-related questions that could arise; it will also look at the domestic debate on nuclear energy and Turkey's status as a non-nuclear weapon state.  相似文献

The Middle East is a crucial region for the global nonproliferation regime. In 2010, the state parties to the Treaty on the Non-Proliferation of Nuclear Weapons proposed a conference on a Middle East Weapons of Mass Destruction-Free Zone. The nuclear weapon-free zone model, on which this idea builds, has achieved important results in other regions, but faces especially stark challenges in the Middle East. However, the attempt to apply the boldly imaginative zone approach to the Middle East holds promise for building a more inclusive dialogue on nonproliferation and regional security.  相似文献

The article presents and analyzes the US extended deterrence commitments in the Middle East as well as those provided by regional states, and assesses the effectiveness and credibility of these commitments. The article then proceeds to analyze a situation wherein Iran successfully develops nuclear weapons. It considers first the security requirements and alternatives of Gulf Cooperation Council (GCC) states, and then proceeds to assess the stability—or instability—of an Israeli-Iranian nuclear balance. The enhancement of US extended deterrence in the region is required in order to deter Iran, reassure allies, and contribute to the stability of an Israeli-Iranian nuclear balance. The article also discusses several contextual issues, such as: the future form of US extended deterrence; distinguishing between the latter and other US extended deterrence commitments; and the different approaches of specific GCC states and Israel.  相似文献

The engagement of the Atlantic Alliance in the Middle East dates back to the founding of the Alliance. With one eye on this history and one eye on current controversies, this article investigates the preconditions for and nature of the allies' engagement in the region in order to assess whether the Middle East today is causing a rupture within the Alliance. The article finds that the Alliance was never likely to engage as one in the region. The Alliance instead guarded its cohesion by either letting the Alliance leader, the United States, take a lead role or by acting as a coalition enabling framework. This latter option has prevailed since the early 1980s. Today, NATO can preserve its cohesion and simultaneously engage in the region if it continues this legacy of coalition-making from within the allied framework. Conversely, an effort to engage collectively in the region will likely set of internal tensions to the extent that the Alliance itself will be at risk.  相似文献

The Christian resistance to the Arab invasion of Spain in 711 tends to be glossed over as a sideshow in what is usually presented as the inexorable progress of the conquest. This reflects the bias of our meagre sources, which mostly take the Arab perspective. Nevertheless, with close consideration and careful handling of these sources, we can draw from them an impression of a persistent insurgency that presented a real problem to the Islamic authorities and induced them to take both political and military countermeasures. This paper suggests how the resistance formed, its organization and tactics, and why the Arabs were unable to suppress it.  相似文献

As part of the next phase of the Global Jihad, al Qaeda has been committed to winning popular support among Muslims. Ayman al-Zawahiri and the al Qaeda inner circle recognise that a global terror movement and civil conflicts in the Middle East, brought about by the Arab revolutions, necessitate different operational methods. As such, they have disavowed the Islamic State of Iraq and al-Sham for their insubordination and unconstrained tactics, a move that has implications for the Middle East, international relations, the legitimacy of the al Qaeda leadership, and the future of the Global Jihad.  相似文献
