本文以美国斯坦福大学胡佛研究院档案馆藏蒋介石日记、台湾"国史馆"藏蒋介石档案和外交部档案、广东省档案馆藏财政厅档案、中国第二历史档案馆和重庆档案馆编四联总处史料集、民国报刊杂志等原始史料为依据,考察了国民政府管控侨汇的机构、政策、流向变迁历程及其成效。认为战时侨汇是外汇的重要组成部分,是国家金融抗战和军事国防联动布局的关键物资,国民政府对侨汇管控有其金融抗战和国防战略部署的双重需要。抗战时期国民政府的侨汇管控存在着复杂的政策调整和隶属机构的变迁,这些措施增加了海外侨汇流入祖国。四联总处、财政部、中国银行和中央银行对战时侨汇管控做出重要贡献。文中1940—1945年度中国银行经收美元和英镑外币侨汇数额的统计图,填补了战时侨汇本币和外币统计数据欠缺的空白。  相似文献

本文介绍了满洲电业株式会社的发展历程、代表性发输配电设施、伪满洲国覆灭时的状况。纵观“满电”的发展史可以发现,这既是高度垄断的电力生产、管理机构,也是伪满洲国傀儡政权的重要经济支柱和日本帝国主义侵略、掠夺中国东北的重要工具。  相似文献

Superelastic Shape Memory Alloys (SE SMAs) are unique alloys that have the ability to undergo large deformations and return to their undeformed shape by removal of stresses. This study aims at assessing the seismic behavior of beam-column joints reinforced with SE SMAs. Two large-scale beam-column joints were tested under reversed cyclic loading. While the first joint was reinforced with regular steel rebars, SE SMA rebars were used in the second one. Both joints were selected from a Reinforced Concrete (RC) building located in the high seismic region of western Canada and designed and detailed according to current Canadian standards. The behavior of the two specimens under reversed cyclic loading, including their drifts, rotations, and ability to dissipate energy, were compared. The results showed that the SMA-reinforced beam-column joint specimen was able to recover most of its post-yield deformation. Thus, it would require a minimum amount of repair even after a strong earthquake.  相似文献

Field ambient vibration tests and modal identification using a Bayesian approach are conducted for a building made of multi-grid composite wall structure and divided into two adjacent parts by a seismic joint, to investigate the dynamic characteristics of the special structural type and the effects of the infilled seismic joint. It is found that dynamic interactions between the two structural parts exist possibly induced by the infill of the building separation. Natural frequencies obtained from other two modal parameter identification methods and modal analysis results of finite element models considering dynamic interactions agree with those identified by the Bayesian approach.  相似文献

Has feminist geography really lost all relevance? This paper examines what the revitalisation of interest in feminist thought and practice, especially in Australia, means for geography. We illuminate the trajectory of the feminist revitalisation in new media and beyond through developing a spatial analysis influenced by Rose and Fincher. Notions of paradoxical space and issue publics inform this reading of two pivotal moments in the feminist revitalisation: first, the creation of Destroy the Joint, a campaign launched and maintained in Facebook and Twitter spaces; and second, the Australian Prime Minister Julia Gillard's speech against sexism and misogyny in Parliament in October 2012. Both these moments, coming from political and public spaces, received worldwide interest, and we critically examine the context and ramifications of these instances while situating the institutional processes surrounding them within the growing feminist revitalisation. In so doing, we argue that these Australian‐based cases indicate a growing feminist movement that is open and multiply focused, connecting personal politics to public campaigning, and achieving material impacts. We conclude that developing a feminist geography of new media is a challenging task, as these spaces circumvent and renegotiate traditional spatial dimensions – including scale and place – through their dynamic networks. It is, nevertheless, a task worth doing.  相似文献

Many existing reinforced concrete (RC) structures around the world have been designed to sustain gravity and wind loads only. Past earthquake reconnaissance showed that strong earthquakes can lead to substantial damage to non-seismically designed RC buildings, particularly to their beam-column joints. This paper presents a novel retrofit method using buckling-restrained haunches (BRHs) to improve the seismic performance of such joints. A numerical model for RC joints is introduced and validated. Subsequently, a new seismic retrofit strategy using BRHs is proposed, aimed at relocating plastic hinges and increasing energy dissipation. The results indicate the retrofit method can effectively meet the performance objectives.  相似文献

This research was carried out to investigate the seismic performance of RC beam-column joints under acid rain circle via comparison of energy dissipation behavior and failure mechanism of joints with different corrosion levels and axial compression ratio. At the initial corrosion level, the strength, ductility, and energy consumption of RC beam-column joints improved slightly; at a later stage, the bearing and deformation capacity decreased as the corrosion rate of steel rebars increased. The test shows that with the increasing of the axial compression ratio, the initial stiffness and ultimate bearing capacity of the joints will increasing if the corrosion levels are the same, but the ductility of that will decrease.  相似文献

日本侵华战争期间,在日本国内和中国伪政权统治区曾分别形成了规模庞大的东亚联盟运动。东亚联盟运动以“王道主义”为指导理念,以“国防共同、经济一体化、政治独立、文化沟通”为基本内容,从思想上、文化上为日本独占中国、称霸世界的目的服务。日本的东亚联盟以尊重中国的“政治独立”相标榜,比日本国内其他侵略理论和“兴亚”运动更加具有欺骗性。汪精卫伪国民政府的东亚联盟运动则与新国民运动相配合,旨在加强伪政权的统治,为投敌行径制造理论根据。  相似文献

联省自治运动是20世纪20年代中国改良主义思潮的一次重要尝试,是国家政体由君主制走向共和制的变革中地方政制相应变革的补充。孙中山反对联省自治,他认为联省自治势必会阻碍国家的统一;而极力主张地方自治,但强调地方自治不等于忽视中央政府的领导与国家的统一。  相似文献
