With the aid of the 'butterfly effect' theory, this article investigates the role of ordinary individuals, both Chinese and American, in the formulation, implementation and promotion of 'Ping Pong Diplomacy', which brought about the US‐China rapprochement in the early 1970s. Through examining the twists and turns in the process of 'Ping Pong Diplomacy' making, this study intends to bring one's attention to a number of seemingly less significant historical episodes and their long-term impact on US‐China relations. Like small butterflies whose spontaneous actions can generate unexpected climatic changes, the various individuals in this study, including players and officials of the table-tennis teams, low-ranking diplomats and journalists, played an indispensable part in bringing forth a dramatic transformation in US‐China relations, which in turn altered the Cold War climate in general. 相似文献

我国复杂产品系统自主创新研究 总被引:4,自引:0,他引:4
在比较优势逐渐丧失和存在发达国家压制的情况下,自主创新对于发展中国家技术追赶战略的实现至关重要.复杂产品系统在现代经济发展中发挥着重要作用,而我国复杂产品系统技术水平与发达国家相比差距较大,所以复杂产品系统的自主创新成为理论和实践中关注的焦点.通过研究发现:引进消化吸收再创新是发展中国家技术能力发展的一般轨迹,我国复杂产品系统自主创新的实现也应遵循这一路径;由于我国作为创新主体的企业大多存在技术、资本等各种资源相对匮乏和复杂产品系统涉及技术领域多、开发规模大、创新风险高等特性的问题,合作创新网络就成为我国复杂产品系统自主创新的最佳组织形式;面临发达国家的技术封锁策略,我国复杂产品系统自主创新依赖于国内技术集成创新来实现.我国干熄焦技术装置自主创新的实践验证了以上观点. 相似文献

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

The railway sector in China has undergone several major rounds of reform and institutional restructuring since 1986. These reform initiatives have largely been unsuccessful due to strong resistance from vested interest groups. The development of China's railway sector has raised some challenging issues that include the centralization of power in the Ministry of Railways (MOR), state monopoly control, rampant corruption and the accumulation of a huge debt burden. The 2013 railway reform initiatives have provided very little in the way of concrete measures to deal with these thorny issues but have instead created more controversy and problems in an already crisis-ridden sector. For the railway industry, the transformation from the mixed-function MOR to a monopolistic China Railway Corporation (CRC) will not necessarily lead to better railway management. 相似文献

监狱行刑理念是监狱行刑活动的灵魂,是监狱行刑的内在精神和最高原理,对监狱行刑的趋向性起着指引和引导作用。从当前我国监狱的行刑工作考察,主要存在监狱行刑的功能、罪犯权利保障、监狱行刑的模式等方面的理念冲突,影响制约着监狱行刑的文明化、法治化。监狱的行刑理念采用国际标准还是国内标准或是折衷标准,应该和我国的社会主义市场经济、政治民主和思想文化意识结合起来,综合各因素的共性,切中监狱行刑的契合点,建构适合我国国情的监狱行刑理念。 相似文献
