现代海战中国外“矛”与“盾”武器的博弈

反舰导弹（矛）与舰载反导武器（盾）之间的斗争是现代海战重要格局之一。美俄二大军事大国在矛与盾的发展上,均以对方为假想敌,研究使自己的矛如何突防对方的盾,以及自己的盾如何拦击对方的矛。由于历史条件,国家政治需要和本国的技术优势不同,二国发展矛与盾的指导思想和设计准则,以及在攻防策略上都有很大不同。文章从深层次分析这些不同特点,并探讨它们的发展走向。     

电渗透防水防潮技术的工程应用

地下工程防水防潮一直是工程界的难题,传统技术存在难根治、易反复的缺点。选择某一洞库进行电渗透技术工程试点研究:先详细介绍电渗透技术和施工工艺情况;再采用在工程内布置电极并施加脉冲电压的方法,利用电场力迫使水分向工程外岩体移动,达到降低工程内部湿度、防水防潮的目的。工程应用表明,电渗透防水防潮技术拥有效果明显、运行费用低等突出优点,具有推广前景。     

Saudi Arabia's defence offset programmes: Progress,policy and performance

This paper discusses the performance of Saudi Arabia's defence offset programmes. The Kingdom is involved in some of the World's biggest defence offset agreements and a review of the problems it has faced and the policies it has introduced provides a useful insight into that part of the international defence market where trade and development meet.

The paper reviews the origins and development of Saudi Arabia's major defence offset programmes. Saudi policies towards defence offsets are outlined before assessing the practical impact of the programmes themselves. The author concludes that Saudi Arabia's offset projects have had only a minor impact on the Kingdom's economy to date and makes a number of policy recommendations which are designed to enhance the utility of the programmes in the Kingdom's drive to enhance and diversify the technological base of its economy.

Dynamic regulation on innovation and adoption of green technology with information asymmetry

This study investigates a regulator's dynamic policy to motivate firms' research on and adoption of green technology. In the proposed model, a firm makes unobservable efforts and can hide the technology's arrival from the regulator to avoid adoption costs. We find that the optimal policy follows a simple structure and induces part-time efforts, rather than the maximal effort reported in previous studies. In particular, the regulator should offer no subsidy before the arrival of a technology report, provide a one-time subsidy contingent upon that report, and always set a termination deadline. At the deadline, the firm is forced to select an external option that is associated with social costs. The optimal report-based subsidy decreases with time. Under the optimal policy, the firm works until an effort deadline, makes no effort thereafter, and reports the technology as soon as it arrives. This study also characterizes the necessary and sufficient conditions under which the optimal policy reduces to one that leads, in terms of throughout time, to effort that is maximal or minimal. Our results indicate that policymakers should implement a policy that compensates firms more in the present and less in the future.
