论WTO对中国的过渡性贸易政策评审机制

中国入世需要履行的特殊义务之一是接受WTO总理事会对中国的过渡性贸易政策评审.在人们更多地关注该制度给中国带来歧视性待遇的同时,我们还应认识到该制度存在的制度缺陷,以致该制度的运行并没有能有效地避免中国与WTO其他成员方之间的贸易争端.一个不能有效运行的机制最终将逐渐地被可以有效运行的机制所补充甚至替代.因此我们有理由认为,该制度无论对中国抑或对今后其他可能加入WTO的成员方都是不必要的,制度设计者们应当引以为戒.而作为承诺方的中国,仍然需要认真履行自己的国际义务.     

Development of dual technology roadmap (TRM) for open innovation: Structure and typology

Today, innovation is no longer viewed as taking place within a single firm – but opening up the innovation process is still not a simple task. In open innovation, the mechanisms of incorporating external resources into the development process need to be carefully managed. This paper suggests a dual technology roadmap (TRM) that considers both internal and external firms. First, we introduce the concept of a dual TRM that considers partner resources as well as internal resources. Second, we suggest the structure of a dual TRM that uses dual planning objects. Third, three types of dual TRM are suggested, with three case examples.     

超宽带探地雷达中TRM-SAR成像技术研究

将时间反转镜成像技术和SAR成像技术相结合,通过理论分析和仿真实验将它应用到超宽带探地雷达成像中。实验采用了粗糙地面和电参数随机的泥土真实反映复杂探地环境。将相应的时间反转镜成像技术-SAR成像结果与时域后向投影成像算法进行了对比,结果显示,时间反转镜成像技术凭借其统计自平均特性和空时匹配滤波特性,能够为超宽带探地雷达系统提供更高分辨率的成像结果。
