China's Foreign Trade 2005年第23期 20-23页

作者： By Xu yuxuan sun Yongjian

The President of the Republic of Korea (ROK) Roh Moo-hyun announced that Ko- rea fully recognized China’s market economy status. Roh’s announcement was made during a joint press conference with Chinese President Hu Jintao. who was on a state visit to ROK in November. China is now the largest trading part- ner of ROK, with trade volume between the two countries expected to reach 100 billion US dollars this year. The two leaders agreed that the bilat- eral trade volume should be doubled to 200 billion US dollars by 2012. A significant milestone having been reached between the two countries, what kind of impact can be expected to follow from the events in regards to the bilateral economic and trade relations between China and ROK? With such questions in mind. China’s Foreign Trade reporters in- terviewed Kim Ha-joong. Ambassador of ROK to China.

三元乙丙橡胶(ethylene propylene diene monomer,EPDM)增强绝缘作为高压电缆附件中的关键部件,其电树枝化和绝缘界面沿面放电问题严重。为改善EPDM本体和绝缘界面的耐电性能,采用4种电压稳定剂对EPDM进行改性,系统地研究电压稳定剂对EPDM交流耐电树枝性能和交、直流击穿强度的影响,探究电压稳定剂的抗迁出性以及电压稳定剂对压力下EPDM直流击穿强度和沿面击穿电压的影响。结果表明,4种电压稳定剂均能提高EPDM的交流电树枝起始电压,并抑制电树枝生长;电压稳定剂对EPDM交流击穿强度改善的作用有限,但均能提高EPDM的直流击穿强度;该文所选电压稳定剂能参与交联反应并接枝在EPDM大分子上,因此具有良好的抗迁出性;随着外施压力的增大,EPDM直流击穿强度先增大、后减小,且高压力下电压稳定剂作用效果有所削弱。沿面击穿实验结果表明,4种电压稳定剂对于EPDM表面击穿电压有提高作用,且对EPDM-交联聚乙烯绝缘界面击穿电压的改善效果更加显著。

面向国家"碳达峰"与"碳中和"的"双碳"战略需求,移动通信与网络需要在满足不断增长的业务需求前提下大幅度降低全网能耗,因此需要研究使用更少的能量传递更多信息(SMILE, send more information bits with less energy)的理论与技术。为了应对该挑战,仅靠无线传输技术的改进和硬件实现水平的提高是远远不够的,需要从系统和网络的角度探索能量的高效利用机理与方法。从能量的"节流"和"开源"2个维度展开,并针对日益增长的计算能耗给出解决方案。具体地,通过引入超蜂窝网络架构实现网络的柔性覆盖与弹性接入,使业务基站和边缘服务器在业务量较低时可以进入休眠状态,减少能量的浪费(即"节流")。同时,大量引入可再生绿色能源(即"开源"),通过能量流与信息流的智能适配,大幅降低电网的能耗。进一步地,通过网络功能虚拟化、通信与计算资源的高能效协同,以及移动智能体的分布式计算与协同等手段,实现绿色计算与人工智能算法。

纳税人基于信赖税务行政机关的公权力行为而遭受的信赖利益损害应充分予以保护与救济。但是在适用该制度时,不能仅以违反法律强制性规定或损害国家利益、社会公共利益为由予以阻却,而应依据存在可供纳税人产生信赖的公权力行为、纳税人做出信赖表现、信赖具备正当性和因该信赖而产生损失等四项要件予以综合判断。为有效填补受害人的损害以及避免受害人因信赖利益损害补偿获取额外的利益,应采取“损失补偿”救济方式且根据其受损害类型和加害人对于信赖利益损害发生的主观过错程度来判断受害人的损害赔偿范围。

Due to the increasing need for massive data analysis and machine learning model training at the network edge, as well as the rising concerns about data privacy, a new distrib?uted training framework called federated learning (FL) has emerged and attracted much at?tention from both academia and industry. In FL, participating devices iteratively update the local models based on their own data and contribute to the global training by uploading mod?el updates until the training converges. Therefore, the computation capabilities of mobile de?vices can be utilized and the data privacy can be preserved. However, deploying FL in re?source-constrained wireless networks encounters several challenges, including the limited energy of mobile devices, weak onboard computing capability, and scarce wireless band?width. To address these challenges, recent solutions have been proposed to maximize the convergence rate or minimize the energy consumption under heterogeneous constraints. In this overview, we first introduce the backgrounds and fundamentals of FL. Then, the key challenges in deploying FL in wireless networks are discussed, and several existing solu?tions are reviewed. Finally, we highlight the open issues and future research directions in FL scheduling.
