说“休”道“闲”

论述"休"、"闲"二字的原初构形意图,梳理二者意义发展的线索及其与相关字词的意义联系。指出休的字形构意与表示哺乳的乳字有相似之处,人对自然物的依赖犹如小孩对母亲的依赖,是文章的一个亮点。     

Studies of layout of world machine tools industry based on patent analysis

As the foundation of an industrialized country nowadays, machine tools industry is regarded as the engine of industrial development of a country. The developed countries, such as USA, Germany and Japan, have widely deployed the technology of using the patent in order to keep their strength in various fields. This research examins the CNC machine tools industry in the world by using the pa- tent analysis method. It first gives an overview about the world patent application in CNC machine tools industry from 1963 to 2010 and divides the development of the industry into five stages. It also lists the patent application of the world top 20 countries, where the top 5 countries are compared. The patents of the world top 10 companies of machine tools manufacturers are mapped according to the international patent classification （IPC）, and the future trends of world machine tools industry are discussed. Finally conclusions and suggestions are presented.     

Hierarchical power control for OFDM based LTE system

3 GPP LTE has approved uplink intra-cell power control and defined overload indicator （OI） for uplink inter-cell power contrQ1 to mitigate the inter-cell interference （ICI）, respectively. In this pa- per, we propose a hierarchical power control （ HPC ） scheme where intra-eell and inter-cell power controls interact with each other. The inter-cell power control eommand is generated by radio re- source management （RRM） entity according to the ICI-load model together with the current ICI and served load information. This ICI-load model is proposed as a guideline for coordination among cells to enable the system to approach its system specific interference over thermal noise （IoT） work area. Simulation results show that for HPC scheme, the system＇ s IoT is well controlled to fit its pre-de- fined work area and the power efficiency is improved significantly. Our proposed scheme is also ro- bust to different settings of its inter-cell power control period.     

牛顿引力平方反比定律的发现

本文回溯了牛顿早期动力学思想发展的主要线索及其研究的具体过程，深入探究牛顿有关引力平方反比定律发现的认识论根源，指出：牛顿“跨越”离心力定律，应用自己的“（１／２）Ｒ公式”和推广的伽利ｔ２定律，并结合开普勒周期定律，在１６６９年前得到圆轨道上的意向力平方反比关系；牛顿在１６７９年才认识到开普勒面积定律的物理意义，在成文于１６８０年的《论椭圆轨道》原始手稿中解决开普勒命题，即证明椭圆轨道上的引力平方反比定律。     

点电荷的相对性

本文主要讨论在什么条件下可以把实际带电体看作点电荷。目的在于讨论怎样才能更深刻地理解这个概念,并在实验和理论研究中准确地运用它。有些地方在传统看法的基础上有所深化。     

电学史上的五次飞跃

通过分析电学史资料,作者对电学的发展情况在一定程度上进行了概括与总结,指出电学史上的五次重大发现对电学的发展起了巨大的推动作用,在电学史上出现了五次飞跃。文中还简略地介绍了各次发现的基本过程及指导发现者的基本思想。     

重演律的哲学探索

系统阐释"三大重演律"和三个推论,探索了重演律中的偶然和必然、个别和一般、对称与破缺、内环境与外环境等哲学问题,建立重演律方法论,特别是重演方法在模型与模拟、教学法以及文学艺术中的广泛应用的方法,利用重演方法阐明科学、文化、经济加速发展的机制与原理,以及落后国家、落后民族在较短时间赶上先进国家和先进民族的内在机理。     

试论《道路交通安全法》的实施

简述了〈中华人民共和国道路交通安全法〉颁布实施以来,给道路交通安全管理带来的巨大变化,针对新法实施过程中发现的一些问题,提出了进一步改进的措施.     

经济法与社会法中的"社会利益"之辨析——以"法本位"为逻辑起点

传统学说中经济法与社会法均以"社会本位"为基础,但未对其各自视野中的"社会利益"加以区分.对这一问题的讨论应以"法本位"这一法的核心概念为逻辑起点,对一般意义的"社会利益"以及经济法与社会法各自视野下的"社会利益"做出内涵区分,以明确二者在构建和谐社会中的重要使命.
