赢得卓越——体验企业教练技术

沉思:时代需要什么样的企业? 稍稍留意一下改革开放几十年中国企业的发展历程,不难发现这样一条规律:抛开国有企业、集体企业不谈,八十年代是谁敢办企业,谁就能够挣钱、发财,不管其文化水平、社会地位、人生阅历,也不管是城里人还是农村人;九十年代做企业就不那么容易了,只要投资就能赚钱已成为不可能,这个时期所能生     

论历史教学的课堂语言要求

语言表达是教师的一项基本功。历史教学中教师的课堂语言,必须讲求科学性并做到形象生动,还要感情充沛,语言简练、干净、明确。     

语言生成过程中的艺术品性--对卡西尔语言生成论的一种解读

构成语言的基本单位之一是名称，名称最早产生于直觉的聚合。在人类的神话阶段，人们对神的崇拜实质上是对神的名称的崇拜，因为各种神灵的本质只是一种只有能指而没有所指的虚构。早期人类意识中的隐喻思维对名称的产生起了关键的作用。所以，语言生成的初始过程不是一个逻辑化的过程，而是一个诗性思维的过程。     

比较教育研究的基本范式述评

本文根据历史线索对比较教育研究领域中的三种范式：科学主义的研究范式、批判理论的研究范式和解释学的研究范式，进行了大致的厘定和评价，试图展示该领域理论形态和研究策略的整体景观。同时，就各自理论话语所处的特定语境作简单的分析，并倡导各自间不应是相互对峙与攻讦，而是要彼此间抱宽容和理解态度，不是苛求于整合而是要寻求互补。     

千古谁堪伯仲间--词学批评史中的苏辛词比较论

苏辛词的关系是词学批评史中一个历久弥新的重要论题，自南宋进入词学批评视野始至近代约七百余年的接受历程中，涉及到苏、辛词体派上的承继关系、风格意境异同、词史地位诸方面；由于时代社会背景的不同，词学观念、理论宗尚和审美理想的差异，在不同的词学批评者和词派那里皆代有不同。与这一“接受之链”的嬗递过程相应，词学批评史的若干建构特征亦由此得以呈现。     

Header error control schemes for coping with upstream channel noise in the HFC network

The Hybrid Fiber-Coax (HFC) network is being paid close attention to in recent years as a bi-directional broadband access network. To achieve seamless connection with the backbone network, and Asynchronous Transfer Mode (ATM) Network Network Interface (NNI) cell format is used as the basic transmission packet unit in the HFC system. As the transmission condition of the HFC system’s upstream channel is bad, two improved header error control (HEC) schemes, i. e. the improved HEC and the cell interleaving technique, are employed to guarantee the packet integrity. Theoretical analysis of the results showed that the improved HEC and the cell interleaving technique are applicable to isolated random errors and burst errors, respectively.     

美国高校学术科研信息公开的原则、标准及路径

科学研究是高校自治中的重要内容,也是自治程度最高的领域。同政府信息公开相比,学术科研信息适用推定公开原则的范围较窄,其是否公开涉及的因素更多,公开范围的确定和划分更加复杂。从学术科研信息公开范围来看,美国大学信息公开制度主要从信息公开时间节点、信息种类、所涉利益的轻重缓急等多个维度出发,制定了一套易于实施操作的分类划分标准,很好的处理了学术自治与信息公开之间的矛盾,在保证信息公开的同时维护了相关利益者的权益。通过案例分析,对美国学术科研信息公开制度进行了深入探讨,对信息分类方法、标准和原则等进行了讨论,为我国学术科研信息公开提供有益经验。     

Event triggering power sharing control for AC/DC microgrids based on P -F droop curve method

The power sharing of AC/DC micro-grids is researched in this paper. The proposed strategy mainly include two parts: the primary power event triggering control with secondary control and an adaptive quasi sliding mode voltage control in inner-loop. Firstly, a event triggering power sharing control (ETPSC) based on $P?F$ droop curve is developed to regulate the voltage and frequency of AC and voltage of DC with the aim of the proportional power sharing between AC and DC micro-grids. The triggered threshold of ETPSC can be chosen to decide the transmitted power between AC and DC micro-grids. When the difference power between AC and DC micro-grids is less than the triggered threshold of power flow, there is no power sharing between AC and DC micro-grids, which can less the number of switching the power flow direction and the transmitted line power loss. The ETPSC has a great robust for the disturbances of load and improve the stability of the system. An adaptive quasi-sliding-mode control,which is implemented easily and flexibly with small computational burden and only based on input/output (I/O) measurement data but not the model any more, is used to control voltage in inner-loop. The effectiveness of the proposed control schemes is demonstrated by some numerical simulations and experimental results.
