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

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。     

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.     

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.     

浅析西藏环境保护的发展思路

西藏由于人烟稀少，自然资源极其丰富，人类活动对生态环境的影响轻微，自然资源的开发程度和城市化水平低，工业规模小，环境污染相对较轻，主要江河、湖泊的水质均能达标，至今未出现过酸雨和放射性污染，自然环境基本处于原生状态，是目前世界上空气质量保持较好的地区之一。本文根据西藏环境保护工作的有利形势和不利形势。谈谈在新世纪初西藏环境保护的发展思路。
