教育的天平——关于生存教育与地位教育     

谢石 《山东教育学院学报》2007,22(3):16-18

随着社会的发展,人们对教育的重视已经到了前所未有的高度。本文分析了教育不平等中的生存教育与地位教育这对相互之间充满矛盾的教育方式,得出了这两类教育与阶级藩篱之间的关系。并以此为依据,分析了我国的教育发展与其中存在的不平等。  相似文献

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     

谢冬冰 《南京师范大学文学院学报》2004,(1):25-31

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。  相似文献   

全球化对高校德育的挑战及对策     

谢振荣 《台州学院学报》2003,25(5):71-73

在全球化及中西文化价值观的激烈冲突的背景下,高校德育对象的价值观发生了重大变化,这给高校德育工作提出了挑战。德育教师要树立教育国际化观念;高校德育以弘扬中华优秀文化为己任;推进德育创新,把德育的视野从智力领域扩展到非智力领域;运用现代科学技术,进行德育手段的创新。  相似文献   

比较教育研究的基本范式述评   总被引：5，自引：0，他引：5  

谢安邦  阎光才 《华东师范大学学报(教育科学版)》2001,19(3):45-52

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。  相似文献   

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

Chen Hui-fang  Xie Lei  Qiu Pei-liang 《浙江大学学报(A卷英文版)》2001,2(1):51-55

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.  相似文献

Novel high torque bearingless two-sided rotary ultrasonic motor   总被引：3，自引：0，他引：3  

LI Xia CHEN Wei-shan XIE Tao LIU Jun-kao 《浙江大学学报(A卷英文版)》2007,8(5):786-792

Applications are limited at present because the currently available ultrasonic motors (USMs) do not provide suffi-ciently high torque and power. The conventional travelling-wave USM needs the bearing to support, which required lubricant. To solve the above problem, a bearingless travelling-wave USM is designed. First, a novel structure of the two-sided USM consisting of a two-sided teeth stator and two disk-type rotors is designed. And the excitation principle of the two-sided travelling-wave USM is analyzed. Then, using ANSYS software, we set up the model of the stator to predict the excitation frequency and modal response of the stator. The shape of the vibration mode was obtained. Last, the load characteristics of the USM are measured using ex-perimental method. The maximum stall torque and the no-load speed were obtained. The results showed that the characteristics of the two-sided USM are better than those of the conventional one-sided USM.  相似文献   

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

Dazhong Ma  Qiuye Sun  Xiangpeng Xie  Xiaoyu Li 《Journal of The Franklin Institute》2019,356(3):1225-1246

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.  相似文献
