散打拳法连击技术的宏观分析     

李扬 《平原大学学报》2007,24(6):125-127

从理论上讲,任意两种或多种拳法之间都可以组合。受传统武术思想的影响,在散打运动员的训练与竞技实践中,拳法连击未能得到人们足够的重视。拳法组合连击技术的进攻形式是非常繁多的,且具有腿法所达不到的高度机动性,灵活快速的攻击是拳法组合连击技术的重要特点之一。  相似文献   

Design considerations for series hybrid active power filter     

Chen Guo-zhu  Lu Zheng-yu  Qian Zhao-ming 《浙江大学学报(A卷英文版)》2001,2(3):313-317

Some important factors for designing a series hybrid active power filter (SHAPF) are presented in this paper for the case when the load is varied in a wide range and/or the source voltage is seriously distorted. Special design of passive filters, adaptive control of parameter and multi variant control are discussed in detail. The filter is stable, has good performance, and causes small capacitive reactive current. The simulation and experimental results accorded with the theoretical analysis results.

From data source to co-researchers? Tracing the shift from ‘student voice’ to student–teacher partnerships in Educational Action Research     

Susan Groundwater-Smith 《Educational Action Research》2016,24(2):159-176

This article provides a review of the concept of student voice as it has been represented in Educational Action Research from the 1990s to the present day. Contextualised within an exploration of the challenges posed by educational action research that incorporates student voice in the current age of accountability as reflected and understood in academia, we explore issues of power and authority, issues of process and issues of ownership as they emerge in the literature. We note ways in which these challenges are manifest in primary and secondary schooling and in tertiary education. Finally, we survey some recent representations of student voice in Educational Action Research, observing something of a shift from earlier conceptualisations of students as a ‘data source’ to a more active involvement as co-researchers and joint constructors of knowledge, progressing toward more active student–teacher partnerships.  相似文献
