加强沟通协调 扎实我国图书馆联盟建设基础

比较分析历史和现状，指出我国图书馆联盟发展水平较低主要在于联盟内部沟通协调这个环节有问题，导致联盟基础不实。针对问题提出扎实基础的对策和方法。     

The role of reduced frequency of knowledge of results during constant practice

Two experiments were conducted to further examine the effects of reduced knowledge of results (KR) frequency on the learning of motor skills during constant practice. In Experiment 1, participants in five KR conditions (100% KR, 50% KR-fade, 50% KR-reverse fade, 50% KR-alternative, and 50% KR-random) practiced a movement timing task. In Experiment 2, participants in two KR conditions (100% KR and 50% KR-fade) practiced a waveform reproduction task. The results of both experiments failed to indicate that reduced KR frequency was more effective in promoting learning than the 100% KR conditions. The present study adds to the increasing number of experiments that do not find a benefit of reduced KR frequency on learning in constant practice.

Temporal aspects of the VO2 response at the power output associated with VO2peak in well trained cyclists--implications for interval training prescription

The power output achieved at peak oxygen consumption (VO2peak) and the time this power can be maintained (i.e., Tmax) have been used in prescribing high-intensity interval training. In this context, the present study examined temporal aspects of the VO2 response to exercise at the cycling power that output well trained cyclists achieve their VO2peak (i.e., Pmax). Following a progressive exercise test to determine VO2peak, 43 well trained male cyclists (M age = 25 years, SD = 6; M mass = 75 kg, SD = 7; M VO2peak = 64.8 ml x kg(-1) x min(-1), SD = 5.2) performed two Tmax tests 1 week apart. Values expressed for each participant are means and standard deviations of these two tests. Participants achieved a mean VO2peak during the Tmax test after 176 s (SD = 40; M = 74% of Tmax, SD = 12) and maintained it for 66 s (SD = 39; M = 26% of Tmax, SD = 12). Additionally, they obtained mean 95% of VO2peak after 147 s (SD = 31; M = 62% of Tmax, SD = 8) and maintained it for 95 s (SD = 38; M = 38% of Tmax, SD = 8). These results suggest that 60-70% of Tmax is an appropriate exercise duration for a population of well trained cyclists to attain VO2peak during exercise at Pmax. However, due to intraparticipant variability in the temporal aspects of the VO2 response to exercise at Pmax, future research is needed to examine whether individual high-intensity interval training programs for well trained endurance athletes might best be prescribed according to an athlete's individual VO2 response to exercise at Pmax.

谈写"引言"

绝大多数论文和许多一般性文章的开头都有引言,这好像已经成了一种惯例. 有必要写好引言,因为它是论文或一般性文章的一个组成部分,而且比较重要.说它重要,是因为一般在此处交代本题的目的、性质和范围,述评文献,阐述理论基础,提出问题与假设,说明研究方法、研究结果与论纲,以至为术语定义,交代待研究问题等.这些,实际上是正文的背景材料,用以表明正文所处的环境,读了这一部分才能更好地理解正文.     

我国女子撑竿跳高技术的运动学分析

采用高速摄影与影片解析的方法,对参加１９９６年全国田径锦标赛的６名优秀女子撑竿跳高运动员的技术进行测试,用握杆高度、人体质心速度变化和转动惯量等指标来揭示人—杆系统的运动学规律及其特征。结果表明,孙彩云的“低髋摆体”技术较先进。     

游泳运动员负荷后不同姿势放松游对血乳酸清除的影响

我们通过实验发现 :负荷后采用非主项姿势放松游血乳酸清除速率明显高于主项姿势放松游 (P <0 .0 5 -0 .0 1 ) ,说明负荷与放松之间姿势的转换 ,改变了原负荷肌群的负荷强度 ,并动员了非负荷肌参与活动 ,从而提高了放松活动效果。
