普通高校田径运动员力量训练的研究   总被引：2，自引：0，他引：2  

刘咸祥  姚素云 《四川体育科学》2006,(3):135-138

训练对象的不同,力量训练的方法与手段等存在明显差异。普通高校田径运动员力量基础的薄弱性、力量训练的短期效益性,以及训练计划的频繁变更性等决定了其力量训练不能机械地照搬专业队的训练模式和训练方法。本文主要运用文献资料法,对普通高校田径运动员力量训练的特点进行深入地分析,并在此基础上提出了普通高校田径运动员力量训练必须遵循的六条原则和四种训练方法,以供广大教练员参考之用。  相似文献

Out of Sight, (Not Yet) Out of Mind: The Impact of Tie Strength on Direct Interaction and Social Surveillance Among Geographically Close and Long-Distance Facebook Friends     

Kevin Koban  Sophie Krüger 《Communication Research Reports》2018,35(1):74-84

Social networking sites are considered a valuable resource to maintain existing friendships even over considerable distances. The present study emphasizes tie strength as a crucial determinant for the use of interactive and passive features among 302 active Facebook users and friends of different relational closeness (close friends vs. casual friends vs. acquaintances) as well as a moderator for the impact of physical distance. As expected, tie strength affected direct interaction linearly, whereas social surveillance followed a quadratic trend. Furthermore, moderation analyses revealed less frequent direct interaction between close friends and stronger surveillance of casual friends’ profiles as physical distance increases. These results indicate different functions in relationship maintenance for both behaviors as direct interaction aims at nurturing current relationships, while surveillance serves as a catalyst for promising future communications. As a consequence, physical distance influences direct interaction adversely due to emerging constraints but also contains informational value encouraging information-seeking behaviors.  相似文献   

关于申论考试中几个问题的分析     

洪威雷  宋俊丽  王汉斌 《广播电视大学学报》2004,(2):47-49,71

申论考试是我国公开、公正、公平选拔公务员制度的一种创新,为造就一支高素质、专业化的国家公务员队伍提供了一个规范化的竞争平台。中沦考试的主要特点是“试卷编排的程序性”、“答题过程的程序性”、“能力测试的综合性”、“考试的限制性”。申论考试是一种全新的考试,应掌握一定的阅读方法,紧扣方案的针对性,做到看清“虚拟身份”,明确文体要求,突出可行性。论述写作力争做到拟题脱俗巧点睛,以小见大高立意,说理论道重分析,言活语实可触摸,有的放矢关痛痒．辩证论述防片面．  相似文献   

The effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion     

Jane L. Down 《文物保护研究》2016,61(1):26-45

This paper examines the effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion adhesive upon aging. Eighteen common modifiers were added to a well-characterized vinyl acetate/ethylene copolymer dispersion (Dur-O-Set^® E-150) in known concentrations and dry-film samples were subjected to 16–17 years of dark aging and seven to eight years of light aging. Yellowing, pH, gloss, swelling, cohesive strength, and flexibility were monitored for changes upon aging. Generally, the neat Dur-O-Set^® E-150 (no additives) was found to become acidic on aging, but was fairly resistant to yellowing. It also swelled substantially in toluene, was of high gloss, medium strength, and flexible, and remained so on aging. No modifier was found to improve these properties. Various solvents, wetting agents, and thickeners did not alter the properties by much, while plasticizers, freeze-thaw stabilizer, glycerin, and certain fillers had a more negative effect.  相似文献   

A four spiral slots microstrip patch antenna for radiotelemetry capsules based on FDTD     

HUANG Biao YAN Guo-zheng LI Qian-ru 《浙江大学学报(A卷英文版)》2007,8(10):1560-1567

Antenna is very crucial to radiotelemetry capsules which can measure the physiological parameters of the gastroin- testinal (GI) tract. The objective of this paper is to design a novel spiral slots microstrip patch antenna for the radiotelemetry capsules communicating with external recorder at 915 MHz located in ISM (Industry, Science, and Medical) bands. The microstrip patch antenna is designed and evaluated using the finite-difference time-domain (FDTD) method. Return loss characteristics and the effect of the human body on resonant frequency are analyzed, and the performances of radiation patterns at different positions of the human alimentary tract are also estimated. Finally, specific absorption rate (SAR) computations are performed, and the peak 1-g and 10-g SAR values are calculated. According to the peak SAR values, the maximum delivered power for the designed antenna was found so that the SAR values of the antenna satisfy the ANSI (American National Standards Institute) limitations.  相似文献
