湖北省大学生溺水高危行为调查研究

运用问卷调查等方法揭示湖北省大学生溺水高危行为和水域安全教育现状。结果发现:湖北省大学生溺水经历普遍、溺水高危行为常态化、游泳教育现状堪忧,建议科学构建大学生水域安全教育模式、配套教育资源;完善教育法规、补强基础设施、落实大学生游泳教学;构建学校-社会-家庭三维联动的预警与防护体系。     

全长cDNA文库构建技术在运动遗传资源利用中的潜在价值与展望

随着人类基因组计划(human genome project,HGP)的完成,人们对当前自身遗传信息有了新的认识.无奈不同条件下基因表达水平变化各有差异,从而造成不同个体生理表型与功能上的迥然不同.随着测序技术的快速发展,构建高质量的全长cDNA文库成为当前研究者们研究转录组学的重要技术手段之一.通过查阅文献发现目前有四种全长cDNA文库构建技术已趋于成熟,应用更为普遍,但在运动科学领域至今却无人提及.详述近年来几种技术现已成熟的全长cDNA文库构建方法及特点,并对其应用性进行概述,推测其在运动领域同样存在潜在的应用价值,若以此法对运动员遗传资源加以利用,预计将会运动科学的发展发挥重要影响.     

An extended version of the theory of planned behaviour: the role of self-efficacy and past behaviour in predicting the physical activity of Chinese adolescents

This study aimed to use an extended theory of planned behaviour (TPB), which incorporated additional self-efficacy and past behaviour, to predict the intention to engage in moderate-to-vigorous physical activity (MVPA) and the MVPA level of Chinese adolescents. Questionnaires that focused on MVPA, attitude, subjective norm, perceived behavioural control (PBC), self-efficacy and past behaviour related to the MVPA engagement were administered to a sample of 488 young people. Multiple regression analyses provided moderate support for TPB. Three TPB constructs predicted 28.7% of the variance in intentions to engage in MVPA, and that PBC, but not intention, explained 3.4% of the variance in MVPA. Self-efficacy significantly affected intention and behaviour over and above the influence of TPB. Past behaviour had a small but significant improvement in the prediction of intention, but no improvement in the prediction of MVPA. Based on the results, interventions should target adolescent self-efficacy and PBC in physical activity participation.

电力变压器离线局部放电测量试验中的容升现象分析

Partial discharge test on a transformer is carried out according to the items in IEC 60.During the test,unproved measuring system is calibrated by proved system at a voltage no less than 50% the rated testing voltage.The result is then extrapolated linearly,leading to an error related to the distribution of stray capacitance,which varies with the testing frequency,especially to large transformers.In this paper a factor,named the capacitive rise fact,is introduced to assess the rise.The factor can be adjusted to some extent by changing the reactance that is connected to the LV side of the testing circuit to lower the capacity of the power source.However,the factor changes when the voltage divider on the high voltage side is removed after the voltage ratio has been calculated,and a great error is resulted under unfavorable conditions.     

石油工程专业探索性实验提升大学生创新能力的意义

国内石油工程专业的本科生实验以传统验证性实验为主,缺少探索性实验教学。验证性实验教学偏重实验结果,是一种再现式的教学模式,不能充分体现实验探索未知的意义,造成大学生缺乏应有的创造能力,思维呆板,认识问题的方法单一,跟不上石油工程学科培育人才的发展要求。探索性实验,重在对未知的探索,有利于激发学生的好奇心,提高学生的主观能动性,克服其思维僵化的状态、培养思维灵活性,对提升大学生创新能力有着十分重要的意义。
