高职教育发展的理论空间

高职教育的发展目前还存在着一些认识上的误区，而这些正成为影响高职教育健康发展的重要因素。这些影响因素主要有：高职教育的性质、功能和高职院校的定位等。     

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.     

人的生命存在的现实性、超越性与境界问题——兼与陈望衡先生商榷

超越与境界问题是人的生命存在范畴中的问题,精神超越性是审美的根本特质,人只有超然于实践活动的特定视界才可能从其整个生命所全面关涉的世界中“来领会自身”,才可能进入到精神超越乃至审美超越的境界中去;然而,不能忽略了超越性赖以发生的物质性、功利性、个体性以及主客体关系等现实性基础,人的生命境界问题答案的给出,境界论美学的当代性建构,必须奠基于对人的生命存在的现实性、超越性全面深入的考察与体悟之上。     

语符的味象生成机制

人们阅读语符文本会产生辨味审美,就因为语符具有一种生成味象的机制,这种机制源于饮食生活。饮食生活作为味象生成的根基,其通过交感、第二信号系统及联觉通感等多种途径实现语符的味象生成,从而达成辨味审美。     

试论有效教学的生命特征

教学是学校的生命力和灵魂所在,有效教学又是教育工作者执着追求的目标,教学惟有充分体现生命的自由性、完整性、多样性、美丽性以及成长性等重要特征,才是真正意义上的有效教学。     

生命在于运动的理性思考

主要从生命的起源与发展,人类生命的可持续发展与运动的辩证关系等方面,探讨生命在于运动的哲理,从而对运动有更客观的认识.     

Physical activity profiles and selected muscular fitness variables in English schoolchildren: A north–south divide?

The aim of the study was to compare and contrast habitual physical activity (PA) profiles and muscular fitness in schoolchildren from northern and southern regions of England. Data were collected from two secondary schools in the north east (NE) of England. The study procedures followed methods employed by the East of England Healthy Hearts Study in 10–16-year-old boys and girls based in the south east (SE) region of England and data were compared. Habitual physical activity (PAQ-A), vertical jump test, and hand-grip (HG) strength were assessed. We converted raw scores from all assessments to age- and sex-normalised z-scores. We recruited 597 children (58% boys) in the NE and compared findings to 597 age- and sex-matched boys and girls from the SE. Boys in the SE had significantly stronger HG scores, jumped higher, were more powerful (mean peak power: 2131?W vs. 1782?W; P?P?P?相似文献   

君子和而不同——谈苏轼兄弟的异质异貌

苏轼兄弟手足情深,成为千古称美的文学佳话。然而,这种深厚的情谊并不是以二人的种种相同特质为表现形式的,在他们性情气质、文学个性、生活态度与生活方式等方面,实际存在着最重要的异质异貌特征,恰是这些“和而不同”的独特风貌,使他们在现实生活与文学生涯中,取得了适合自身个性发展和他人无法取代的成就。
