近50年晋城地区霜冻变化特征分析
Analysis of the Feature of the Frost Events Change in Jincheng Region in Recent 50 Years
 [PDF]

海霞, 鹏娟, 赵慧琴, 张建红
Climate Change Research Letters (CCRL) , 2014, DOI: 10.12677/CCRL.2014.31004
Abstract:  利用气候分析法分析了晋城地区1961~2010年霜冻的气候变化特征;利用异常霜冻指标,分析了霜冻的异常发生情况。结果表明:晋城地区初霜日平均值为1015日,时间序列绝对变率为8.27 d,线性倾向率为1.125 d/10a,有推后的趋势,初霜日变化年际差异大,有很大的预报难度;终霜日平均值为47日,时间序列绝对变率为7.25 d,线性倾向率为0.257 d/10a,有弱的推后趋势,终霜日变化年际差异较大,有预报难度;而无霜期平均值为189 d,绝对变率为8.09 d,线性倾向率为1.32 d/10a,无霜期有较明显的增加趋势。异常霜冻年份很少,偏早初霜冻对于部分年份的秋粮作物可能会产生较大影响;高寒地区春播幼苗主要会受到特晚终霜冻的影响;冬小麦遭受终霜冻危害的频率平均为6年一遇,拔节后5天内发生频率较大。
  Climatological statistics method was used to analyze climate characteristics of frost in Jincheng region during 1961-2010, and abnormal frost index was used to analyze abnormal occurrence of frost. The results indicated that the average value of the first frost day was October 15, the absolute variability of time series was 8.27 days, and the linear trend was 1.125 d/10a. Thus the first frost day showed the delaying trend, and the first frost day has a big annual difference making forecasting difficult. For the latest frost days, the average value was April 7, the absolute variability of time series was 7.25 days, and the linear trend was 0.257 d/10a. Thus the latest

Abstract:

《大学的使命》是一部具有强烈批判和改革精神的经典著作,它充分展示了奥尔特加?加塞特高等教育思想的创造性和预见性。本文基于对《大学的使命》的理解和分析,从大学职能的论述、学生中心地位的强调、大学的批判精神和大众教育思想四方面来重新解读奥尔特加的大学理念。
“Mission of the University” is a classic works full of the spirits of critique and reform, which fully demonstrates the creativity and foresight of Ortega Y. Gasset’ creative ideas of higher education. This article reinterprets Ortega’ ideas of university from the functions of universities, emphasis on student center, critical spirit of universities and mass education based on understanding and analysis of “Mission of the University”.

Advances in Education (AE) , 2011, DOI: 10.12677/ae.2011.13019
Abstract:

自20世纪80年代,学习结果作为保证高等教育质量的重要准则引起了一些国家的关注。时至今日,学习结果仍然是一个新课题并被不断的完善。其中欧盟和美国是在学习结果的制定和应用方面做得最好的国家,它们都形成了自己独特的经验和模式。但是作为两个国情不同的地区和国家,它们在学习结果制定的背景、学习结果的界定以及学习结果的应用等方面除了共性外,还有着各自的特点,对二者进行比较研究对于我们进一步理解学习结果具有非常重要的意义。
Learning outcomes, as important guidelines to ensure quality of higher education, has raised some national concerns since 80 years of the 20th century. Today, learning outcomes is still a new subject and is constantly improving. The EU and the United States in the development and application of learning outcomes is doing their best, and they have formed their own unique experiences and models. But as two region and country with different conditions, they have their characteristics in the backgrounds definitions development and application of learning outcomes besides of common ones. Doing comparative study on the both for fur-thering our understanding of learning outcomes is very meaningful.

World Literature Studies (WLS) , 2013, DOI: 10.12677/WLS.2013.12006
Abstract:

目前国内外对于曼斯菲尔德短篇小说所体现的现代主义特征已有不少研究,但是她的不同于同时代男性现代主义作家的独特之处往往被忽略,至今尚缺乏充分的阐释和分析。本文试图弥补这方面的欠缺,将从异化人精神世界的散文诗和生活的细枝末节和瞬间印象两个方面对曼斯菲尔德短篇小说所体现的女性版本现代主义进行深入的探讨,力图从一个新的视角加深对曼斯菲尔德短篇小说的理解和阐释。
Until now, there is much study on the features of modernism that reflected in Mansfield’s short stories. However, her unique characteristic of modernism which is different from the male writers of her time is always neglected, and there have been no due and convincing interpretation of it up to now. This paper in- tends to make a thorough analysis of the female version of modernism in Mansfield’s short stories and tries to interpret from two new perspectives: 1) lyric poetry of alienated people’s spiritual world; 2) triviality and transient impressions of life.

Abstract:

目前国内外对于曼斯菲尔德短篇小说所体现的现代主义特征已有不少研究,但是对于她作品中所体现出的象征手法至今尚缺乏系统而充分的阐释和分析。该文试图弥补这方面的欠缺,将从物品、自然景物及场景、小说标题和人物的动作和行为等四个方面对曼斯菲尔德短篇小说所体现的象征主义进行深入的探讨,力图从一个新的视角加深对曼斯菲尔德短篇小说的理解和阐释。
Until now, there is much study on the features of modernism reflected in Mansfield’s short stories. However, an all-round study on her characteristic of symbolism is always neglected, and there has been no due and convincing interpretation of it up to now. This paper intends to make a thorough analysis of her unique symbolism in Mansfield’s short stories and tries to interpret from four perspectives: items, natural scenery and setting, title of the novel and the character's actions and behavior.

应用生态学报 , 2011,
Abstract: 在华北平原黑龙港流域对冬小麦实行3种灌溉模式,研究了不同灌溉模式对冬小麦-夏玉米产量、耗水特性和水分利用效率的影响.结果表明:浇底墒水+拔节水处理(w2,75mm+90mm)和浇底墒水+拔节水+灌浆水处理(w3,75mm+90mm+60mm)周年总产量均显著高于只浇底墒水处理(w1,75mm),增幅分别为8.7%和12.5%.冬小麦全生育期对土壤水的消耗随灌溉量的增加而减少,夏玉米季总耗水量随冬小麦季灌溉量的增加而增加.w2处理冬小麦水分利用效(wue)比w3处理高11.1%,而其夏玉米水分利用效率(wue)与w3处理差异不显著.w2和w1处理的周年水分利用效率(wuet)分别为21.28和21.60kg·mm-1·hm-2,比w3处理分别高7.8%和9.4%.综合周年产量、耗水量和水分利用效率,w2是较好的节水丰产灌溉模式.
