西双版纳雨季次生林林窗定居种冠面温度特征

利用西双版纳雨季（7月）次生林林窗叶表温的观测资料，探讨了林窗内定居种冠层温度的时空变化特征。结果表明，因林窗不同区所接受太阳辐射的差异，加之林缘热力效应的综合作用，使得林窗定居种冠面在不同时段其最大热力作用区域是各异的；林窗各测点与中央的叶表温差区域分异显，特别是中午的分异最为明显。植株叶表温度与气温平衡在25.8℃附近，但因受日照、林缘树木的综合影响，不同方位达平衡的时刻不同：林窗南侧边缘叶表温与气温整天基本处于平衡状态，下午6时后受阴天和树冠荫蔽的影响，各测点叶表温与气温均处于平衡状态；在晴好天气状况及不受荫蔽状况下，叶表温高于气温，波动范围为0－3℃；15时雨后初晴，叶面蒸发耗热，叶表温低于气温。这种“峰值动态位移现象”可能会影响不同时期物种的入侵、定居、繁殖，进而影响林窗物种的组成。     

从柳永《雨霖铃》看宋代的送别风俗

通过对柳永的《雨霖铃》文本分析,可知宋代饯别、赠言、摇装等送别风俗的内容,反映出宋代送别时间、地点、方式比较固定统一的文化现象;透露出人们重情重义、喜聚不喜散、渴求平安、安土重迁的文化心态;刻画出古人对外出远行的审慎态度、对异地文化的失落感以及厌倦羁旅漂泊生活的苦闷情绪。这些送别文化习俗对当今送别文化产生了深远影响。     

论《雷雨》的俄狄浦斯情结

将中国现代文学中表现俄狄浦斯情结的《公墓》、《内疚》、《女娲氏之遗孽》、《叶罗提之墓》、《姊嫁之花》和《雷雨》进行比较后认为:前几篇小说限于对心理分析理论的形象化图解,未能充分展开俄狄浦斯情结的内涵;《雷雨》由于设置了周朴园专制冷酷的形象为背景、表现周萍和繁漪的乱伦关系以及周萍对四凤的爱而将这一情结表现得惊心动魄。《雷雨》成功表现俄狄浦斯情结的原因在于:西方戏剧的命运观和曹禺对命运的思考的相互融合、曹禺强烈的俄狄浦斯情结及作为艺术家对集体无意识的幻想创作。

On the genesis of the soil mantle of the region of Manaus,Central Amazonia,Brazil

Summary The dynamics of the forest to the north of Manaus is tightly linked to that of the soil. The latosol that covers the plateau, which supports a dense forest, consists from top to bottom of: (a) a brown, clayey organic horizon (0.3 m), (b) a yellow horizon, very rich in clay but permeable (from 0.3 to 4 m), (c) a nodular horizon rich in Al and Fe oxides (from 4 to 9 m), and (d) a horizon which still preserves the sedimentary structures of the parent sandstone, where quartz is intensely dissolved and kaolinite crystallizes in pores. In perfectly flat areas, the clay of the organic horizon is destroyed by acidocomplexolysis, and the dissolved Al is transported vertically by the drainage water. A part of this Al is used to make the gibbsite nodules of horizon (c), and the rest is used to make kaolinite in horizon (d). Because aluminum is thus conserved within any vertical prism, the rate of destruction of horizon (a) is equivalent to the rate of advance of the kaolinization zone into the sediment: the latosol is said to be in equilibrium, the surface remains perfectly flat as it slowly sinks, the quantity of kaolinite increases with time, and the silica released by quartz dissolution in the whole profile is exported by drainage water to the water table. In contrast, near drainage axes, however small initially, the drainage becomes inclined toward the axis. Part of the Al released by acidocomplexolysis of horizon (a) is now exported to rivers, and Al is no longer conserved within any given prism. The rate of advance of the kaolinization zone (d) into the sediment now becomes less than the rate of destruction of horizon (a) and the surface sinks faster than that of the surrounding plateau. After this differential podzolization has gone on long enough, it creates a network of geochemical valleys characterized by convex slopes and bounded by sandy soils (campinas). The vegetation becomes sparser and sparser. At the end, only some bushes and lichens survive on the white sand.Acknowledgments. The authors are indebted to Dr E.

“先行结构”与理解的作用

理解指读者对文学作品的理解和解释,＂先行结构＂指制约着读者自己对文学作品的理解和解释的＂前理解＂,向新的理解和解释开放的可能性可以使读者投入思考,从而赋与作品深刻丰富的内涵。海明威的短篇小说《雨里的猫》可以从这两个方面入手解读与阐释,其中的空白点,需要读者在阅读过程中填充。     

论陈恭尹诗中的“雨”意象

诗人陈恭尹对“雨”意象情有独钟。他在诗中刻意营构多姿多彩的“雨”意象，可谓到了登峰造极的地步。陈恭尹笔下的“雨”，既有冷暖之分，又有粗细疏密、新旧、动静之别。诗人赋予“雨”以人格化，在情景的交融中使读者获得美感。

从《雨中的猫》看海明威的生态女性意识

生态女性主义是妇女解放运动和环境保护运动相结合的产物,它追求整体和谐与生命解放,反对压迫。生态女性主义的理想是建立一个生态的、可持续的社会。在这个社会中,人类与自然、男性与女性平等相处、相互依存、和谐发展、共同繁荣。本文旨在运用生态女性主义的观点分析海明威在《雨中的猫》中所体现的生态女性意识。
