Black Fiction surveys a wide variety of novels, bringing to our attention in the process some fascinating and (75) little-known works like James Weldon Johnson’s Autobiography of an Ex- Colored Man. 《黑人小说》考察了极为广泛的一系列小说,在此过程中让我们注意到了某些引人入胜但却鲜为人知的作品,如詹姆斯·韦尔登·约翰逊(Jameseldon Johnson)的《一个曾经是有色人的自传》(Autobiography of an Ex-ColoredMan)。 Although these molecules (5) allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through, they absorb some of the longer-wavelength, infrared emissions radiated from the (10) Earth’s surface, radiation that would otherwise be transmitted back into space. 虽然这些分子允许可见波长(visible wavelength)的辐射——阳光的绝大部分能量就汇集于此——不受阻挡地穿透,但它们却会吸收某些较长波长(longer-wavelength),亦即从地球表面辐射出的红外发射(infrared cmission),这种辐射若不是二氧化碳的缘故就会被重新输送回太空。 The role those anthropologists (5) ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints—ways of feeling, thinking, and acting that "come naturally" in archetypal situations (10) in any culture. 这些人类学家所归诸于生物进化的作用,不是规定人类行为的种种细节,而是将各种限制强加于人类——即在任何文化的典型情景中都会“自然表露”的情感、思维、以及行动方式。 A low number of algal cells in the presence (10) of a high number of grazers suggested, but did not prove, that the grazers had removed most of the algae. 在存在大量食草动物的同时却只有少量的水藻花粉囊,这暗示出——但没能证明——食草动物已吞噬了大部分水藻。 Studies by Hargrave and Geen estimated natural community graz- ing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community (55) grazing rates for field conditions using the known population density of grazers. 由哈格雷夫(Hargrave)和吉恩(Geen)所进行的研究,对自然条件下的群落食草比例进行了估计,其手段是通过测量出实验室内单独的浮游动物种类的结食比例,然后利用已知的食草动物种群密度,计算出实地状况下的群落食草比例。 In the periods of peak zooplankton abundance, that is, in the late spring and in the summer, Haney recorded maximum daily com- (70) munity grazing rates, for nutrient-poor lakes and bog lakes, respectively, of 6.6 percent and 114 percent of daily phytoplankton production. 在浮游动物数量激增的高峰期,亦即在春季后期以及夏季,哈尼记录了最大程度上的每日群落食草比率,对于营养物不充足的湖和沼泽湖而言,分别为每日浮游植物繁殖量的6.6%和114%。 The hydrologic cycle, a major topic in this science, is the complete cycle of phenomena through which water passes, beginning as atmospheric water vapor, (10) passing into liquid and solid form as precipitation, thence along and into the ground surface, and finally again returning to the form of atmospheric water vapor by means of evaporation and (15) transpiration. 水文循环(hydrologic cycle),作为该学科中的一个主要课题,指的是水所经过的诸现象的整个循环过程,开始时是作 为大气中的水蒸气,转而作为雨、雪、露、雹一类的降水量经过液体和固体形态,由此而沿着地层表面分布或进入地层表面,最终通过蒸发和散发作用再度回复到大气水蒸气的形态。 |
