106. The converse observation, of the absence of grazers in areas of high phytoPlanktonconcentration, led Hardy to propose his principle of animal exclusion , which hypothesized that phytoplankton produced a repellent that excluded grazers from regions of high phytoplankton concentration.
107. Although these molecules allow radiation at visible at wave lengths, where most of the energy of sunlight is concentrated, to pass through, they absorb some of the longer-wavelength, infrared emission radiated from the Earths surface, radiation that would otherwise be transmitted back into space.
108. In addition, the style of some Black novels, like Jean Toomers Cane, verges on expressionism or surrealism, does this technique provide a counter point to the prevalent theme that portrays the fate against which Black heroes are pitted, a theme usually conveyed by more naturalistic modes of expression?
109. Roseenblatts thematic analysis permits considerable objectivity; he even explicitly states that it is not his intention to judge the merit of the various worksyet his reluctance seems misplaced, especially since an attempt to appraise might have led to interesting results.
110. Thus, for instance, it may come as a shock to mathematicians to learn that the Schrodinger equation for the hydrogen atom is not a literally correct description of this atom, but only an approximation to a somewhat more correct equation taking account of spin, magnetic dipole , and relatiristic effects, and that this corrected equation is itself only an imperfect approximation to an infinite set of quantum field theoretical equations.
106、相反的观察,即在浮游植物群落高度集中的地方缺乏食草动物的现象,使哈笛提出了他的动物排除理论,该理论假设浮游植物群落能产生一种驱虫剂赶走在浮游植物高度集中区域内的食草动物。

108、此外,一些黑人小说的风格,像Jean Toomer的Cane,就接近于表现主义或者超现实主义,这种巧合是否给流行描述黑人主人公与命运对抗的主题提供了一个反衬点,或者经常被更加自然的表达模式所传达的主题?
109、Roseenblatt的主题分析非常有客观性,他甚至明确地说他并不愿判断各种作品的价值但他的说法似乎有些不对头,特别是有时赞美的尝试可能产生有趣的结果。
110、这样,对于数学家们来说是非常惊诧的,例如,薛定谔方程式并不是氢原子的准确描述,而只是某种程度上的近似值。它近似于另外一种描述磁性偶极子相对效果的方程,而这个方程本身又是一套不定量子场论方程的近似值。
