Cummings＇ poems are popular for the whimsical form. This paper, taking his dual identity-both a poet and a painter-as a starting point, is making an analysis of his poem-picture and the relationship between his poems and the concrete poem, and illustrating the main features of the whimsical form. It is the vivid images and the mood of picture that contribute to his poems the whimsical form.展开更多
认知语言学曾提出文本分析有两个重要模型:上至下及下至上模型(Top-Down Model and Bottom-Up Model),前者从图式建构出发,后者立足于语篇结构分析。文学文本解读是两个模型共同作用的过程,是读者自身努力达到图式(schemata)与语篇特征...认知语言学曾提出文本分析有两个重要模型:上至下及下至上模型(Top-Down Model and Bottom-Up Model),前者从图式建构出发,后者立足于语篇结构分析。文学文本解读是两个模型共同作用的过程,是读者自身努力达到图式(schemata)与语篇特征平衡的能动性选择过程。文章以卡明斯诗歌为例,指出其诗难懂的重要原因之一是其独特的语篇结构缺乏激活图式所需的显性线索,进而以例析证明双向解读策略是解读卡明斯诗歌的可行方式。展开更多

The （R）-and （S）-2-n-butylbutanedioic acid 4-t-butyl esters were obtained by the resolution of the above-mentioned racemic compounds with（S）-（ - ） or（R）-（ ＋ ）-α- methylbenzylamine, respectively. The e.e. values of the two optical active products were determined to be above 99% by HPLC after the formation of two pairs of diastereoisomers with（R）-（ ＋ ）-α-methylbenzylamine and（S）- phenylalanine methyl ester.展开更多
A class of two-level high-order accuracy explicit difference scheme for solving 3-D parabolic P.D.E is constructed. Its truncation error is (Δt2+Δx4) and the stability condition is r=Δt/Δx2=Δt/Δy2=Δt/Δz2≤1/6.
