最后，文章以"情感与想象"、"象征与表现"为中心，通过思想观念、价值取向、表现技法等方面的分析，探讨了屈骚诗学对中国现代浪漫主义、现代主义的建构性作用，从中显现出现代文学根据西方改造传统、根据传统会解西方的"异化"与"归化"的双重特征。

Based on these results and other data, we try to interpret the geodynamical features of the Tianshan orogen.

根据计算结果，对新疆天山地区的构造动力学特征进行了分析和推断，认为天山处于地幔对流形成的挤压沉降环境中，在南北不对称的挤压应力作用下快速隆升，挤压应力场中心在天山以南。

Hand in hand with that, we must frankly recognize the overbalance of population in our industrial centers and by engaging on a national scale in a redistribution in an effort to provide better use of the land for those best fitted for the land.
