关于代数L-domain的一个刻画定理

引入了强core紧拓扑空间的概念,给出了代数L-domain的刻画定理,其主要结果是:偏序集D是代数L-domain当且仅当对每个强core紧拓扑空间X,函数空间[X→D]是代数L-domain.

On the empirical equivalence between special relativity and Lorentz׳s ether theory

In this paper I argue that the case of Einstein׳s special relativity vs. Hendrik Lorentz׳s ether theory can be decided in terms of empirical evidence, in spite of the predictive equivalence between the theories. In the historical and philosophical literature this case has been typically addressed focusing on non-empirical features (non-empirical virtues in special relativity and/or non-empirical flaws in the ether theory). I claim that non-empirical features are not enough to provide a fully objective and uniquely determined choice in instances of empirical equivalence. However, I argue that if we consider arguments proposed by Richard Boyd, and by Larry Laudan and Jarret Leplin, a choice based on non-entailed empirical evidence favoring Einstein׳s theory can be made.

从语用学的角度浅谈实用文体的翻译

本文从语用等效理论角度探究实用文体翻译。语用等效翻译即译者力求译文接近或等于原文的效果，既要注意具有明显民族文化特征词语的翻译，也要注重对“言外之义”的理解与传达。

On Translation of Long Sentences Based on the Novel-Of Time and the River

Of Time and the River is a famous novel written by American novelist–Thomas Wolfe who was a major American novelist of the early 20th century.His books are well received among Chinese readers.In the novel—Of Time and the River,we can find Wolfe’s frequent use of long sentences.In this paper,the skills of translating long sentences and the ways of analyzing sentence structures are discussed by several examples selected from the novel.Based on my own translation,we can find the importance of sentence structure analysis in translating long sentences.
