The complex fault depression is a combination of two or more half grabens, with each of these grabens having its own independent sediment-supplying systems. Once these half-grabens were filled, they would have an uniform sediment-supplying system and drainage system and would continue to develop as a larger entity of the faulting depression.

Chapter 3 proceeds with thecomparative analysis of both the Source Text and different TTs within theframework of text linguistics. The core analysis concerns cohesion feature of the textbased on the theory proposed by Halliday and Hasan, and the coherence featureapplying Paul Grices Cooperative Principle. Therefore, the evaluation of the threeversions is achieved.

在第三章中，本文着手在文本语言学的框架内进行《洛丽塔》源语文本与不同的目的语文本的比较分析，核心运用韩礼德和哈桑提出的衔接理论来研究文本中的衔接，运用保罗·格赖斯提出的合作原则来研究文本中的连贯，从而对三个译本质量进行评估。
