Research on Chinese Translation of Mechanical Engineering English Lexis and Syntax in MTPE Mode—A Case Study of DeepSeek

As globalization accelerates, international exchanges and cooperation in mechanical engineering have grown increasingly frequent, driving a steady rise in demand for translation. As traditional human translation tends to be relatively inefficient, and pure machine translation struggles to meet industry quality standards, the MTPE (Machine Translation Post-Editing) model has come into being. This study uses DeepSeek as a case study to explore post-editing strategies for mechanical engineering English under this model. As a key branch of scientific and technological English, mechanical engineering English plays a vital role in disseminating mechanical engineering expertise and facilitating international exchanges and cooperation. Such texts are marked by distinct features, strong professionalism, and considerable difficulty. At the lexical level, they employ a wealth of technical terms, nominalized structures, and abbreviations. At the syntactic level, passive voice and long, complex sentences are frequently used. Under the MTPE framework, this paper first outlines the research background, then analyzes domestic and international research on post-editing strategies for mechanical engineering English, identifies existing gaps and shortcomings, and highlights the innovations of this study. Next, it examines the strengths and limitations of DeepSeek in translating mechanical engineering English. It then offers a detailed overview of this mode, covering its core concepts, functional scope, and the specific advantages it brings to mechanical engineering English translation. By analyzing the linguistic features of mechanical engineering English at both lexical and syntactic levels, this paper selects several translation samples to explore post-editing strategies for words and sentences in this domain, aiming to provide practical insights that can enhance the quality and efficiency of mechanical engineering English translation.
