Scientific and technical translation (sci‑tech translation) refers to the translation of texts concerning science and technology. It is a branch of applied translation, focusing on conveying scientific and technical information accurately between different languages.
科技翻译，指对科学技术类文本进行的翻译，属于应用翻译的分支，重在不同语言之间准确传递科技信息。
In a broad sense, the scope of sci‑tech translation covers all texts related to scientific research and technological activities. It includes scientific papers, research reports, patents, technical specifications, product manuals, standards, engineering documents, popular science articles and academic monographs.
广义上讲，科技翻译范畴涵盖一切与科研、技术活动相关的文本：科研论文、研究报告、专利、技术说明书、产品手册、技术标准、工程文件、科普文章、学术专著。
In a narrow sense, sci‑tech translation mainly focuses on specialized professional documents in natural sciences and engineering technology, such as technical manuals, patent documents and engineering contracts. Popular science writings, though related to science, are sometimes treated as a separate sub‑category because they aim to spread knowledge to ordinary public readers.
狭义上，科技翻译主要指自然科学、工程技术领域的专业文献，如技术手册、专利文件、工程合同。科普读物虽和科学相关，面向普通大众普及知识，有时被划为独立子类。
Sci‑tech translation deals with objective, factual information. Its core task is to transfer technical meaning faithfully. Compared with literary translation which emphasizes artistic appeal and aesthetic value, sci‑tech translation puts accuracy in the first place. Objectivity, accuracy and strict logic are its prominent features.
科技翻译处理客观事实信息，核心任务是忠实传递技术含义。和侧重艺术感染力、审美价值的文学翻译不同，科技翻译把准确性放在首位；客观性、准确性、严密逻辑性是其突出特征。
Sci‑tech translation involves many subject fields: physics, chemistry, biology, medicine, computer science, machinery, civil engineering, environmental science and so on. Translators are required to master not only bilingual competence, but also relevant professional background knowledge. Misunderstanding of technical concepts will directly lead to translation errors.
科技翻译涉及众多学科领域：物理、化学、生物、医学、计算机、机械、土木工程、环境科学等。译者不仅要具备双语能力，还需要相关专业背景知识；对技术概念的误解会直接造成翻译错误。
With the development of global scientific and technological cooperation, sci‑tech translation plays an increasingly important role. It promotes international academic exchange, technology import‑export and technical popularization.
随着全球科技合作发展，科技翻译作用愈发重要，推动国际学术交流、技术引进输出与科技知识普及。
