Abstract: Technical terms are closely related to the development of a discipline while the translation of foreign terms can likewise promote the flourishing of the industry from the inter-lingual and across-cultural perspective. The article analyzes the relevance of term translation to the development of civil aviation and opts for some typical examples to expound dialectical unities between synchronic and diachronic relationship. Terms, which are subject to dynamic changes, require progressive normalization to keep pace with scientific development.

Key words: term translation, dynamic change, normalization, development of civil aviation
