摘要

Abstract

The Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction (the BBNJ Agreement) entered into force in January 2026. While large language models have improved the translation efficiency of the agreement

they suffer from a notable lack of legal commensurability in translation outputs. Grounded in the theory of legal commensurability in legal translation

this study systematically sorts out the legal connotations of core terms in the BBNJ Agreement

and clarifies the legal standards

technical requirements and evaluation dimensions of commensurability. It focuses on analyzing how to strike a balance among semantic consistency

legal applicability and cultural adaptability in legal terminology translation. Meanwhile

this study explores how to transform commensurability requirements into enforceable prompt constraint rules

and designs prompt templates applicable to large language models. Through comparative tests

it verifies the effect of prompts on improving translation commensurability

and finally constructs a legal compliance evaluation system for BBNJ terminology translation prompts

so as to provide normative guidance for AI translation of international law of the sea treaties.
