"技术名词命名法" can be translated into English as "nomenclature for technical terms" or "naming convention for technical terminology".
"Nomenclature" refers to a system or set of rules for naming things, especially in a scientific or technical context.
"Naming convention" is a more general term that describes the rules or guidelines used for naming items, including technical terms.
Both expressions are appropriate, but "nomenclature for technical terms" might be slightly more formal and specific to the field of naming technical terminology. "Naming convention for technical terminology" is more straightforward and widely understandable.
