“研制单位”常见的英文表达是 “developing organization” 或 “research and development institution/unit” 。
“developing organization” 侧重于表达正在进行研发工作的组织机构。
“research and development institution/unit” 则更明确地突出了研发（research and development）这一核心职能，institution 通常指规模较大、较为正式的科研机构，unit 可指规模相对较小或特定项目下的研发单位 。
例如：
The developing organization of this new technology is a well - known enterprise.（这项新技术的研制单位是一家知名企业。）
The research and development institution responsible for this project has made significant breakthroughs.（负责这个项目的研发单位已经取得了重大突破。 ）
