“研制周期”常见的英文表达是 “development cycle” 或 “research and development (R&D) cycle”。
development cycle: 侧重于描述从概念形成到产品最终完成并推向市场的整个开发过程的时间跨度,在各类产品研发、技术项目开发等场景中适用。例如:We need to shorten the development cycle of our new products to stay competitive.(我们需要缩短新产品的研制周期以保持竞争力。 )
research and development (R&D) cycle:更明确地突出研究与开发这一特定领域的过程周期,常用于强调科研活动和技术创新项目从开始到结束的阶段时长。例如:The R&D cycle for this advanced technology took several years.(这项先进技术的研制周期长达数年。 )
