摘　　要：设计了多种时间装定延期体,单元延期体采用金属延期索。由4个单元延期体和1个瞬发单元构成的5瓣梅花转盘延期体可以实现瞬发、多种延期时间装定的要求,其延期时间可靠度达到0.9(置信度0.9)。Multi-time insertion delay devices were designed, and the metallic delay cord was used in the delay element. The five-petal structure, which assembled with four delay elements and one nil-delay element, can meet the demands of instantaneous and multi-delay function. The reliability of the delay time can reach up to 0.9（r=0.9）.
