摘　　要：阐明了飞机日历寿命的定义和组成关系式；提出了确定飞机日历寿命的原则和技术途径；指明了确定飞机日历寿命的依据、关键技术和验证方法。A review is completed on the development of calendar life in the past twenty years. The definition and composition relation of calendar life are presented. The relationship and difference between protection coating systems calendar effective time Y o  and calendar life of base corrosion propagation Y c  are presented as well as their new definitions. First D check: Y l =Y o +Y c ; Total calendar life: Y T =Y o (1+R+…+R N)+(N+1)Y c +NY s . The principle and technical way to determine calendar life are given. The key technic and foundation to determine calendar life are designated, along with its verification method.
