以典型海洋大气环境谱为基础,采用当量折算法,给出了各环境块参数的确定方法及加速谱与外场暴露环境的当量关系,编制了由紫外照射和周期浸润2个环境块构成的典型海洋大气环境加速试验环境谱.该谱的提出为水上飞机/水陆两栖飞机的选材和结构日历寿命评定提供了重要依据.%An accelerated corrosion environment spectrum was presented by using of equivalent conversion method based on typical marine atmospheric environment spectrum. The spectrum was composed of ultraviolet radiation and periodic soakage. The dctermination method of the parameters of every process and the equivalent relation between the accelerated spectrum and the actual use environment were presented. The purpose was to provide foundation for material selection and calendar life evaluation of floatplane and amphibian.
