目的 利用费效分析对不同类型航材的封存包装方式进行评估。方法 针对不同类型的航材，利用灰色层次分析法计算不同封存方法的效能指标，将封存包装费用分解，利用数据拟合方式分别得到不同类型费用的曲线，通过效能-费用比确定不同类型航材的最佳封存方式。结果 封存的效能-费用比与航材体积相关性较强。对体积较小的金属类航材，气相封存的效能-费用比最高，特别是航材的价值也较小时，气相封存的优势明显；体积大于1500 cm3的金属类航材，综合封存方式效能-费用比最高；对于机载设备类的航材，综合封存的效能-费用比始终高于干燥空气封存。结论 价值和体积都较小的金属类航材应选择气相封存，其余金属类航材和全部机载设备应当选择综合封存方式。

The work aims to evaluate the preservation methods for different types of aviation materials based on cost-effectiveness analysis. With respect to different types of aviation materials, the grey AHP was used to calculate the efficiency indexes of preservation methods. The preservation cost was decomposed and the curves of different types of costs by the data fitting method were obtained. By means of effectiveness-cost ratio, the best preservation methods for different types of aviation materials were determined. There was a strong correlation between effectiveness-cost ratio and volume of aviation materials. For the smaller metal aviation materials, the effectiveness-cost ratio of vapor phase preservation was the highest. Especially, when the value of the aviation materials was also small, the advantages of vapor phase preservation were obvious. When the volume of metal aviation materials was larger than 1500 cm3, the effectiveness-cost ratio of comprehensive preservation method was the highest. For the aviation materials of airborne equipment, the effectiveness-cost ratio of comprehensive preservation was always higher than dry air preservation. Metal aviation materials with small value and size should choose vapor phase preservation. Other metal aviation materials and all airborne equipment should choose comprehensive preservation.
