| 目的 针对我国服役飞机的腐蚀问题，实现飞机结构日历寿命的分区预测与精细化管理。方法 收集我国大气环境17个典型地区的气象环境数据，编制各地区的气候、化学环境总谱，并根据腐蚀电荷当量原理，使用铝合金、合金钢两种材料的折算系数，将各地区的大气环境向标准潮湿空气作用时间进行折算。基于系统聚类的方法，根据大气腐蚀的差异性，将17个典型地区进行分类，确定各分区的划分标准和我国大气腐蚀分区个数，并综合考虑当前文献中可查的其他地区数据资料与我国气候、降水、大气污染的分布情况，对我国大气环境进行腐蚀分区。结果 根据铝合金、合金钢的腐蚀特征量，可将我国大气环境划为5个分区。绘制了我国大气环境腐蚀分区图，给出了各分区的环境特点、地理位置分布和代表城市。结论 应用我国大气环境分区结果，可以直观掌握我国飞机不同服役环境的腐蚀严酷程度，为编制加速腐蚀环境谱、评定飞机结构日历寿命、制定针对性的维护计划和飞行计划奠定基础。 |

| Aiming at the corrosion problem of aircraft in service in China, the paper aims to release regional prediction and refined management of the aircraft structure calendar life. Meteorological environment data for 17 typical regions of China's atmospheric environment were collected. Climate and chemical environment spectra were compiled for each region. According to the principle of corrosion charge equivalence, the atmospheric environment in each region was converted to the standard humid air action time with the conversion coefficient of aluminum alloy and alloy steel. According to the differences in atmospheric corrosion, 17 typical regions were classified based on the systematic clustering method. The demarcation criteria of each subregion and then the number of atmospheric corrosion demarcations were determined. Additionally, the data of other regions available in the current literature and the distribution of climate, precipitation and air pollution in China were taken into account in the atmospheric environment corrosion demarcation of China. According to the corrosion characteristics of aluminum alloy and alloy steel, the atmospheric environment in China can be demarcated into five regions. The map of China's atmospheric environment corrosion demarcation was drawn, in which the environmental characteristics, geographical distribution and representative cities of each region were given. By applying the demarcation result of China's atmospheric environment regions, the severity of corrosion in different service environments of aircraft in China can be directly grasped, which lays a foundation for establishment of accelerated corrosion environment spectrum, assessment of aircraft structure calendar life, and formulation of targeted maintenance plan and flight plan. |
