| 摘 要： | 空中环境谱是飞机使用环境谱的重要组成部分。首先对影响飞机结构完整性的污染物元素浓度进行了空测，其次应用模糊聚类理论确定了空中环境谱的水平区域尺度大约为200 km，高度区域尺度大约为2 km，最后应用SPSS统计软件研究了污染物元素浓度随高度的分布规律，得到了统计意义上的预测模型，预测结果与实测结果有“较好”的一致性。

| Abstract: | Aerial environment spectrum of aircraft structure is the important part of the service environment spectrum of airplane. In this paper, above all,the air polluter density are measured by air. Then, the horizontal area scale is approximately 200 km by the application of fuzzy set theory and the high extent is approximately 2 km. At last, the distributing law of polluter density with the height is studied by SPSS and the forecast model is gained. The forecast results are in better agreement with the measured results. |
