The results show that wet air reduces both fatigue life and strength with the influence-factor of 0.6059 and 0.8722, respectively. Wet air environment enlarges the dispersivity of fatigue life, therefore using the corrosion-influence-factor obtained by eigenvalue or mean value to predict the fatigue life with high reliability will cause an unconservative conclusion.

成像雷达由于成像机理的原因不可避免地会引入相干斑噪声，因此直接利用SAR图像进行处理会导致过多的虚警发生，为了减少相干斑的影响在对SAR图像处理的同时引入了中值滤波，因此在很大程度上消除了SAR图像中的噪声干扰。

Aiming at the attributes of the high speed of cigarette package moving and strong noise in the field environment, the thesis carries out a dynamic imaging mode of random outer trigger and obtains the cigarette package images with high quality and high precision. The median filtering, image segmentation and other techniques of image pre-processing are applied to the character images, and the techniques of pattern recognition are employed to recognize the characters. The thesis optimizes and improves the recognition algorithm to satisfy the requirements of high speed real-time processing system. The whole system can online inspect and take statistics the print quality of the forgery-proof symbols on the outer packing of cigarette, achieving good results.
