In order to avoid catastrophic accident during the limit of validity, maintenance programs should be made based on multi-site damage.In this paper, the probability of multi-site damage occurrence, propagation of multiple cracks in aircraft fuselages made in aluminum 2524-T3 and development of failure criteria are considered together.Probability of fatigue, fracture mechanics is adopted to establish the theory model of occurrence probability and growth rate of multiple cracks.A large number of tests are done to support the model.Consequently, the occurrence probability can provide a reference for establishing initial start point, the same as propagation rate to the inspection interval.

药酒的功效是不容置疑的，然而，在生活中以药酒代替食用酒饮用十分普遍，这样除了造成药品浪费以外，还易引起不良后果。 药酒和其他药物一样，是一种不同剂型的中成药，药酒是以白酒或黄酒为溶液，与不同中药混合浸制而成的。药酒主要是用于风湿疼痛，跌打损伤或体虚补养等，如风湿药酒、虎骨酒、十全大补酒等。 药酒是用来治疗疾病的，有些配方固然可以起到延缓衰老的作用，但首先必须明白，无论延年也好，益寿也好，都是以
