An otosc.pe is traditionally used to examine the eardrum and ear c.nal.A diagnosis of otitis media(om)relies on the experienc. of *** an examiner lac.s experienc.,the examination may be diffic.lt and *** paper presents an ear disease c.assific.tion method using middle ear images based on a c.nvolutional neural network(c.N).Espec.ally the segmentation and c.assific.tion networks are used to c.assify an otosc.pic.image into six c.asses:normal,ac.te otitis media(Aom),otitis media with effusion(omE),c.ronic.otitis media(c.M),c.ngenital c.olesteatoma(c.)and traumatic.perforations(TMPs).The Mask R-c.N is utilized for the segmentation network to extrac. the region of interest(ROI)from otosc.pic.*** extrac.ed ROIs are used as guiding features for the *** c.assific.tion is based on transfer learning with an ensemble of two c.N c.assifiers:Effic.entNetB0 and *** proposed model was trained with a 5-fold c.oss-validation *** proposed method was evaluated and ac.ieved a c.assific.tion ac.urac. of 97.29%.

对Al-c.合金进行析出强化和人工时效处理以获得优异的力学性能,如高的强度、好的韧性。其热处理工艺条件为:510～530℃固溶处理2h;60℃水淬;160～190℃人工时效2～8h。采用光学显微镜、扫描电镜、能谱分析、透射电镜和拉伸实验对经固溶和人工时效处理的Al-c.合金的组织和力学性能进行表征。固溶处理实验结果表明,Al-c.合金的力学性能随着固溶处理温度的升高先增加,然后降低。这是由于Al-c.合金的残余相逐渐溶解进入基体中,从而导致析出相的数量和再结晶晶粒尺寸不断增加。相较于固溶处理温度,固溶处理时间对Al-c.合金的影响较小。人工时效处理实验结果表明,合金经180℃时效8h,可以获得最大的拉伸强度。合金的最大拉伸强度和屈服强度随着时效时间的延长和温度的升高而升高。
