Background Otitis media with effusion is a highly concurrent disease in young children with adenoid hypertrophy.The aim of this study was to assess the middle ear effusion and audiological characteristics in children with adenoid hypertrophy and compare the various assessment methods.@@Methods Two hundred and seven candidates who were to undergo adenoidectomy were analyzed using otoscopy,tympanometry,air-conduction auditory steady-state responses (AC-ASSR),and computerized tomography (CT) before adenoidectomy.@@Results About 73.4％ (304/414) of ears were confirmed to have middle ear effusion (MEE) by otoscopy; 75.4％ (312/414) of ears revealed MEE by CT.CT scan correctly predicted all the myringotomy results,giving 100％ accuracy on the diagnosis of MEE.Additionally,CT revealed two children with inner ear malformations.Type B tracing tympanogram provided a sensitivity of 91.7％ and a specificity of 92.2％.Type C tympanogram with peak pressure

针对单目运动像机无法确定点状运动物体三维位置的难题,提出了一种求解点状运动物体三维位置的方法,利用直线在其法平面上的投影为点这个特性,将各时刻像机光心与物体位置的连线(以下称观察视线)投影到以运动物体轨迹为法线的平面上,通过迭代使其投影线交于一点,交点对应的直线就是物体的运动轨迹,仅需要取大于等于5个时刻的数据就可以确定物体的运动轨迹。假设物体作匀速直线运动,根据各时刻像机内外参数以及运动物体的成
