The head is slowly turned 90° toward the side where nystagmus is induced less intensely. Then the head is rotated 180° rapidly toward the opposite side. This article reports three cases of the ageotropic form of HC-BPPV that were cured by rapid head rotation. The three cases demonstrated that rapid head rotation was an effective maneuver to treat cupulolithiasis on the utricle side. It is recommended that rapid head rotation can be used for therapeutic diagnosis: If nystagmus subsides immediately after this maneuver, the diagnosis is cupulolithias is on utricle side. If nystagmus changes into the geotropic form, the diagnosis is cupulolithiasis on canal side or canalolithiasis in the anterior arm of horizontal semicircular canal. A repositioning maneuver for geotropic form can then be applied to treat these patients.

由于神经网络技术的发展,神经网络在非线性控制方面显示出强大的优势,同时近年来出现的逆系统方法对于多变量非线性系统的控制指出了一条可算是光明的道路,鉴于以上两项技术的优越性,本文提出对BMPS进行神经网络逆系统控制的方法,首先通过机理分析的方法建立了BMPS的非线性动态数学模型,并依此模型设计了神经网络逆系统控制方案,由于此方案中需要用到球磨机磨筒内负荷的反馈,但是磨内负荷是一个不能直接测量的量,而且其测量方法是多年来人们一直在努力的方向却又一直不能较好地解决,本文提出对其进行神经网络测量的思想和方法,这一方法的仿真试验和现场实测结果均表明其研发造价低廉的优越性和测量较为准确的实用性。
