摘　　要：本文阐述的眼震电图计算机处理系统用Apple Ⅱ plus微机对视动性眼震、前庭眼动反射、视觉——前庭眼动反射和前庭眼动反射注视抑制的眼震电图进行自动或半自动断点,计算视动性眼震最强反应期5秒内的平均增益及平均快相速度并计算前庭眼动反射、视觉——前庭眼动反射和前庭眼动反射注视抑制的最大增益及对应的快相速度。An Apple Ⅱ plus microcomputer system for quantitative analysis of nystagmus is presented, The algorithm accepts digitized data and automatically looks for the minimum and maximum (minmax)points of the nystagmus waveform. These points in turn are used to define the parameters of nystagmus, including the mean gain and the mean velocity of fast phase of optokinetic nystagmus, the maximum gain and the corresponding velocity of fast phase of vestibulo-ocular reflex, visual vestibulo-ocular reflex and vestibuio-ocular reflex fixation suppression.
