In 5 healthy individuals the postrotatory, exponential constants were estimated for each of the four nystagmus qualities, viz. the velocities and durations of fast and slow components. The residual spread (Sr) of each quality in a semilogarithmic plot was also determined. The value of the constant for postrotatory decay indicated a decrease of the velocity and an increase for the duration of the slow component, both with a significant difference between individuals, while for the corresponding values of the fast components no systematic change in the postrotatory reactions was indicated, nor any difference between individuals. The constant that corresponds to the value at maximum stimulus showed differences between individuals for each of the four nystagmus qualities, while Sr presented differences between individuals only for the two slow phase qualities. This technique to describe postrotatory nystagmus reactions by the two exponential constants for each of the four nystagmus qualities together with the residual spread for each of the qualities is intended for future 'on-line' nystagmus analysis.
在5名健康个体中，针对四种眼震特征（即快相和慢相的速度及持续时间）的每一种，估算了旋转后指数常数。还确定了每种特征在半对数图中的残余离散度（Sr）。旋转后衰减常数的值表明慢相速度下降而持续时间增加，个体间均存在显著差异，而对于快相的相应值，旋转后反应未显示出系统性变化，个体间也无差异。对应最大刺激值的常数在四种眼震特征的每一种上个体间均存在差异，而Sr仅在两种慢相特征上个体间存在差异。这种通过四种眼震特征各自的两个指数常数以及每种特征的残余离散度来描述旋转后眼震反应的技术，旨在用于未来的“在线”眼震分析。
