Facility status monitors a system to accumulate and assist diagnostic tool as a data is the inevitable result of the development climate that equipment maintains. 20 centuries since 60 time, as the rapid development of electronic technology and computer technology, industrial production is moderner and moderner, the facility status technology that monitor also develops subsequently with diagnostic technology rise.

The experimental data demonstrated that there was a nasalward directional preference in oath OKN system under both close loop and open loop conditions, and the nasalward OKN gain evoked by stimulation of nasal retina was much higher than that at temporal retina. ms indicates that OKN nasalward preference is mairily derived from the nasal retina, i. e. the direct path1Vay of OKN dominates the indirect pathway in cat's OKN system. The gains of temporalward and nasalward OKN from temporal retina are much less than those of nasalward OKN from nasal retina. It is suggested that the indirect pathway of OKN in the cat only possesses a supplementary function, Which probably plays an important role in temporalward OKN eye-movments in relation to binocular vision.

实验结果显示：高速度刺激的闭环OKN反应及开环OKN反应均对鼻向运动刺激有明显的方向选择性；半侧视网膜刺激时，鼻侧半视网膜的鼻向OKN增益明显高于颞侧半视网膜的鼻向增益，说明猫的OKN眼动反应以跟踪鼻向运动为主，并且这种对鼻向运动刺激的选择性主要来源于鼻侧半视网膜，亦即来源于OKN直接通路；颞侧半视网膜的鼻、颞向眼动增益均明显低于鼻侧半视网膜的鼻向眼动增益，说明猫的OKN系统的间接通路在OKN眼动控制中起辅助作用，并可能主要对颞向OKN眼动起作用从而与双眼视觉功能相关。
