Firstly, the paper, combining the characteristic of synchronous pulse bursts and inhibition with the modified PCNN model, presents a way of finding the foveation points in the images adaptively and effectively, and simulates the human vision system. Secondly, PCNN is extended to PCNNs, based on the properties of information couple and transmission, an algorithm that is used to fuse images of the same target got by several sensors to an image is presented to simulate the human vision system. Thirdly, combining the properties of synchronous pulse bursts, capture, and transmission and competition of waves, the paper presents two ways of classification, one is an algorithm based on the properties of neuron to capture and inhibit to classify the data taking on any complex unlinear distribution robustly, the other is based on the restricted distance and modified of the former to remove the influence of inferior samples in classification; Finally, based on the accumulative difference pictures, and the forming and transmission of PCNN wave, selecting and controlling the direction of autowave by connecting the neighbouring neurons selectively, the paper presents a way to simulate the tracks of moving object and detect the moving direction.

In brief, a concerted attempt was made to characterize this passage as a condemnation of the hubristic aspirations of movements such as National Socialism that sought a monstrous "greatness" on the basis of a total control of humanity and nature through conquest and technology; the "inner truth" of the movement could then be taken as the historical truth of a phenomenon whose profound, if unsettling, significance defines the nihilism of the times.

概言之，对这段话的解读业已取得一致——其意在谴责诸如国家社会主义之类运动的狂热性，因为此类运动谋求的是一种通过军事征服和技术征服、全面控制人类和自然的、极其恐怖的&伟大性&；此类运动的&内在真理&意指某类现象的历史性真理，其深远的、即便是令人不安的意义在于确診了这个时代的虚无主义病。

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。
