The present invention provides a reinforced tape including a visually transparent backing layer, a reinforcing scrim preferably of fibers made of visually transparent material along one surface of the backing, and a layer of transparent adhesive covering but not totally wetting the reinforcing scrim so that the scrim is visible along the backing layer before the tape is applied to give a user a visual indication of the strength of the tape.

本发明提供了一种增强胶带，包括一个视觉透明背衬层，位于该背衬一个表面上的一种优选由视觉透明材料制成的增强稀松无纺织物，和一个视觉透明粘合剂层，覆盖但不完全润湿该增强的稀松无纺织物，因此在应用该胶带之前，该稀松无纺织物在背衬层上是可见的，给使用者提供了胶带长度的可视指示。

3D control of micropositioning, the environment for human-computer interaction based on the micro stereo image displaying, and microinjection are three focuses of this dissertation.The imaging models of CMO micro stereoscope and G micro stereoscope used in microvision subsystem are deduced. According to the imaging models, 3D visual servoing model based on image for micropositioning is set up. The technology of tracking and matching on the feature of image, which are relevant in visual servoing, is studied. Two arithmetic for avoiding obstacles, rolling/surrounding and curved tracking based on the depth first search, are further discussed.

The Conclusion offers a future outlook on the theory of simulacra from two perspectives. One locates simulacra in the context of visual cultural and explores viable expansions of the theory in terms of visuality, cross-disciplinarity and visual literacy. The other offers a "theoretical imagination" on the reconstruction of the logic of simulacra and its research future from the angels of the disenchantment of technology, the alternative logic of simulacra and the simulacra of humans.

余论部分从两方面做了展望，一方面将仿像置于视觉文化的语境，从视觉性、跨学科和视觉教养三个角度寻求拓展仿像理论的可行方法；另一方面在技术的祛魅、仿像的另一种逻辑和人的仿像三个角度对仿像逻辑的重建和仿像研究的未来可能性上进行了"理论想象"。

Heritage of symbol system is contributable to art education. The criterions of visual art creativity deserve thinking seriously; might problems are the turing points of visual art creativity.

On one hand, he depicts the real urban life in great detail, say, the migrant works busy dismantling and constructing, and view of the streets; on the other hand, the presentation of images are not real, for example, the exhaust pipe does not accord with its real proportion, but forcibly and excludingly occupies the picture.

正基于此，一方面，艺术家对真实的都市场景进行了细致的描绘，注重局部情节的叙事特征，比如，那些工地上忙碌拆与建的民工，道路两旁的街景等等，都是来源于现实生活的视觉经验；但另一方面，艺术家又强化了图像在视觉表达上的不真实感，例如，画面中那些排气管就是经过主观处理了的，它们完全不符合视觉再现的比例，它们的出现无疑也是对画面空间的侵占，它们既是强势的，也是&排它&的。

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.
