In fishing,the sliding cone blocks enter the fish cavity easily acted by a guide shoe and a guide cone,slide downward by its own weight,produce relative displacement to the guide rail slope,and the radial distance between its tooth face and the spear rod increases until it touches the inner wall of the fish cavity; while lifting the drilling string,the guide rail slope on the spear rod forces the sliding cone blocks to bite the inner wall of the tubing fished.

打捞时在引鞋和导锥的作用下滑牙块能够顺利进入鱼腔并依靠自重下滑，沿导轨外伸直至其齿面与鱼腔内壁接触；随后上提钻柱，矛杆上的导轨斜面迫使滑牙块咬紧被打捞油管内壁，当油管严重偏磨使一对滑牙块卡在磨穿位置时，另一对能有效卡在未磨损部位，同时外筒限制了油管外胀变形。

Based on a variety of books and materials, foreign or domestic, this thesis deals with the recent development and application, the past, present and future for solar energy and solar cells, analyzes the great senses of solar energy and solar cells for the development of economic, and analyzes their structure photovoltaic effect and conservation efficiency. The writer also elaborates the working principles and application characteristic of solar cell, various factors that may lead to bad conservation efficiency of solar cell. Based on the the working principles and application characteristic of solar cell, emphasizes on some ways of improving photovoltaic conservation efficiency for solar cell, for example: the appropriate thickness of solar cell, the low resistance, the phalanx of solar cell, the film of reduce the reflect of solar rays, and so on, and designs simply the feasible way, then give out the CAD frame chart .

本文是在收集了大量的国内外图书资料的基础上，对太阳能和太阳能电池的广泛应用领域、过去、现在和未来进行了探讨，分析了太阳能和太阳能电池的对我国经济发展的重大意义，阐述了太阳能电池的工作原理和应用特性，论述了影响太阳能电池光电转换效率的因素，重点介绍了几种提高太阳能电池光电转换效率的方法，例如：合适的太阳能电池厚度、降低太阳能电池的串联电阻、采用太阳能电池方阵、采用光伏发电自动跟踪系统、采用减反射膜和折面型抛物柱太阳能聚光器，并对以上可行的方法进行了简单综合设计，实现了 CAD 框图。
