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。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
