Based on the traditional geometric optics principles and the method of ray tracking, this paper reports the calculation of the aberration of the mode index lens when the collimated beam incidents upon it inclinely with an angle, and the divergency of the output beam from the MIL when it works as a collimator for the end-butt coupling between the semiconductor laser and the waveguide.

This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving

本文分析研究了太阳能热泵热水系统的分类及技术特点，直膨式太阳能热泵技术国内外发展趋势，从六个方面对直膨式太阳能热泵热水系统的研究进行了归纳总结；在此基础之上，从太阳辐射的最佳接收考虑，提出了集热器／蒸发器为圆台侧面的圆台型直膨式太阳能热泵热水器的设计模型，理论上分析了这种热水系统所接收的太阳辐射和得热量，并与圆柱型、平板型的直膨式太阳能热泵热水系统进行对比分析，通过计算机辅助模拟计算出：系统不但可以有效地吸收太阳能，还能有效地吸收空气中的热量，具有良好的热性能；在昆明，以2月为代表的冬季，其太阳辐照较低，系统的制热系数COP值也能达到4.2，效能比EER值为2.9；系统的得热量高出圆柱型、平板型的直膨式太阳能热泵热水系统，节能效果明显。

On the other hand, the influence of Absurd drama manifested mainly in the perspective of observing the world in later plays. Absurd drama reveals the uncertainty of the world by the skill of"simile way". Contemporary playwrights draw extensively and broadened the use of"simile way", and create the new simile symbols: anti-classic simile, anti-system simile and anti-meaning simile. At the same time they use a comprehensive simile to create a kind of sensual drama.Absurd drama also destroys the language function of traditional drama by rupture and desegregation, also tends to use "the language of no meaning," to reflect the world's essence. The contemporary generation create a physical theatre to expulse of the role of language. Another extreme is to strengthen language function thus creating a language game.

另一方面，荒诞派戏剧的影响力主要体现在后世剧作对客观世界的认知上：荒诞派通过&直喻&的手法来表现世界不确定性的本质，被后世剧作家广泛借鉴并且拓宽了直喻手法的使用，出现了反经典、反系统和反深度的直喻符号，同时另一个极端则是用剧场性的全面直喻创造了具有震撼力的感官戏剧；荒诞派通过破裂与解体的方法化解了传统戏剧的语言功能，更倾向于用&无义的语言&表达来体现世界的无义，后世剧作家在此基础上索性彻底驱逐了语言的作用从而创造了肢体戏剧，另一个极端则是强化语言功能创造了&语言游戏&。

From the bottom up, the strata are the Fuxian, the Yan'an, the Zhiluo and the Anding Formations. In the past, it was thought that only the Yan'an Formation contains coal in the Jurassic systerm of the basin. However, recent explorations have shown that the Zhiluo Formation also has some minable coal seams in a certain area.
