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。

Based on in-depth research on solar and electricity energy control technology,this paper designs a new controller for solar heater system with the core of PIC16F877 microcontroller using modern fuzzy control technology. Accordingly, a series of hardware electro circuit is also established in this paper, which can be used to measure and display and control and dialogize between customers and the controller. Furthermore, system reliability is well guaranteed by means of some hardware anti-jamming measures.

Looks by far, sees only these grotesque planetoids, some elephant potato, some elephant duck egg, but also some simply indescribable, in which biggest diameter almost has 890 kilometers, but the smallest diameter on several centimeters sizes, is also similar with the small bird's egg, in vast outer space naked eye nearly blind, obviously between these planetoids has the huge difference; Luckily this circles the planetoid which the sun moves, besides appearance irregular, knows one's place extremely, moreover the ingredient quite is unitary, majority all is the lithical meteor, they then receive the outside space powerful disturbance, or suffers other photostar hit in the situation, only then has the possibility the star to cause the damage to peripheral other solar system in.

远远望去，只见这些奇形怪状的小行星，有的像土豆，有的像鸭蛋，还有的简直无法形容，其中最大的直径差不多有八九十千米，而最小的直径也就几厘米大小，跟小鸟蛋差不多，在浩瀚的太空中肉眼几乎看不到，可见这些小行星之间存在着巨大的差异；幸好这一圈绕太阳运行的小行星，除了模样参差不齐之外，还是非常安分守己的，而且成分比较单一，大多数都是石质陨星，它们只有受到外界空间强有力的干扰，或遭受其他星体撞击的情况下，才有可能对周边的其它太阳系内星球造成伤害。

A planet on the other hand is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.

行星演化与恒星不同：恒星形成之后，周边的气体尘埃云冷却之后凝结形成，成为行星雏形，众多小行星雏形聚合碰撞，演化成成熟的行星；没有内部的核聚变；质量超过木星13.6倍，就会产生核聚变，如果还未至木星86倍，尚处于棕矮星的阶段，将会向恒星演化；持久的核聚变需要足够大的质量来支撑，温度也不足支撑氢向氦的转变。
