Kalium and natrium erode into brick at a high temperature in the form of simple substance and result in expansion in self-baking carbon brick, and molten alkali metal oxides adsorbed on the face of brick react with SiO2 and obtain a eutectic mixture which causes expansion at a high temperature, while carbon deposition caused by the reaction of CO and simple substance of kalium and natrium as well as the soot deposition of CO contribute to the lower temperature expansion.

结果表明：膨胀率及碱含量都随温度和时间的增加而增加，膨胀率受时间影响较大，达到8%左右，而受温度影响较小，仅为1%左右；砖内K， Na元素质量分数受时间和温度的影响均较大，分别达到4.5%，5.33%，4.28%，4.46%，且Na侵蚀较K严重；在高温下K， Na是以单质形式侵入砖体内，而熔融碱是吸附在砖体表面并与SiO2：生成低共熔化合物引起高温膨胀，在低温下砖内K，Na单质与CO发生C沉积以及CO发生烟碳沉积反应引起低温膨胀。

Third part: The relationship analysis of city expansion and the suburb farm development. First of all, city expansion has the characteristic of gradualness, regional, universality and integration. The city expansions effect is enlarging city scale, increasing the urban population and so on, Compared with other type farm, the suburb farm, lying in the city peripheral, has relatively developed economy, multipliable industrial structure, the better market growth and high the productive forces level. The city expansion changes greatly suburb farm strategic environment, urges the farm adjust its strategic development pattern.

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
