According to heat balance theory, we calculate three kinds of average temperature of solar energy preservation pigpen in the coldest month. we analyze economic, social and zoology benefit of pigpen by dynamic cash analytic method and draw conclusion that we can increase pig ' s growth, diminish consuming of feedstuff, decrease raising cost, increase farmers " income. improve agricultural zoology environment by adopting solar energy preservation pigpen which is an item with economic, social and zoology benefit
對太陽能保溫豬舍的保溫性能、吸收太陽能的能力進行了定量計算和分析;根據

The temperature distribution on the high temperature side of an electric tunnel furnace is analysed and simulated on the basis of the principle of thermal radiation by the way of thb ( thermal heat balance ). the heated silicon carbon sticks are decomposed into innumerable tiny heating faces, which exchange the heat with the heated materials. a numerical model based on the radiation intensity law is constructed to calculate the energy absorbed by the heated materials and simulated by a computer. the results showed that the even distribution of temperature can be obtained by optimizing the arrangement of the silicon carbon sticks according to the calculation results to make the structure design more reasonable. these calculation results have been used in the practical designs and the expected objectives achieved

The first geologic reason for degeneration of the eco - environment in the headwater area of the yellow river is that the increase of the recent geologic function caused desertification and grasslands resource decreased and underside changed, destroied the balance of water - air - heat in the area ; the second is that the water environment changes by the degradation and atrophy of frozen earth cause multilayer and synthesis cause of formation degeneration of the eco - environment ; the third is that the man and rats function accelerated degeneration of the eco - environment in the headwater area of the yellow river
