摘    要:针对日光温室采光面向阳倾斜而引起太阳入射光增加的事实,提出了增温系的概念和数学模型,并分析了它随时间,地点和坡度的变化规律。结果表明:纬度愈高,距冬至愈近,增温系数愈大。当采光面坡度小于当地纬度时,坡度愈大,增温系数愈大,反之亦然。

关 键 词:温室  增温系数  赤纬  纬度  坡度

Abstract:According to the fact that the sunlight absorbent-side of the sunlight greenhouse inclining to the sun caused the amount of sunlight increasing, the concept of raising-temperature coefficient and the mathematical model was raised and the rule of raising-temperature coefficient accomapanying with time, place and gradient was analysed in this study. It is concluded that the higher latitude and the nearer approaching midwinter, the bigger raising-temperature coefficient. At the condition of the gradient of the sunlight absorbent-side less than the local latitude, the raising-temperature coefficent increased with the gradient and vice versa.
Keywords:greenhouse  raising-temperature coefficient  equator-latitude  latitude  gradient
