| 中文摘要: |
| 根据天水温室生产季节太阳活动特征,建立了温室主要建棚指标数学模型。通过各指标量化计算,并结合天水市地理地形特征和近3年温室气象条件观测,得出天水温室相同高度、跨度下,圆—抛物曲面组合型"二代"节能日光温室采光、保温性能最优。其适宜的建造指标为:温室方位角(偏西)7°～9°,采光屋面坡度29°～32°,后屋面仰角42°～45°,中脊高3.0～3.5m,跨度7～8m,墙体厚度0.8m(顶墙厚)～1.0m(底墙厚)。 |
| 英文摘要: |
| On basis of the seasonal movement of the sun during the operation period of the greenhouses in Tianshui city, a mathematical model for building a greenhouse was set up. The geographic in characteristics of Tianshui and the datas of the main structure of the greenhouse, in recent years were analysed. Under the same height and span, the type of dome-arch structure is the best one to collect sunlight and hold heat. The indexes for building a greenhouse were: greenhouse azimuth at 7°～9°, the gradient of sunlight-intecepting roof at 29 ° ～ 32 °, the elevation of the back roof at 42 ° ～ 45 °, the fastigium height at 3.0 ～ 3.5 m, the span at 7 ～ 8 m, the wall thickness at 0.8 m(top ) ～ 1.0 m(base). A scientific theory basis also had been provided. |
