摘　　要：讨论了一种类似蜂窝或V型膜的玻璃盖板与45°膜复合结构(简称45°膜结构)的光热性能。其透过率比蜂窝结构高,隔热性能与蜂窝结构和V型膜结构相当,在低纬地区应用效果甚好。The optics and performance test of the 45 degrees film structure with glass cover are described. The test results show that the transparency of this composition is higher than that of other honeycomb and V-corrugated structures, the relation of] Nu and Ra these structures are briefly introduced to verify their effect of suppressing natural convective heat loss. In a word, 45 degrees film structure has a better intergral synchronizing total effect, including transparency and suppressing natural convective heat loss, in application in low latitudes areas.
