| 摘 要： | 对4种不同品牌的日光温室EVA薄膜，在光线不同入射角及不同光照强度下的透光率进行了测定分析。结果表明，品牌间的薄膜透光率差异不显著，不同入射角下不同薄膜的透光率可拟合4次多项式，相关系数为0.9979~0.9995，极显著相关。

| Abstract: | The greenhouse EVA film of four kinds of different brands at different angles of incidence and transmittance of light under different light intensities were determined and analyzed . The results showed that the film transmittance of difference brands between was not significant,the different film incidence transmittance at different angles may be four times of different polynomial,the correlation coefficient was 0.997 9~0.999 5,it shows that correlation coefficient is significant . |
