摘要
测试了温室覆盖材料的全光辐射透过率并进行了分析比较,研究发现在太阳辐射范围,日产的明净华涂层膜表现出优异的透射性能,与温室覆盖材料理想透射曲线基本吻合。另外,新型薄膜在冬季夜间温室内热辐射集中的5～25μm波段,辐射的透过率远小于国产薄膜,为新型薄膜覆盖材料的研究提供了参考依据。热辐射透过率在一定程度上反映出材料的保温性能。
Has tested the greenhouse covering materials entire ray radiation transmissibility and carries on the analysis comparison, the research discovered that in the solar radiation scope, the new thin film displays the outstanding transmission performance, tallies basically with the greenhouse covering materials ideal transmission curve, moreover, the new thin film at night the greenhouse internal heat radiation centralized 5 -25 μm wave band radiation′s transmissibility is smaller than the domestically produced thin film far in the winter. The heat radiation transmissibility reflected to a certain extent the material the heat preservation performance.
