玻璃钢百叶箱与木制百叶箱内温湿度测量的对比分析

An Comparison of Air Temperature and Relative Humidity Measured Inside Thermometer Screen of Glass Fiber Reinforced Plastic and Timber

通过分析2005年2—7月玻璃钢百叶箱与木制百叶箱内温湿度对比试验资料,得到了两种材料百叶箱内温湿度测量的差异以及两种百叶箱间对大气温湿度变化反应速度的差异,并分别讨论了不同云量、不同风速条件下,两种材料百叶箱气温测量差值的变化。结果表明:两种材料百叶箱内测量的气温平均差值在0.1℃以内,差值标准差在0.2℃以内,相对湿度平均差值在0.4%以内,差值标准差在2.1%以内;玻璃钢百叶箱对大气温湿度的反应比木制百叶箱快或相当;无论在多云和少云条件下,还是高风速和低风速条件下,两种百叶箱内测量的气温差值普遍在0.1℃以内。

Based on the comparative test data from February to July in 2005, the difference of air temperature / relative humidity measured inside the thermometer screen of glass fiber reinforced plastic and that of timber are analyzed. In the meantime, the difference of response speed to air temperature as well as relative humidity changes in the two kinds of screens is analyzed. The impact of various cloud cover and various wind velocity on the difference of air temperature measured inside the two screens is discussed. The result indicates that the mean difference of air temperature inside the two kinds of screens is within 0. 1℃, the standard deviation of the difference is within 0.2℃. The mean difference of relative humidity inside the two kinds of screens is within 0.4%, the standard deviation of the difference is within 2.1%. The response to air temperature / relative humidity inside the thermometer screen of glass fiber reinforced plastic is almost faster than that in the screen of timber. No matter under what cloud cover or what wind velocity, kinds of screens is almost within 0.1℃. the mean difference of air temperature in the two
