温室内太阳辐射能的估算

THE ESTIMATION OF THE SOLAR RADIATION IN THE GLASSHOUSE

本文是用1984年4月—1985年3月分别在温室内外测定的太阳辐射资料,考虑了太阳高度、云量、日照时数、日照百分率等因子,采用逐步回归方法,按季节建立了三个模式,可用来估算温室内的总辐射和漫射辐射的日总量。经检验,模式误差大约在5—8％之间。

Three models based on different seasons have been established in this report, in which the datum of solar radiation was measured in the glasshouse or outside from April, 1984 to March, 1985, We considered the factors of cloud amount, insolation duration and insolation percentage, the sun-height, the radiation in the open field, etc. and used regression step by step. The three models can be used to estimate the day-total of the global radiation and diffuse radiation in the glasshouse. As a result of inspections, the average error is 5-3 percent.
