摘　　要：通过阐述夏季玻璃温室内四种主要降温系统,即自然通风系统、机械通风系统、湿帘-风机系统和湿帘-风机+外遮阳系统工作时室内温湿度变化趋势,并采用回归分析的方法建立温室内温度和湿度的定量关系,同时,运用线性函数、对数函数、二项式函数、乘幂函数和指数函数对温湿度变化关系进行拟合.结果显示,四种降温方式都是二项式函数的拟合程度最好,其相关系数最高,分别达到0.984 7,0.972 5,0.981 3和0.980 6.This paper is devoted to describing the change trend of temperature and humidity in summer inside glass greenhouses equipped with the natural ventilation system,the mechanical ventilation system,the wet pad and fan system or the wet pad and fan ＋ outside sun-shading system.Regression analysis is employed to investigate the quantitative relationship between the indoor temperature and humidity,and linear function,logarithmic function,binomial distribution function,power function and exponential function are used to carry out the fitting between the change in temperature and humidity.The binomial function gives the best fitting for all the four cooling systems,the correlation coefficient being 0.984 7,0.972 5,0.981 3 and 0.980 6,respectively.
