Abstract: | By using the ways of factor analysis,the information from temperature parameter series and radiation parameter series was extracted.Excluding the time factor and using data analysis software,the states of greenhouse were classified based on the value of greenhouse factor.Then the discriminant function of each type was calculated.The change rate interaction of temperature and humidity in the greenhouse in distinct category was analyzed.The interaction function was obtained. |
