摘　　要：采用红外热成像远程动态控制系统和热电偶两种温度检测方法,对非洲菊真空预冷过程中舌状花瓣、管状花瓣和茎秆3个部位的温度进行实时检测。实验结果表明,不同部位之间降温速率存在较大差异,不同部位的温度分布也不均匀;热电偶和红外热成像检测结果相比,前者比后者平均高出4.55～10.4℃。Both thermal infrared imaging and thermocouples were applied to real time measurement of cut gerbera during vacuum cooling.Surface temperatures of the ligule-shape petal,tubular petal and stem were detected.Results show that there is a significant difference of different parts in average cooling rate,and for the petal and stem,the temperature distribution is nonuniform.The average final temperature obtained with thermal images is 4.55～10.4℃ lower than the thermocouple.
