heat-flow meter造句

• In this paper , a image processing method has been presented , with this method mean temperature of testing object can be arrived at from infrared picture and the interior temperature gradient of the test pieces in the situation of transient heat transfer can be got . unsteady - state heat transfer mechanism of wall has also been studied in this paper . on the basis of theoretical analysis and experimental study we can get such conclusions : infrared testing of energy conservation of buildings is rapider and more accurate than heat - flow meter method which is popular at present ; heat transfer mechanism in the situation of unsteady - state heat transfer has been analyzed through experiment ; the interior layers ’ temperature of the test pieces ascent in company with
  本文在理论分析和试验研究的基础上得出以下结论:本文研究的红外检测建筑节能的方法比目前存在的热流计法更快速、更准确;用试验分析了墙体在非稳态传热情况下的传热机理;试件各层温度随着受热面环境温度的上升而上升,只是上升的程度不同,响应时间不同,这是由于试件内部有一个蓄热过程;通过传热理论和建筑热工计算推导出了非稳态传热情况下的传热系数的计算公式;本文用matlab进行红外图片的处理,进而得到被测物的平均温度;用数据处理软件拟合温度热流。
