热流计的标定通常是在参比条件下进行的,如果实际使用条件同标定条件不同,将会造成热流计的示值在不同程度上偏离于实际值。本文就不同的对流换热系数和不同被测物体的导热系数对热流计示值的影响作了定量分析,并借用电子计算机得出了修正值,这对提高热流计的精确度有很大的意义。 The calibration of the heat flow meter is usually performed under the reference conditions. If the actual usage conditions are different from the calibration conditions, the indication of the heat flow meter will deviate to some extent from the actual value. In this paper, different convective heat transfer coefficient and the thermal conductivity of different objects on the measured value of the heat flow meter made a quantitative analysis, and borrowed the computer to obtain the revised value, which is to improve the accuracy of the heat flow meter has a great significance.
