1·The spatial distribution of the flux density is investigated by the CCD method and calibrated by heat flow meter.

采用CCD法得到了能流密度的相对分布并用热流计标定出能流密度分布。

2·The flux and the temperature difference between inlet and outlet of the heat-supply system must be measured when measuring heat flux by heat meter, and then the result can be calculated.

目前的热流计在测量热量时需要测量供热管道的流量以及进出口温度，然后再对其进行积分计算。
