测量流过某一截面上的对流热流量，可以归结为测量流过该截面上各点介质的温度和速度。

The measurement of heat flux in convection through a cross section can be made by measuring the temperature and the velocity of flow of the medium at certain point of the cross section.

它简化了木质部组分传导热流和热源与环境空气的对流热流的估算(从三对热电偶减少到一对)。

This method simplified consists essentially in simplifying the valuation of the thermal conduction flux in xylem components and that of the thermal convection flux from heat source to surrounding air.

计算得出，由于热流计测头的出现，对流换热系数的变化会给热流测量带来较大误差。

Conclusions can be drawn that changes of the convective heat transfer coefficients can bring error because of the appearance of heat flux sensors.
