    • A method for accurate, on site heat flow measurement through a substrate surface using surface mounted heat flow sensors and an apparatus for on site calibration of surface mounted heat flow sensors are presented. The method comprises mounting on the substrate surface a heat flow sensor which is calibrated to establish the relationship between heat flow through the surface and the resultant induced voltage in the sensor under the convective and radiative heat transfer environmental conditions of the surface, measuring the voltage output induced in the sensor by heat flow through the surface, and converting the voltage output to a quantitative heat flow on the basis of the calibration of the sensor. The apparatus of the invention permits the calibration of the sensors under convective and radiative heat transfer environmental conditions which substantially duplicate those of the experimental substrate.
    • 提出了一种通过使用表面安装的热流传感器和用于现场校准表面安装的热流传感器的设备进行准确的现场热流测量的基板表面的方法。 该方法包括在基板表面上安装热流传感器,该热流传感器被校准以在表面的对流和辐射传热环境条件下建立传感器中的热流与传感器中的合成感应电压之间的关系,测量电压输出 通过表面的热流在传感器中感应,并且基于传感器的校准将电压输出转换成定量热流。 本发明的装置允许在对流和辐射热传递环境条件下校准传感器,这些环境条件基本上与实验基板的重复相反。
