本文给出了用小型零点传感器和加压探头载体相结合测量高焓空气等离子体中径向热U_X的一些初步结果。热UX量规是一个非常简单的小铜柱，直径5 mm，球头。采用深度安装的热电偶，采用非整数系辨识方法，解决了热传导反问题。该装置的校准是使用提供已知可靠辐射热UX的高功率半导体激光系统进行的。对于一个具有代表性的等离子体，确定了热UX，并得出了第一个结论。
The paper presents some rst results of radial heat ux pro le measurements in a high enthalpy air plasma ow using a miniaturized nullpoint sensor in combination with an airpressurized probe carrier. The heat ux gage is a very simple small copper cylinder with a diameter of 5mm and spherical head. An in-depth mounted thermocouple is used to apply the non-integer system identi cation method allowing for solving the inverse heat conduction problem. The calibration of the setup is conducted using a high power diode laser system providing a known reliable radiation heat ux. For a representative plasma ow, the heat ux has been determined and rst conclusions are drawn.
