我们报告的动态校准的热电偶测量的振荡温度。在充气管中，压力周期性强迫振荡引起温度振荡，并用热电偶测量。测量的温度振荡的径向轮廓与理论的，这是从同时测量的压力确定的比较。通过改变热电偶的直径、振荡频率、管半径和工作气体，从它们之间的振幅和相位角的差获得热电偶的响应函数。利用实验中给出的响应函数，我们可以得到一个真实的温度振荡。
We report on the dynamic calibration of a thermocouple for the measurement of the oscillating temperature. Temperature oscillation is induced in a gas-filled tube by a periodically forced pressure oscillation and measured by a thermocouple. The radial profile of the measured temperature oscillations is compared with the theoretical one, which is determined from the simultaneously measured pressure. A response function of the thermocouple is obtained from the difference in amplitude and phase angle between them by varying the diameter of the thermocouple, oscillating frequency, tube radius, and working gas. We can obtain a true temperature oscillation by using the response function given in this experiment.
