我们研究了最近提出的恒温风速测量的重新校准技术，并解决了该计划的一个基本问题。首先，考虑输出电压与线性度的偏差。然后推导并验证了预测平均偏差的方法。使用重新校准方法获得的校准曲线的梯度包括在自由落体速度下的误差，并且该误差的时间变化由二次函数近似。最后，对预测的平均误差进行了验证。
We study a recently proposed recalibration technique for constant-temperature anemometry measurements, and address a basic issue of the scheme. First, the deviation of the output voltage from linearity was considered. A method of predicting the mean deviation was then derived and validated. The gradient of the calibration curve obtained using the recalibration method includes error at the freestream velocity, and the temporal variation of this error was approximated by a quadratic function. Finally, the predicted mean error was validated.
