校准喷嘴系统的不确定度分析方法

The Method to Determine the Uncertainty of Calibration Nozzle System

介绍了热线 /热膜流速仪的基本原理和用于热线 /热膜流速仪校准用的校准喷嘴系统的气体速度确定方法 ,分析和推导了用不确定度理论全面分析系统不确定度的方法。

This paper introduce the basic theory of the hot\|wire/film anemometer and the method to determine the flow velocity of calibration nozzle system.This calibration nozzle system is designed for the calibration of hot\|wire/film anemometer.A method to determine the uncertainty of this system is fully analyzed using uncertainty thoery in this paper.
