| 摘 要： | 本文主要介绍光纤通孔式流速旋浆传感器的结构及工作原理。把旋浆 叶轮制成中心通孔式，取代对顶式结构，从而使得起动流速低于１ｃｍ／ｓ，传感器的线性及一致性得到大大提高，在使用过程中率定系数不再变化。

| Abstract: | This paper introduces the structure and principles of the optical fiber mini-propeller probe with passing hole. A cantral passing hole type of propeller is substituted for the end-fixed structure, which makes the initial velocity to be lowered by less than 1cm/s. The calibration coefficient of the propeller has a favorable concidence and the calibrating curve has a good linearity. |
