摘要
设计了一种适应于现场和野外工作使用、能方便地测量出热线的特征常数，以及热线的特征频率的便携式热线校准仪，具有体积小、成本低、适应性强等优点，是一种比较合理实用的热线风速仪配套产品。
A handy hotwire calibration instrument is designed, which can be used to accurately measure the character coefficient A',B' and frequency of the hotwire. This instrumentis low weight, small size, low price, easy used, and is adapted to be used outdoor and in poorcircumstance. It's a necessary accessory for hotwire anemometer.
