Contraposing the measurement principle of the traditional hotwire air mass flowmeter , the reason of the excursion of the result for flow measurement was analyzed and inferred when environment temperature changed ; the method for temperature compensation and the realization circuit was given ; and compared the theory output of the new type hotwire air mass flowmeter with its real output after temperature compensation 摘要針對傳統型熱線式空氣質量流量計的測量原理,分析和推導出當環境溫度變化時對流量測量結果產生偏移的原因;提出了一種環境溫度的補償方法和具體的實現電路;并對經環境溫度補償后的一種新型熱線式空氣質量流量計的理論輸出和實際輸出進行了計算與比較。

The theoretical calculation and the experimental result indicated that , after temperature compensation , this kind of new hotwire air mass flowmeter still had high measuring accuracy when the environment temperature had wide range change 理論計算和試驗的結果表明,經環境溫度補償后,這種新型熱線式空氣質量流量計在大范圍環境溫度變化下仍具有較高的測量精度。

I hotwire a parked cab and stay under the speed limit so as not to get any attention 我弄了輛停在路邊的出租車盡量不超速,以免引人注目
