摘　　要：污染源排放废气流速通常在7～15m/s之间。通过S型皮托管在低速风洞中与标准皮托管的对比实验说明,在10m/s,15m/s两种情况下,皮托管迎风面截面变化对皮托管系数Kp的影响很大,实验结果可供污染源废气监测和皮托管定期检定进行参考。The velocity of waste gas of pollution sources is usually within the range between 7-15 m/s. The effects of the alternation of cross-section of S-type pitot tube windward side on the pitots tube coefficient （Kp） in two conditions, 10 m/s and 15 m/s, were illustrated through the comparative experiments of placing the S-Type pitot tubes and standard pitot tubes in the low speed wind tunnel respectively. This will provide references for the monitoring of pollution sources waste gas and the periodic verification of the pitot tubes.
