| 摘 要： | 烟道气中的二氧化硫干扰因素多，不容易测准．本文通过对比实验认为．影响采样精度和分析准确度的干扰因素有：（１）转子流量计的影响；（２）冷凝水对二氧化硫的吸附；（３）氮氧化物对测定的干扰。严格控制上述实验条件，即可得到准确的二氧化硫浓度值。

| Abstract: | The interference factors on determination or SO2 in fluepo is complex,and no easy to determine exactly. In this Paper. by theCorrelation experiments, we think the interference factors of determination are: (1 )the correction of rotameter now meter ; (2 )the absorption of SO2 by condensing water ; (3)the interference of NOx. If controlled strictly such experimental condiations, the exact concentrationvalue will be obtained. |
