【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。更多还原

【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.更多还原
