摘　　要：研究了有氧情况下同时分析气相中SO2和NO含量的容量分析法。研究和设计了该方法的吸收采样流程,探讨了该方法的操作条件和干扰因素等。结果表明,该方法具有较高的精确度和准确度,操作简单,费用低,不需标准物。若在吸收采样流程前增设除尘装置,该方法可同时分析大气和燃煤烟气中的SO2和NO含量。The volumetric analysis method for simultaneously determining SO_2 and NO in gas at presence of O_2 was studied.The absorbing process and unit was studied and designed.The operating conditions and affecting factors were explored.The results show that it is characterized by good precision and accuracy,simple operation,lower cost,no standard substance,etc.If an upflow dust collector is installed,the contents of SO_2 and NO in the air and flue gas can be determined simultaneously by the method.
