摘要
为了适应检测大气中低浓度二氧化硫的需要,提出两个物理模型来定量分析反应室的横截面半径和内壁吸光率对反应室信噪特征的影响,计算结果表明存在一个最佳的半径,为反应室的优化设计提供理论依据。
In the need of the determination of low concentration of sulfur dioxide in air, two physical models are presented for studying the effect of both the radius and the absorption coefficient on the performance of cell. The numerical results indicate that there is the most reasonable value for radius, which become theoretical base for the optimization of cell.
