摘　　要：现阶段,有关部门对于SO_2浓度全部采用定位电解法来测试。定位电解法是通过在传感器的电解槽内使SO_2的气体发生氧化还原反应后,对产生的SO_2扩散电流进行浓度测试,虽然此方法简单应用广泛但还是会受到多方因素影响。At present,relevant departments for SO2 concentration are all made of electrolytic method to test.Positioning of electrolytic process is through the sensor makes the gas SO2 oxidation reduction reaction,to produce to test the concentration of SO2 diffusion current,and although this method is simple and universal but also are influenced by many factors.
