【Abstract】 Sampling capabilities of Andersen acid rain sampler and guotai acid rain sampler were compared. Monitoring data of pH, conductance and rainfall showed that the results were consistent and pH value was most adjacent with correlation coefficient equal to 0.99. The conductance of samples collected by Andersen acid rain sampler was normally lower than Guotai acid rain sampler, so former was in possession of a better capability of resisting particles disturbance.更多还原
