摘　　要：用扩散采样法,吸收空气中的O_3,该方法测得的O_3浓度对臭氧发生系统产生的O_3浓度的相关系数为0.9895.该方法测得的空气中O_3浓度与自动连续监测结果符合很好.用七个相同采样器在相同时间、相同地点测得的O_3浓度的相对标准偏差为6%.The performance of an ozone diffusion sampler has been tested both in laboratory and in the field. The correlation coefficient obtained by plotting O3 concentrations measured by diffusion method vs, those occurred by the ozone generating system is found to be 0.9895. The concentrations of Oj in air obtained by the diffusion method are in good agreement with those obtained by ultraviolet photometry. The relative standard deviation for seven sets of diffusion sampler is found to be 6%.
