摘要 本研究采用日本产NL-20型气溶胶采集器采集大气气溶胶,测定了其溶解液的pH值和电导率.并用PCA(Principal Component Analysis)方法分析了五种因素之间的相关关系得出,TSP的浓度与电导率和相对湿度呈现显著正相关性,而TSP的浓度与pH值和温度呈现出负相关. Aerosol sample is collected by NL-20 aerosol sampler and pH and electric conductor of its solution are determined. Using PCA(Principal Component Analysis) method, the correlation coefficients have been calculated.
