大气颗粒物二重源解析技术的方法改进

The method amending of improved-source-analysis technique of atmospheric particulate matter.

在二重源解析技术基础上,改进了扬尘对受体贡献值的计算方法,并对结果进行了验证.结果表明,扬尘对受体的贡献值在方法改进后有所下降,扬尘与土壤风沙尘对受体的贡献值之和,比方法改进前扬尘对受体的贡献值略低,这与推测结果完全吻合.

Based on the improved-source-analysis technique, the method calculating the contribution value of suspension dust on the receptor was amended and the results were tested and verified. The contribution value of the suspension dust reduced to some extent after the method amending, the sum of the contributions values of suspension dust and soil dust were lower than the contribution value of the suspension dust before the method amending. These were consistent perfectly with the results presumed.
