提出利用自动射线原理结合重量法的简捷便携特点的便携射线仪手工监测PM2.5的思路，平行比对了便？？携？射线法和手工重量法所测60组PM2.5浓度的监测结果，采用线性回归及T检验、F检验等理论分析了两者数据结果间的有效性和可比性。结果表明，便携式？射线仪监测结果与重量法监测结果之间有效可比且得到了两者间的线性回归方程；此外进行了20组数据的实样验证，换算值和真值之间相对误差在8%以内，因而确定了便携？射线仪手工监测PM2.5的可行性。

In this paper, a thought of using portable ?-ray instrument for manual PM2.5 monitoring by combination of ?-ray principle and gravimetric method was proposed. Monitoring data of PM2.5 concentration in 60 groups measured by the portable ?-ray method and manual gravimetric method were compared in parallel. The knowledge of mathematical statistics such as linear regression, T-test and F-test were used for analysis of availability and comparability between the data resulting from the two methods. The results showed that data from the two methods were available and comparable and a linear regression equation between them was obtained. In addition, sample verification of data in 20 groups was performed, with the relative error between equivalent value and truth value below 8%. Therefore, it was proved that portable ?-ray instrument was feasible in manual PM2.5 monitoring.
