Under a definite gas state parameter and environment condition, the measurementdeviation was correlated with the sampling time and the flow rate.
并得出在采样气体状态参数和环境条件一定时，除尘效率的测定误差主要取决于取样时间及流量。

The statistical methods used are general statistical description (such as mean and standard deviation), repetitive measurementdeviation analysis, clustering analysis and multiple linear regression.
