以往研究中多采用传统的”排放强度分档取值法”确定排放速率(详见1.3.

Theoretical studies based on past use more traditional "emission intensity stepper value Measurement" emission rate (see Section 1.3.1,3.2), the classification process emission intensity, emission section and feature selection value is determined, It is not clear, given the value of the emission rate and subsequent research has brought greater uncertainty.

In previous studies, the traditional "emission intensity differential value method" was used to determine the emission rate (see section 1.3.1, 3.2), the classification of emission intensity, the determination of emission range and the selection of characteristic values in this method, the theoretical basis is not clear, which brings greater uncertainty to the value of emission rate and subsequent research.

In the past, the traditional "grading method of emission intensity" was used to determine the emission rate (see sections 1.3.1 and 3.2 for details). The theoretical basis for the classification of emission intensity, the determination of emission interval and the selection of characteristic value in this method is not clear, which brings great uncertainty to the value of emission rate and subsequent research.
