2.5s is respectively less than between seasonable.
7. large-scale waste gas of pollutant emission test method according to claim 1, it is characterised in that the quality stream is measured
During examination, the temperature and pressure of waste gas are measured using temperature and pressure transmitter (31), and asked using The Ideal-Gas Equation
Obtain waste gas density size；
Exhaust gas volume flow is measured using effusion meter (32)；
According to the density and the volume flow of waste gas of waste gas, exhaust air mass flow is directly tried to achieve in multiplication.
8. large-scale waste gas of pollutant emission test method according to claim 1, it is characterised in that survey the particulate matter
Examination, Contaminant measurement, mass-flow measurement the data obtained Jing data-interfaces (4) are connected with computer (5), to receive and locate
