　　The type and structure of 3. Ji'nan hood should be determined according to the nature and characteristics of harmful substance source, do cover the negative pressure or the face velocity uniformity, the exhaust volume (per unit time cover amount of air expelled from the Ji'nan smoke) should be to prevent the harmful substances to escape working environment through the principle of calculation can be used to determine the measured the data and empirical data, or through the model experiments.

　　4.济南排烟罩应能将有害物源放散的有害物予以捕
