A Single Circular with Equal-rate on 4 Points Sampling Method and Its Application in Production

Based on the viewpoint that the point of the average flow-rate at which the gas containing dust glows in the pipeline is that of the average value of dust concentation, a single circular with equal-rate on 4 points samoling method is presented to measure the concentration of the dust gas with wider range of distribution of concentration and disconcentration in the article, which gives illustrations to show its application and effect in production.
