| Abstract: | A combined formula of the constant speed sampling flow is induced through the calibration of a flow meter, the correction of a calibrated flow and the derivation of a real flow. A real constant speed sampling is obtained by a fast and accurate calculation using a program computing method. Finally,the quality of the fume and dust concentration data is improved by rederiving the formula of the sampling volume. |
