摘要
通过对流量计的校准、校准流量的修正和真实流量的推导 ,归纳出等速采样流量的综合算式 ,并运用程序计算法进行快速、准确地计算 ,真正实现等速采样。又通过对采样体积计算公式的重新推导 ,使之更加准确。
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.
