干湿球法测量空气与烟气含湿量计算公式的推导和改正

Deduction and Correction of Equations for Measurement of Air and Flue Gas Wetness with Dry-wet Bulb Hygrometer

针对《环境监测技术规范》中烟气含湿量计算公式的不妥之处，设计了一套空气一水平衡饱和装置，通过这一装置推导出空气含湿量的计算公式，改正后的公式，免去了测量时另外测定烟道静压的步骤，具有足够的准确度．

By the use of a set of air-water equilibrium and saturate device,an equation for measurement of air wetness is deduced,in the light of the mistakes of the equation for meacurement of flue gas wetness in《Standard Mathods of Enviromental Monitoring Thchniqnes》.After correcting the equations, the measurement of static pressure is not necessary and the accuracy is good.
