REAL-TIME MEASUREMENT OF STEAM HUMIDITY BY MEANS OF LIGHT SCATTERING
光散射法实时测量蒸汽湿度

Some important improvements of measurements for steam humidity by means of light scattering are proposed. Extinction coefficient of spherical particles is calculated with Mie's theory and, in accordance with the distribution of water droplets, the average extinction coefficient is calculated. The error is modified for forward scattering. The estab- lished measurement system can measure steam humidity and average diameter of water droplets simultaneously.
