Get PriceThe freshwater in the atmosphere is divided into three types according to its existing form: 1) clouds in the sky, 2) fog near the ground, and 3) water vapors in the air. [] Different from water vapor, both clouds and fog are made up of tiny water droplets with a diameter usually ranging from 1 to 40 µm (the diameter distribution of raindrops in rainwater is usually ranging from 0.5 to 5 mm).

Get PriceThe vertical resistance is measured between the tripod electrode placed on the surface of the test sample and a metal plate placed under the sample, which works as the base electrode. For resistances lower or equal to 10 6 Ω, a constant voltage of 100 volts was used, while for resistances greater than 10 6 Ω, a voltage of 500 volts was used.
