the equation Y=b0+b1X+b2X2+b3X3 describles the relation between the droplet drift and the distance downwind well,and the coefficients in the model have a clear practical meaning. This paper also advances an effective buffer zone width in 2,4-D butyl ester aerial application.
The effect of droplet size on deposition of chlorpyrifos on rice leaves was also dis-tinct. Under leaf incline angles of 90°,60°,30° and 0°,the deposition of chorpyrifos spraysolution with small droplets(VMD 149.5μm)were 1.5,2.1,3.3 and 5.5 times more thanthat with coarse droplets(VMD 233.7μm),respectively.
Based on Gamma distribution model of fog drip size derived from the empirical relation of visibility and water content for advection and radiation fogs, the relations between radar reflectivity factor and fog visibility or water content are proposed.
The film possesses high photocatalysis performance. When TiO2/SiO2 composite hydrophilic film is surrounded by vapor, the surface of theglass which is coated by TiO2/SiO2 composite film maintains transparence and there is no adhesion of fogdrop on the film, it is anti-fog.
A series of scientific data from previous experiments were analyzed and it can be draw the conclusion that in most experiment the diameter of fog droplet peek value is between 3 to 7 μ m,coincided to the medium - infrared.
An overall probing of fog was made from central area to borders of the city ofChongqing in the winters of 1989 and 1990.By use of 119 fog droplet spectra taken from fivesevere events for the urban region,a study is performed of fundamental characteristics of thedroplet size distribution,evolution and main contributing factors,with realistic interpretationsgiven to two of the events under consideration.
The diameter and height of spray dryer could be calculated by combining these analytical equations with the analytical equations from references for calculating the fog droplet movement time in the laminar region and the turbulent region.
Fog drip under the vegetation was three and a half times greater than the annual precipitation.
During the study period, 34%, on average, of the annual hydrologic input was from fog drip off the redwood trees themselves (interception input).
During these periods, there is no surface resistance to evaporation because the bog has been wetted by fog drip, and although the latent heat flux dominates over sensible heat (average β = 0.8), both are small.
Fogwater, fog drip and rainwater chemistry were examined at a tropical seasonal rain forest in Xishuangbanna, southwest China between November 2001 and October 2002.
The mean pH of fogwater, fog drip and rainwater were 6.78, 7.30, and 6.13, respectively.
