GIS and the fundamentals and methods of geostatistics were applied to regionalize the spatial distribution pattern of Available Potassium, Available Phosphorus, Available Nitrogen and Organic Matter in Jinghe Basin. The results showed that: 1 It is clearly founded that the spatial heterogeneity of the soil available nutrient in Jinghe basin, and the human activities had seriously impacted on the spatial...
In order to investigate the retardation of water evaporation by single and mixed monolayers at air/water surface, surface pressure (pi)-time (t) isotherms, specific evaporation resistance (r)-temperature (T) curves had been used to describe the properties of monolayers made from single monolayers of 1-hexadecanol (C16OH) and mixed monolayers of C16OH and nonionic surfactants. The results showed that...
In order to investigate abilities of anti-environmental interference of water evaporation retardants, a new kind of water evaporation retardants composed of 1-hexadecanol and nonionic surfactants was prepared in this paper, and effects of environmental factors on retardation of water evaporation of mixed monolayers were studied. The results showed that in comparison with monolayers of single component,...
