Using the water-balance method, the authors studied the water consumption of tomato (Lycopersicon esculentum Mill.) and the relationship between evapotranspiration and water surface evaporation measured with 20?cm pan.
      
The accumulative value of evapotranspiration is approximately equal to the accumulative value of water surface evaporation measured using 20?cm pan.
      
Evaporation may be approximated using the mean monthly pan evaporation or free water surface evaporation data.
      
It was also established that there was a corresponding increase in open water surface evaporation during this period.
      
  water evaporation
It has been shown that fast removal of the water (evaporation in this case) from the protein-water system is crucial for the protein to stay in the nonequilibrium state.
      
A mechanism of water evaporation is found to be associated with surface electromagnetic waves, which break hydrogen bonds in the high-frequency (≈3×1013 s-1) field of the laser.
      
A transport-reaction model of single particle was proposed, which considered the water evaporation from the surface of droplet and the reaction at the same time.
      
A positive correlation was found between the weight of the water and the water evaporation computed from the hygrometer readings (r = 0.997).
      
Direct measurement of water evaporation such as by this technique may provide information on sympathetic reactions which could be utilized in both physiological and pathophysiological states.

  evaporation of water surface
Marsh evapotranspiration includes transpiration of marsh plants and evaporation of water surface.
      
The evapotranspiration of the marsh is one or two times more than the evaporation of water surface in growing season.
      
When the vegetation coverage of marsh is less than 10%, the daily evapotranspiration of marsh is close to the evaporation of water surface.
