The surface energy balance drives both evapotranspiration (closely linked to the CO2 flux) and sensible heat flux. By providing direct information on heat dissipation efficiency, surface temperature appears to be a key variable. In particular, a lot of work has been conducted on estimating ...
The surface energy of a solid surface can be interpreted as analogous to surface tension in liquids [49]. In mathematical terms, it can be defined as the reversible energy required to create a unit surface area at constant pressure and temperature and is represented in force/length (eg. mN/...
W-interaction energy between 2 neighboring molecules. It is a negative value. Conclusion ∵z_b>z_s∴E_b<E_s 2.3 Ostwald Ripening 现象:溶质中的较小型的结晶或溶胶颗粒溶解并再次沉积到较大型的结晶或溶胶颗粒上 。原因就是系统表面能。 固体也可以有表面能,所以可以按照上面表面能的知识来解释。 {\bo...

Quantitative knowledge of the surface energy balance is essential for the prediction of weather and climate. However, a multitude of studies from around th
the temperature pattern closely resemble the 100 and 400kyr amplitude modulation of precessional insolation variations at low latitudes. This implies that, to a great extent, variations in surface-ocean temperatures are a direct response to low-latitude insolation forcing by eccentricity, and not just...

is the characteristic of a surface. They must share some of the interaction energy with the neighboring molecules. Hence, thesurface free energy, γ, represents the rate of change of the Gibbs free energy of the system with respect to the area, A, at a constant pressure and temperature[1]...
