This indicates the transition from a diverse landscape of cultivated land, forest, shrub, and grass to a single landscape dominated by forestland in the watershed with the advent of the Post-Three-Gorges Era. For AI values over 90, landscape aggregation is evident. With increasing buffer ...
The heat and mass transfer associated with phase change phenomena are among the most complex physical processes. They have complexities such as non-equilibrium effects, interface motions, dynamic interactions of the interface, in addition to common complexities observed in single-phase convection [1]....
