For homotopic interaction, the saturation curve, molecular conformation vs ligand curve and certain correlation functions etc. are obtained by means of pure matrix algebra.

The factors of MOS transistor in the saturation region are analyzed, the mismatch models are optimized, and the model parameter extraction is done by least squares curve fitting method.

As time progresses, the water saturation profile becomes closer to the steady-state profile, which corresponds to the soil-water characteristic curve of the coarse sand.
