模型理论

Orienting directed from the theory of "interbed" put forward by Leake, based on the Terzaghi\'s effective stress principle, the principle of coupling groundwater flow equation and soil deformation equation is analyzed in this paper. And the land subsidence model coupled by three dimensional groundwater flow model and one dimensional soil deformation model was built.

Chapter 2: The chapter concentrates on the powerful instrument in studying the carrier transport properties—thermopower.. Starting with the base theory, the chapter discussed the thermoelectricity phenomenon in metal and semiconductor in detail, including the useful Mott formula, phonon drag effect (normal process and Umklapp process), abnormal thermopower in transition metal, two-band model, magneton scattering, and so on. To resolve the abnormal thermopower in low temperature, some theoretical models, such as the distortion of Fermi surface, resonant scattering, spin-bag model, were argued. Each of them has its limition.
