A set of quadruply coupled equations (fluid flow, convection-diffusion, energy conservation and mechanical equilibrium) with a number of cross-couplings and coupled constitutive relations is formulated to quantify the multi-physics of oil displacement by CO2 injection, implemented into and solved by using FEMLAB. FEMLAB is the first engineering tool that performs equation-based multi-physics modeling in an interactive environment. With FEMLAB, the coupled multi-physics model can be solved simultaneously. The applicability of this model has been demonstrated through an example of simulations for a two-dimensional reservoir of size 1000 m×1000 m with one injection and one production wells. Model results illustrate the significant importance of the cross-couplings between individual (thermal, hydrological, chemical and mechanical) physics.

In chapter one, it compared letters with pictures and showed the importance of observation. In chapter two, it introduced the structure of human eyes and the course of vision. Chapter three introduced the basic key element of vision and the main theories of studying in vision aesthesia. In chapter four, it analyzed the principle of understanding the meaning of a figure according to the theory before, and analyzed the law of aesthetic. Then it explained how people feel the three-dimensional form and the movement, which have offered the theoretical foundation for creating more vivid image. It expounded the purpose and meaning of judging a visual figure in the fifth chapter, and introduced three general standards. It showed a method of judging the figure from different points of view in an example. Summarize to the full text finally, it point out the correct observation of vision image is one of the main ways for people's study, proposed the weak point of this text.
