The high velocity arc spraying technology and powder-cored metal threads were bi-used to repair the waste components, and the integration between coating preparation and materials formation to Fe-Al base intermetallic compounds came true. A new supersonic ion spraying technique, named bi-channel, bi-temperature, was invented to solve successfully the issues of over-melting, half-cooked and burned materials. The high-energy mechanical and chemical method with own property right was explored to solve successfully the issue, which the nano particles dispersed evenly and suspended stably in the solution. After perfecting the techniques the high-performance co-electrodeposition between the conductive matrixes metal Ni and the nonconductive nano particles carried out. The excellent nano anti-friction self-repairing additives was prepared to achieve elementarily the self-repairing on the worn surface during the equipment worked.

Because the photospheric temperature of carbon stars are less than 3000K and the temperature of rich-dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro-vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars.

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.
