The laser-cladding layeron the alloy consists of matrix phase of over-saturation solid solution γ and complexhexagonal carbide M_7C_3. Under certain condition, with fast laser scanning speed, the oversaturation solubility of elements increases in γ, and the precipitation of the complexcarbide M_7C_3 decreases, so that the microhardness increases and the wear resistance de-creases. But at slower laser scanning speed, more complex carbide M_7C_3 may precipitate, andthe wear resistance may be improved. Therefore, it is believed that the principal factor in im-provement over wear resistance is the precipitation of carbide M_7C_3, while overmicrohardness is the over-saturation solubility of elements in matrix phase.

The result indicated that we can get stable homopolymer and copolymer emulsion with uniform size distribution, when the ratio of sodium polyether sulfovinate modified polysiloxane to sodium lauryl sulfate was two, the quantity of the emulsifiers ranged from 6% to 8%, the quantity of initiator ranged from 0.4% to 0.8%, the stirring speed ranged from 200rpm to 250rpm, the polymerization temperature was 80 centigrade degree. As for the copolymer emulsion, the more the TRIS content in the monomers, the larger the water contact angle of their films became, namely, the surface energy of the copolymer films increased with the TRIS content in the monomers. In addition, the glass-transition temperature of the copolymers ranged from high temperature region to low temperature region with the increasing of TRIS content in the monomers.

The results show that side force, lift and overturning moment obtained by simulation and by wind tunnel test are consistent. When train travels with certain speed, the aerodynamic force and overturning moment acting on passenger car running on bridge, embankment and flat will increase greatly as cross-wind becomes larger while those increase less when the train runs on cut. Under the condition of strong cross-wind, aerodynamic force and overturning moment acting on train traveling on bridge are the largest. So the train traveling on bridge tends to overturn compared with that traveling on other three kinds of railway conditions. Aerodynamic force and moment acting on train traveling on cut are the least.
