The experimental results show that microwave sintering promotes the densification of green compacts with higher heating rate and reduced sintering cycle. The sintered relative density of 99.8% can be achieved during microwave processing under appropriate conditions. In addition, microwave sintering improves the uniformity and homogenization of W grain size, and yet leads to growth of W grain. Fe sintering aid degrades the microstructure uniformity and further coarsens W grains. The present investigation demonstrates the feasibility of applying microwave sintering technique to consolidate W-Cu composites and its promising outlook in reducing production cycle and cost.

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.
