, Mo2C interlayer was fabricated on the internal surface of C/C preform via molten salt deposition using ammonium paramolybdate as reactant. Then, C/C-Cu composites were prepared by pressureless infiltration. The influences of preparation temperature of Mo2C interlayer on the microstructure and properties of Mo2C interlayer and C/C-Cu composite were investigated. The results show that the Mo2C......

column with submerged zone (Col. T3) the values are 63%, 31% and 53%, respectively. The best nitrogen removal is obtained using Col. T2 with relatively low infiltration rate. Adsorption during runoff... applied to columns in a single repetition is denitrified during the draining period, suggesting that the draining period is an important timeframe for the removal of NO3--N. Infiltration rate controls......
:(38vol% Si Cp + 2vol% Al2O3f)/2024 Al composites were fabricated by pressure infiltration. Graphite powder was introduced as a forming filler in preform......

, matric suction and seepage force were taken into account after obtaining explicit solution of infiltration depth. Moreover, simplified analysis model under 3D condition was put forward based on identification and division of slope units, as well as modification of sliding direction of each column. The result shows that explicit solution of infiltration depth is of good precision; for the given model......
