In order to explore optimization effects of RETC software and intelligent algorithms, including genetic algorithm, simulated annealing algorithm and particle swarm optimization, on parameters of Van Genuchten (VG)Equation for the soil water characteristic curve of urban green space, the soil drying curve of green space was obtained by using the tensiometer(More)
Titanium dioxide nanotubes were prepared and used as catalyzers for titanium dioxide nanotubes/UV/O3 to degrade humic acid. And the optimal parameters of titanium dioxide nanotubes/UV/O3 were investigated. The combined treatment showed the synergetic effect of photocatalysis and ozonation. When calcined at 400 °C, titanium dioxide nanotubes had the(More)
