Agricultural drainage water sampling was conducted along ditch systems from 1st order to 5th order in Nongjiang River and Bielahonghe River during June to September, 2005. The spatio-temporal dynamics of nitrogen concentrations in agricultural ditch systems were analyzed. Results showed that there were higher concentrations of nitrogen in Bielahonghe ditch(More)
Four typical successional series in the marsh communities of Sanjiang Plain were selected to investigate the changes of their beta diversity. The results indicated that from the 'starting community' to the 'end community', which had the most and the least moisture level in the series, respectively, the similarity coefficient between each community and(More)
We report a new, novel and universal method to fabricate high-quality titanium dioxide (TiO2) nanofilms on different substrates by a solid phase growth process of ion implantation and subsequent annealing in oxygen atmosphere. Ti ions were implanted into fused silica, soda lime glass, Z-cut quartz, or (0001) α-sapphire by a metal vapor vacuum arc (MEVVA)(More)
