The effects of nitrogen(N) availability and tree species on the dynamics of carbon and nitrogen at early stage of decomposition of forest litter were studied in a 13-week laboratory incubation *** litter samples including needle litter(Pinus koraiensis) and two types of broadleaf litters(Quercus mongolica and Tilia amurensis) were collected from a broadleaf-korean pine mixed forest in the northern slope of Changbai Mountain(china).Different doses of N(equal to 0, 30 and 50 kg·ha-1yr-1, respectively, as NH4NO3) were added to litter during the experiment *** litter decomposition rate expressed as mass loss and respiration rate increased significantly with increasing N *** mass loss and cumulative CO2.C emission were higher in leaf litter compared to that in needle *** dissolved organic Carbon(DOC) concentrations in litter leachate varied widely between the species, but were not greatly affected by N *** of the N addition rate, both N treatments and species had no significant effect on dissolved organic N(DON) concentrations in litter *** 52.78% of added N was retained in the *** percentage of N retention was positively correlated(R2.0.91, p<0.05) with the litter mass *** suggested that a forest floor with easily decomposed litter might have higher potential N sink strength than that with more slowly decomposed litter.

第2.届中国控制与决策会议

作者： Ping Guan 1 , xiao-he Liu 1 , Ming-hui Li 1 , Li Xue 1 1. School of Automation, beijing Information {2. & technology university, beijing 100192

Arc furnace is the typical complex controlled system with three-phase strong coupling, high nonlinearity and uncertainty. The control requirement of arc furnace is also very strict. The direct adaptive output-feedback fuzzy control is presented. It is applied to electrode regulator systems of arc furnace, and the detailed design procedure of the adaptive output-feedback fuzzy control system is given. The state observer is designed to solve the immeasurable state. The adaptive fuzzy control is utilized to approach the uncertain term of output-feedback control. The adaptive law of the fuzzy rulers parameters is derived by Lyapunov function. The results of simulation show that this proposed control can restrain the external disturbances, and obtain much better dynamic and static characteristics.
