1VERIFICATION OF MATHEMATICL MODEL FOR SEDIMENT TRANSPORT BY UNSTEADY FLOW IN THE LOWER YELLOW RIVER显示文摘Field data from the Lower Yellow River (LYR) covering a period of ten consecutive years are used to test a mathematical model for one dimensional sediment transport by unsteady flow developed previously by the writers. Data of the first year of the said period, i.e., 1976, are used to calibrate the model and those of the remaining years to verify it. Items investigated include discharge, water stage, rate of transport of suspended sediment and riverbed erosion/deposition. Comparisons between computed and observed data indicate that the proposed model may well simulate sediment transport in the LYR under conditions of unsteady flow with sufficient accuracy.JianjunZHOU BingnanLIN 2004International Journal of Sediment Research2004,19,4:2
2CGE Models and Tax Reform in China显示文摘Some domestic tax CGE models will be introduced and analyzied in this paper, followed by a summurization of the advantage and shortcoming in these works. Then the paper presents the areas for improvement of the domestic tax CGE model research including making the static model dynamic, incorporating the coordination of fiscal policy and menotary policy in model, improving the reliability of data collection and parameters evaluation, and adopting general acceptable softwares to solve them.JianjunZhou TaoWang 2004Journal of Systems Science and Information2004,2,2:0
