- 摘要：Though the Flood-Control-Projects along Yantze River and Jialing River in Chongqing may well improve the urban traffic and construction,it may change the river hydrodynamic characters.There may be two consequences,one is to reduce the size of cross section and the other is to change the river shape,such as the curvature radius.The phenomena of the local backwater and velocity variety are obvious,which result in some problems for the navigation: sediment,transport and so on.In this paper, the study object is the Flood-Control-Projects and Yangtse River and Jialing River,and the aim is to study the influence of the Flood-Control-Projects on the hydrodynamic state of the two rivers.Using the numerical technique,with the two rivers hydrodynamic model the flow field's change of river after completion of Flood-Control-Projects is simulated and the reasons caused by the change are analyzed.346|755|0更新时间：2023-11-28

- 摘要：In recent years, the problem of fouling on UF membrane mainly centers on the aspect of organic fouling. The cleaning methods of jam caused by fouling of polysulfone UF membrane, the behavior of organic fouling and the elimination of contamination are studied using several chemicals. This experiment proves that NaClO, H2O2 and NaOH all have some effect on the removing organic fouling of UF membrane, of which the H2O2 has the best effect. Controlling the pH value of raw water can decrease the organic fouling of UF membrane. At the same time, a very good result can be gained in the elimination of organic fouling in a way of combining the water solution of NaOH/NaClO and NaOH/H2O2, which makes the infiltration water flux of UF membrane being restored to its initial value. Moreover, the mechanism of organic fouling formation of UF membrane is analyzed.775|6|0更新时间：2023-11-28

- 摘要：Both tenderees and tenderers attach much importance to contractor prequalification before bidding because it plays important roles for both and so far the Score Method has been widely used in our country. But the weights in the method are man-made, which may be affected by personality inevitably. In order to avoid this influence, this thesis will introduce another method based on artificial neural network. This thesis expatiates the principle of artificial neural network, and analyzes the characters of prequalification. Then, the author sets up the mathematics model. In the end, the author analyzes this method by an example.414|6|0更新时间：2023-11-28
