Abstract:The multiple regression method is commonly used in the freight quantity prediction because of its simple and easy. How to establish the prediction model is a question worthy of being discussed, when we want to improve the precision according to different types of cities and independent variables. This paper analysed the character of industrial structure and discovered the rule of freight quantity and unit GDP freight quantity by the example of the city Yangzhou. The paper established two prediction models by the ways of multianalysis. The first model was the relationships between freight quantity and some independent variables including Social consumable retail turnover, GDP, the first industrial value of output, the second industrial value of output and the third industrial value of output; The second model was the relationships between unit GDP freight quantity and other independent variables including the scale of the first industry, the scale of the second industry and the scale of the third industry. Finally, the first model was proved to be more practicality and better on application in contrast with the second one in forecasting of freight quantity. © 2011 IEEE.

Abstract:The improvement of storage stability can reduce the segregation degree of modified bitumen to maintain its performance. In order to appraise the stability of the rubber powder modified bitumen and seek the methods for the improvement of its stability, tests were done to analyze the effect of microwave radiation and stabilizer on the stability of the rubber powder modified bitumen. The tests indicate that microwave radiation can improve the stability of the rubber powder modified bitumen, and when the dosage of the stabilizer is 5% of the rubber powder's quantity, the improvement on the stability is best. This paper can provide reference and guidance for the engineering application of rubber powder modified bitumen. © 2011 IEEE.

Abstract:All of geographical information system (GIS), management decision-making system (MDS) and automatic monitoring system (AMS) are important signs of the modernization of irrigation management. Although these technologies have been applied in some irrigation districts, their functions have not been generally integrated systematically. The authors, taking Dong Irrigation District as an example, developed an integrated irrigation management system including GIS, MDS and AMS. This study focused on the integration of all functions of GIS, MDS and AMS, such as management of basic spatial datum, prediction of water requirement of crops, decision-making of water supply, monitoring of irrigation pump stations and canal system, evaluations of management system, etc. In particular, evaluations of management system can provide important feedback information for improving irrigation management decision-making. © 2011 IEEE.

Abstract:The copolymerization of aniline and 5-aminosalicylic acid (ASA) in H 2SO4 solution was first carried out on a glassy carbon electrode using cyclic voltammetry. The spectra of IR and ¹H NMR demonstrated the presence of -OH group, -COOH group, and free radical in the polymer, indicating that the copolymerization of aniline and ASA took place under the electrolysis to form poly(aniline-co-5-aminosalicylic acid) (PAASA). The electric properties of PAASA are strongly dependent on the monomer concentration ratio in a reaction mixture and the upper switching potential used for the synthesis of the copolymer and the electrode materials. PAASA synthesized under the optimal conditions has a good redox activity from pH < 1 to pH 12.0; and in particular, only a 37.6% decay of the redox activity was observed after consecutive cycles from pH 4.0 to 12.0 based on cyclic voltammograms. The spectra of ¹H NMR revealed some unexpectedly magnetic properties of the deprotonated PAASA. This would be the primary cause why PAASA still holds a high redox activity at pH 12.0. The conductivity of PAASA is 0.58 S cm^-1 that is lower than that of polyaniline. © 2011 Elsevier B.V. All rights reserved.

Abstract:Co-doped Bi5FeTi3O15 thin films (BFCT-x, Bi5Fe1-xCoxTi3O15) were prepared using a sol-gel technique. XRD patterns confirm their single phase Aurivillius structure, and the corresponding powder Rietveld analysis indicates the change of space group around x = 0.12. The magnetic hysteresis loops are obtained and ferromagnetism is therefore confirmed in BFCT-x thin films. The remanent magnetization (Mr) first increases and reaches the maximum value of 0.42 emu/cm³ at x = 0.12 due to the possible Fe ³⁺-O-Co³⁺ ferromagnetic coupling. When x = 0.25, the Mr increases again because of the dominant Fe³⁺-O-Co ³⁺ ferromagnetic coupling. The remanent polarization (2Pr) of BFCT-0.25 was measured to be as high as 62 μC/cm², a 75% increase when compared with the non-doped BFCT-0 films. The 2Pr remains almost unchanged after being subjected to 5.2 × 10⁹ read/write cycles. Greatly enhanced ferroelectric properties are considered to be associated with decreased leakage current density. © 2011 Chinese Physical Society and IOP Publishing Ltd.

Abstract:A physical model test was adopted to study the characteristics of pressure fluctuation of reversible pumping system for irrigation and drainage by performance and cavitation test. Three measuring points were arranged in front-end of inlet passage, the back-end of discharge passage and outlet of guide vane. The results show that the maximum relative amplitudes of pressure fluctuation at front-end of inlet passage, the back-end of discharge passage and outlet of guide vane were 0.22, 1.10 and 1.20 respectively. With the increase of flow rate, the relative amplitude of pressure fluctuation increased in the front-end of inlet passage and the back-end of outlet passage, while the relative amplitude decreased first and then increased in outlet of guide vane. In the cavitation test the relative amplitude of pressure at outlet of guide vane increased when the intake pressure decreased to a certain value. The relative amplitudes of pressure fluctuation at the measuring points under different rotational speed varied with the lifting head in the same trends. For the same head, the relative amplitude increased with the increase of rotation speed in the front-end of inlet passage and the back-end of discharge passage, while no significant regularity was found in the relationship of outlet of guide vane and variation speed.

Abstract:The flow fields in a rotating impeller, near the volute tongue of a centrifugal pump, were measured by the 2-D PIV technique. At the flow rate of Q/Qbep=0.52, a counter clockwise recirculation flow existed on the blade pressure-side, when the blade was close to the volute tongue, a clockwise recirculation flow occurred on the blade suction-side. At the flow rate of Q/Qbep=1.0, a jet/wake flow existed at the exit of the impeller. The results show that the effects of the volute tongue on the relative velocity distribution are more significant at the low flow rate condition than at the best efficiency point.

Abstract:In order to directly obtain operation parameters, energy performances of large pumping stations were determined on the spot and analyzed. The discharges of water pumps were measured with five-hole probes and ADCP (acoustic doppler current profiler). Pump assembly head, input power of electrical motors and pump assembly efficiency were obtained through the data measured by measuring apparatus of the pumping station. The test precision of discharge and efficiency was analyzed. The efficiency conversion methods from model to prototype of the pump and the pump assembly were checked. The results indicate that the velocity distribution in cross section measured with five-hole probes can repeat very well, which stands for the actual axial velocity distribution in cross section. The test precision of the discharge and the efficiency could be controlled within 2.0%, which could meet the demand of field test of large pumping stations. The pump discharge and pump assembly efficiency are 11.8378 m³/s, 55.998% respectively when pump assembly head is 1.73 m, which meets the design demands of the pump assembly. The efficiency of prototype pump and pump assembly is obviously higher than that of model respectively because of size effect, and could be predicted accurately based on model efficiency by related suitable formulas.
