Issue date:April 2011 Publication year:2011 Pages:128-132 Language:Chinese ISSN:10031243 Document type:Journal article (JA) Publisher:Tsinghua University Press, Beijing, 100084, China Abstract:Hydraulic performances of slanting inlet conduits of three pump shaft angles(15, 30 and 45) were studied by numerical computation of 3-D turbulent flow. Model experiments for the same conduits were also conducted. The results reveal that all the flows in the conduits are smooth and uniform and that hydraulic performances are excellent with small hydraulic losses. All the conduit designs can provide the pump impeller with good inflow conditions. As the angle decreases, the objective function defined by the conduit's outflow parameters increases, and the conduit loss decreases, while the hydraulic performance changes little. © Copyright.

The local existence and uniqueness of the solution are given by applying the contraction mapping theorem. Then we present some conditions so that the solution blows up in finite time. Finally, the long-time behavior of the global solution is discussed. We show that the solution is global and fast if the initial data is small and that a global slow solution is possible when the initial data is suitably large. © 2011 Elsevier Ltd.

The determinations were carried out successfully via the analysis of p-hydroxybenzoic acid hydrolysed from polyoxybenzoate in a KOH solution by use of high performance liquid chromatography. The polymerisation degree of polyoxybenzoate increased with the reaction time and temperature, in particular when catalysed. The maximum polymerisation degree was 27-6 under the optimised conditions. The determined mass fraction of polyoxybenzoate in composite coatings deviated greater than 10% from the theoretical values either blocked or not. This is possibly due to the incomplete inhibition of the sublimation of p-acetoxybenzoic acid, the precursor of polyoxybenzoate, during the fabrication of polyoxybenzo-ate based composite material. © Institute of Materials, Minerals and Mining 2011.

The changes of rice and wheat yield and soil nutrient under term fertilization in different years, the crop yield stability and the relationship between crop yield and soil organic carbon and nitrogen were analyzed. Results showed that during the period of long-term experiment, the yields of rice and wheat in different treatment plot fluctuated and varied greatly among different years affected by climate and other factors. From statistic results of long-term experiment, increased trends of the yields of wheat and rice were found among different years. The increasing trend of rice yield was more significant than wheat, and yield of wheat fluctuated comparatively larger than rice. Effects of organic manure and crop straw treatments on increasing crop yield were more significant than chemical fertilizer treatments. Yield stability of rice was higher than that of wheat, CV of rice was lower and SYI of rice was higher than that of wheat respectively. The highest yield stability was found in treatment MPK (Manure and fertilizer P, K), but the lowest of that was found in treatment MNPK (Manure and fertilizer N, P, K). Amendments of chemical fertilizer, especially nitrogen fertilizer may lead to decline of crop yield stability. Nitrogen fertilizer was the major factor of yield increasing, but may lead to lower stability of paddy ecosystem. Correlation between crop yield and level of soil nitrogen was more significant. Compared to dry season, yield stability and increasing of wheat was more significant in wheat season, indicated a higher sustainability of paddy soil ecosystem which may be improved with years of cultivation.

One CCD image can be obtained in a position, and the other CCD image can be gotten by moving the target or camera to a new position. The principle of the calibration method based on one-step movement is expounded. The geometrical relationship and the criteria that the camera axis is orthogonal to the target plane are proven when the CCD image is circle. Finally, the experiment results verify that the method proposed is effective, and the data of the internal calibration parameters of the camera is given.
