Issue date:March 15, 2011 Publication year:2011 Pages:98-103 Language:Chinese ISSN:02588013 CODEN:ZDGXER Document type:Journal article (JA) Publisher:Chinese Society of Electrical Engineering, Qinghe, Beijing, 100085, China Abstract:The motor of bulb tubular pump unit, embedded in the enclosed bulb, has bad operation environment and requires better cooling facilities. Non-uniform air-gap leads the motor's temperature uneven, causing local temperature over high. The influence factors of non-uniform air-gap were analyzed. The motor's temperature and ventilation velocity distributions with non-uniform air-gap were calculated. And the motor's temperature rise was analyzed. The relation between required ventilation quantity and air-gap's non-uniformity were presented by calculating several examples. The results show that, when the motor has non-uniform air-gap, there is more heat value and less ventilation quantity with small air-gap. Therefore, the motor's temperature increases in large extent. In order to keep the temperature normal, more ventilation quantity is required. Compared with uniform air-gap, ventilation quantity increases by 8.1%, 15.1%, 24.2% and 33.7%, when the non-uniformity is respectively reached 5%, 10%, 15% and 20%. The conclusions can be used to control air-gap's non-uniformity and ventilation system design. © 2011 Chin. Soc. for Elec. Eng.

Issue date:March 15, 2011 Publication year:2011 Pages:613-626 Language:English ISSN:10221352 E-ISSN:15213935 CODEN:MCHPES Document type:Journal article (JA) Publisher:Wiley-VCH Verlag, P.O. Box 101161, Weinheim, D-69451, Germany Abstract:Adding nanofillers to PLA/PCL blends to change their surface and interface properties can improve their phase morphology. Here the selective localization of CNTs and organoclays as the third component in the blend is studied. It is found that clay is selectively localized in the PLA phase and at the phase interface whereas CNTs are mainly found in the PCL phase and at the phase interface. With a reduced viscosity ratio of the blend matrices, the CNTs change their preferred localization from PCL to PLA. The effects of the different selective localization of clay and CNTs on the morphologies are studied. In addition, the crystallization behavior of ternary systems also shows a strong dependence on the selective localization of nanofillers. In biodegradable PLA/PCL immiscible blend systems, clay and carbon nanotubes present different selective localization behaviors. The former is selectively localized in the PLA phase and phase interface, while the latter is mainly dispersed in the PCL phase and phase interface. These two selective localizations can be used as powerful tools to design phase morphology of the matrix blends and to control crystallization of the component polymers. © 2011 WILEY-VCH Verlag GmbH & Co.

Based on the numerical solution of the model, the effects of ground thermal property parameters and ground water advection on the heat transfer characteristics of U tube GHE were analyzed, the results indicated that the increase of ground thermal conductivity and specific heat can enhance the heat transfer characteristic. At the same time, the exist of ground water advection is benefit for the improvement of heat exchanger between the GHE and thus can improve the operation efficiency of GCHP. The experimental validation shows that the model can simulate the heat transfer process of GHE and provide a theoretical base for the study of the heat transfer characteristic of GHE.

Issue date:March 2011 Publication year:2011 Pages:500-504 Language:Chinese ISSN:03722112 CODEN:TTHPAG Document type:Journal article (JA) Publisher:Chinese Institute of Electronics, P.O. Box 165, Beijing, 100036, China Abstract:We introduce symbolic representation for quantum circuit, and show how n-qubit circuit can be described as a control qubit symbolic vector and a lower-order controlled gate, instead of the representation of higher-order unitary matrix. We extend the loopless Gray code binary generation algorithm and propose n elements k position binary generation algorithm. Besides, a fast quantum simulation algorithm (FQSA) is presented, it divides a qubit state vector into several operand groups, each group is multiplied by the same unitary matrix, and then the output can be given quickly. In contrast to any other state vector based algorithm, FQSA requires less memory, and has an optimal time complexity. The experimental result of QFT indicates that FQSA is more time-efficient and it can provide more qubits circuit simulation under the same condition.

The sample and reagent arrangements were achieved by a syringe pump. The target metal ions were accumulated on the morin modified glassy carbon electrode surface, and the quantification step was performed by subsequent anodic stripping voltammetry. The key experimental variables relevant to the voltammetric measurement procedure were optimized. For a 100 s preconcentration time, a linear calibration curve was obtained for a concentration range of 1 to 125 μg L-1 with a detection limit of 0.41 μg L-1. The analytical use of the established method was assessed by applying it to the determination of cadmium in real samples and carrying out recovery experiments. The method was subsequently validated by comparing the results with those given by ICP-OES. © 2011 The Royal Society of Chemistry.

COFCs contain a wide range of chemical constituents which are closely related to the temperature of cooking oil. Among these components, hydrocarbons are believed to be among the most toxic. Dodecane is one of the principal hydrocarbons implicated. The paper deals with the experiments carried out in laboratory to clarify the toxic effects of COFCs, adding various amounts of dodecane to aquatic solutions in dishes containing the floating aquatic plant Salvinia natans. Inhibitory effects on the vegetative growth of S. natans, i.e. on the development of leaves and buds are reported in the experiments. The production of new leaves is significantly inhibited. The percent inhibition of growth rate (%) in the number of leaves produced is significantly correlated with the concentration of dodecane.
