Abstract: The specification of standard body knitting underwear is designed according to the elastic of the knitting fabric, then the body fitting experiments are implemented on the sample clothing. The assessment has done for different elastic and different size knitting underwear by using mental scale. The specification of knitting underwear is revised to obtain the most suitable for the body fitting according to the result of the assessment.

Abstract: The current E-government system faced the problem of system heterogeneous and government information scattered. The traditional E-government system architecture can’t properly solve the problem of information islands because of its slow response, not easy to expand. This paper put forward system architecture based on SOA-ESB, and analyzed its principle. SOA (Service-Oriented Architecture) changed function into service, then the ESB (Enterprise Service Bus) provide the intelligent management and integrated to service, at the last, realize the electronic government affairs system integration and information sharing. The structure has characteristics of loose coupling, scalability and maintainability.

Abstract: The experiment of running-in properties of Double Circular-Arc has been done at power circulating testing. We have obtained rules of wearing at running-in stage. It may supply references to establish practical running-in course.

Abstract: In order to get the physical mechanics of gingko，hickory nut and their stalks, microprocessor controlled electronic universal testing machine (WDW-5E) was used to study the basic physical characteristics，pulling resistance and cutting resistance of their stalk in different harvest time and moisture contents. The impact of physical mechanics of cones and stalks on the picking process were analyzed and some concrete suggestions were put forward in the paper. This experimental study provides an important theory basis on designing and manufacturing different cones picking machine.

Abstract: The dynamic and uncertainty in service-oriented software(SOS) running environment , together with the autonomy and loose coupling of service resources，lead to higher workload and more complexity of exception handling. Aiming to guarantee the completeness of design for exception handling logic in service- oriented software, this paper proposed a formal description method which and the corresponding integrated verification method for exception handling logic. This method can guide the design quickly and efficiently construct exception handling logic model in service-oriented software, and validate whether all exceptions which explicitly declare in service-oriented software are processed

Abstract: The main problems in Chinese health food industry are the anomaly management, poor quality, and illusive advertisements at present. In order to regulate the quality and safety management of the health-care food，improve the brand image and reputation, enhance consumer trust and the competition in the international market, some suggestions are offered, which are band orientation, science addition and band innovation in order to ensure to execute brand strategy of health food fluently.

Abstract: The computing method of series traction mechanism of heavy machinery was studied. The scheme of its computing system with equivalent beam element was proposed. Based on this scheme, combining with secondary development of language of Matlab, the computing system was developed. Through comparing with the reslut of enity element with ANSYS, the computing system was verified. Beacause of the computing system developed, the computating efficiency is improved and the accuracy is ensured.

Abstract: A virtual piezoelectric vibration absorber with LR Parallel shunt circuit was developed to emulate the effect of a physical piezoelectric shunt damper. A controller was designed and the feedback structure according to the LR parallel shunt circuit was suggested by using the governing equations of piezoelectric shunt damping system. The inductor L and resistor R only “exist” as numerical representations inside the controller. The virtual piezoelectric vibration absorber can both eliminate the need for large inductor and tune circuit component parameters online to adapt to environmental changes. Therefore the two disadvantages of the physical piezoelectric shunt damper are overcome. The simulation results for a cantilever beam show the effectiveness of the Virtual piezoelectric vibration absorber for vibration suppression.

Abstract: In this paper, the noise of the rotor system is classified at first, and then the sound intensity experiment of the rotor system is conducted based on “two-microphone” method. Then the sound intensity contour maps were obtained from the measurement results. An investigation towards the relationship between the characteristics of contour maps and distributions of the rotor system on space was taken; the main noise sources of the engine were identified. The result provides guidelines for taking measures to reduce noise.

Abstract: In order to make the AC contactor’s working noise measured under enviroment with strong backgroud noise, a kind of noise detecting system is developed based on LabVIEW. Firstly,a vibrating signal is obtained by acceleration transducer;Then a noise value is figured out by using sound radiation efficiency index curve and A weighting curve. The results indicate that the measuring precision is 2dB. The noise detecting system meets the precision demand of noise detecting.
