Abstract: In this paper, we tested the two points loading flexural performance of inverted arch CFRP reinforced RC beam with practical experiments, and contrastively analyzed the limit bearing capacity, deflection under loading, strain, cracking load, crack width and spacing between directly bonded CFRP reinforced RC beam and inverted arch CFRP reinforced RC beam. Then we explored an RC beam strengthen method with good reinforcement effect and good economy and which can be easily applied in practical constructions.

Abstract: This paper studies the application of CBR (case-based reasoning) in stone equipments variant design. As the actual design process and CBR process have collateral corresponding relation, CBR accords with the actual design process of deviser. The basic resolution model of variant design is established, and the instance of products variant design is presented. With the application of variant design principle, the design intensity will be lightened, and the design time will be shortened. Therefore the variant design accommodates the requirement of products diversification and client orientation.

Abstract: A six degrees of freedom half body vehicle suspension system is presented in the paper .The Back Propagation neural network algorithm and the Radial-Basis Function network algorithm is adopted to control the suspension system. With the aid of software Matlab/Simulink , the simulation model is obtained. A great deal of simulation work is done. Simulation results demonstrate that both the designed radius basis function neural network and the back propagation neural network work well for the proposed vehicle suspension model in the paper .

Abstract: Hot deformation behavior and microstructure evolution of Fe-32%Ni alloy were investigated when compressed at the temperature of 1000°C and a strain rate of 2×10^-3s^-1. The microstructures were analyzed using optical microscope (OM), electron back scatter diffraction (EBSD) and transmission electron microscope (TEM). The results show that the generation and development of dynamic recrystallization (DRX) can obviously refine the grains of Fe-32Ni% alloy and the DRX reached dynamic equilibrium when the strain was high. According to the TEM observations, the DRX microstructure can be categorized into three kinds: grains with low dislocation density, which are DRX nucleations; grains with low dislocation density around the grain boundary and high dislocation density in its interior which means that grains with dislocation density gradient and which are DRX grains in growth; grains with high dislocation density, which are fully work-hardened DRX grains.

Abstract: Low-alloy steel coupled steel bars is formed to ladder-framework by two parallel cold-drawn that’s they are longitudinal reinforcement wedding with short and band cold-drawn that’s low-carbon steel are transverse reinforcement. In this paper, study on its mechanical and technology properties. So, get suggestion model calculating formulas of crack width and stiffness are presented. The advantages of cooperating between coupled steel bars and concrete have been primarily accepted.

Abstract: This paper describes the concept of the construction of steelmaking shop, which is carried out as part of a modernization plan aimed at creating a 21st century environmental-friendly iron and steel works, designs the smelting reduction process of producing stainless steel crude melts in a 150 t converter and presents an outline of the equipment specifications and the conditions of operation, according to the blowing conditions of 185 t smelting reduction converter of No.4 steelmaking shop in Chiba Works of JFE Steel. In the future, a rational production system will be constructed by flexible selection of raw materials in response to changing stainless steel raw material prices and further improvement in productivity and quality, making the maximum use of functions of the equipment.

Abstract: A PLC-based multi-well automatic metering and remote monitoring system has been developed to improve metering accuracy, realize multi-well continuous metering and meet the needs of remote monitoring. A three-level management mode consisting of metering station, oil production crew and oil production plant is built. The metering station is used to control the metering order, monitor the working condition of oil wells and upload metering data to oil production crew through wireless module; the oil production crew is used to receive the instantaneous data from the metering station and upload the statistical data to the server in the oil production plant; the oil production plant is used to browse and manage the data from every oil production crew through internet and the website of oil field data management system has been developed based on B/S frame. Field test shows that this system can accurately meter and analyze oil production data, generate needed reports and graphs with the functions of automatic metering, remote transmission, data analysis and queries.

Abstract: In this paper, the effect of manufacturing errors (MEs) on the performance of 1×2 optical power splitter is investigated in details. The ME, which is assumed to take regular shape, is considered in each section of the device. Simulation result shows that ME has a significant effect on the output power especially when it occurs in S-bends.

Abstract: Sensor technology and computer control technology are applied to automobile fuel consumption testing in the automobile industry developed countries, the function and precision of the test are developing and perfecting continually. In our country, automobile fuel consumption test mainly applies ordinary consumption test devices, that test item are single-chip, which is applied for testing the flow of time. The display of method mainly based on the pointer instrument and partially on circuit control, so the maintenance and reliability of the test does not excellent. We do research and develop the intelligent one which is called quick testing instrument for automobile fuel consumption, which applies sensor technology, computer control technology and advanced instrument technology, that can be applied for the testing for automobile fuel consumption and data show. It can improve the measurement precision of automobile fuel consumption and degree of automation, with the down cost as high cost-effective consequences. The test instrument can be used for testing instantaneous fuel consumption, average fuel consumption and accumulative total consumption of gasoline engine and diesel engine.

Abstract: There is so much exhaust steam in a boiler system that it causes great heat energy waste. A new type auto-reclaim facility of boiler exhaust steam heat energy is designed based on hydrokinetics, pyrology and automation. The new type facility is made up of water-gas injection pump, liquid relay deoxidization tank, field electrical control cabinet, instrument cabinet, loop booster pump and remote consoler. When the facility is used in the boiler system, not only can it reclaim the exhaust steam heat energy but also the whole steam and working medium. The facility is of high reliability under intelligent control and mechanism architecture. The facility has been applied in more than thirty China Petrochemical manufactories. This patent facility receives the high praise in the field of boiler steam heat energy reclaim.
