High temperature air combustion (HiTAC) is a promising combustion technology with the advantage of energy conservation and pollutant reduction. The main objective of the present research focuses on the control strategy of regenerative furnaces. The control strategy was based on a model where alternatively operation of burners is considered. According to the concept of HiTAC, air-to-fuel ratio and the switching time were settled as the key parameters in the control system. The basic concept of operating sequences of changeover valves was provided. It was shown that this method can be applied for the design of regenerative furnace control system.

Improving the quality and extending the service life of hot-forging dies were a great system engineering. There were many Influencing factors. In order to find the very measure of extending hot-forging service life one must systematically research on the working conditions, failure features and reasons from the theory and practice, mastered the relations of die materials among component, microstructure and properties, analyzed the whole process of dies in designing, manufacturing and using.

The dynamic performance and heat dissipation performance of automobile ECU radiator directly decides the working stability to each part of the ECU. In the paper the FE model is set up based on the structure. The steady temperature field and liquid-solid coupling temperature field is analyzed on the basis of ANSYS program of FEM. Tiptop temperature relatively error is 1.4%. Many projects are compared based on heat dissipation performance of ECU radiator. The temperature distribution and heat gradient are calculated. Some conclusions are reached to improve the heat dissipation condition.

How to keep local features of the mesh and adaptive simplification becomes the research hotspot. This paper proposes a mesh segmentation algorithm and an adaptive mesh simplification algorithm, based on quadric error metric of Garland, that can keep the triangle grid local features effectively. The algorithm introduces vertex slope as the weighted value of the basic quadric error metric. Experimental results indicate that the algorithm, not only inherits higher speed and quality of the quadric error metric algorithm, but also overcomes the shortcoming of uniform grid.

There are many arch bridges in China, such as masonry arch bridges, two-way curved arch bridges and ribbed arch bridges. Many years later, these bridges appear diseases. This paper analysis the reasons of the diseases and proposes many methods to repair these arch bridges. The main diseases of masonry arch bridge are arch ring fracture, sidewall ballooning destruction and concrete decency. The main diseases of two-way curved arch bridges are pier or abutment displacement, arch rib strength deficiency, cross direction connection deficiency and poor drainage of packing. The main diseases of ribbed arch bridges are transverse crack of deck, longitudinal beam crack. This paper proposes many methods to repair these bridges, such as grouting method sealing crack, bending carbon cloth, bending steel plate and adjusting dead load of arch ring. At last, by analyzing profoundly disease reasons of masonry arch bridge, two-way arch bridge and rib arch bridge which are used widely in bridge engineering and providing maintenance and reinforcement measures accordingly and providing reference for reinforcing bridges.

In this paper, a numerical two-phase flow model combining with the Realizable k-ɛ turbulent model for compressible viscous fluid is presented for the simulation the flow around a fixed-cone valve; and the equations are solved with the finite volume method. The free fluid surface is simulated by the VOF method. The function of the fixed-cone valve for energy dissipating is pointed out by analyzing the computed pressure field, velocity field and streamlines distribution. Compared with the experimental data, the simulating results show that the proposed model is reliable and can be applied to the numerical simulation of turbulence flow around a fixed-cone valve.

The Ni-W-P/Ni-B duplex coatings were deposited on AZ91D magnesium alloy by electroless plating and evaluating their structure, morphology and corrosion resistance. The duplex coatings were deposited in dual baths (alkaline hypophosphite-and borohydride-reduced electroless nickel baths). The coatings were amorphous in as-plated condition. Upon heat-treatment, they were crystallized and produced nickel borides. Thus, the Ni-W-P/Ni-B duplex coatings with good corrosion resistance properties were obtained in protecting AZ91D magnesium alloy and expanding their scope of applications.
