Authors: Zhou Qi
Published: May 2014

According to the data on the geology, geochemistry, experimental analysis and production test of Liaohe Depression, the reservoir forming conditions of shale gas and oil were analyzed in this study. It is found that the Paleogene shale in the sedimentary basin has an extensive distribution, large thickness, high organic carbon content and wide variation scope of maturity of organic matter. It provides the material conditions for the formation of shale gas and oil. The shales have developed micropores and fractures, which provide favorable reservoir space for the free hydrocarbons. Due to the strong adsorption ability of shale, the gas logging abnormal of total hydrocarbons is usually present in the shale. A huge reserve of shale gas and oil resources is indicated. The shale reservoir usually has a high content of brittle minerals, so the fracturing technique can be applied for development. Therefore, the Paleogene strata in Liaohe Depression contain abundant shale gas and oil and the associated tight gas and oil resources. The shale gas and oil in the hydrocarbon generation sag and the surrounding shales and the interbed are the new deposits under the deep exploitation of Liaohe Depression. The shale gas and oil in the West Sag has the highest potential.

With the continuous development of social economy and urbanization in our country, noise pollution has become the fourth largest environment pollution in our country but water pollution, air pollution, solid waste pollution, which is the widest influence of traffic noise. In recent years, with the development of automobile industry and urban transportation, road traffic noise pollution in Harbin phenomenon is increasingly prominent, which seriously affected the People's daily life. Through detailed survey we found that the research on road traffic noise pollution situation in Harbin is very less, and part of the evaluation is not accurate. In this paper, firstly the characteristics of road traffic noise and noise evaluation index selection is discussed in detail. The xuefu road sections in Harbin city traffic noise and traffic noise pollution monitoring research in detail strict accordance with national standards. According to monitoring data of xuefu road traffic noise pollution source in time and space distribution analysis, the roughly the time distribution and spatial distribution of xuefu road traffic flow. By the overall analyzed monitoring data characteristic, the xuefu road traffic noise pollution is serious. According the previous analysis and research, the researchers find out the main factors influencing the xuefu road traffic condition, and we puts forward some countermeasures for the noise reduction. Through the study of this paper, that is to Harbin city xuefu road for the future of the road traffic noise monitoring and management work provide favorable basis, and it has good practical application value. It aimed at Harbin city road traffic noise control, urban planning and construction, provide theoretical basis for government decisions.

It is a key point that the surface machining feature plays an important role on machined surface morphology of high speed milling hardened steel. The machining surface morphology surface morphology plays an important role in the formation of surface roughness. In this work, the machining features are the target that find the law of effect on surface morphology. We experiment on the concave and convex surface respectively, find out the influence law of surface morphology with different machining features in the process of high speed milling hardened steel. The results show that. The residual height is lowest along a sinusoidal line, it is times in vertical direction, and it is the worst in the 45odirection. The curvature radius influence the residual height , but the effect in the convex surface is more significant than that of concave surface. By changing the Angle can effectively relieve the effects that the curvature radius influences on surface residual height.

In order to explore the effect of TiN and TiAlN coatings on tribological properties and efficiency of gear, TiN and TiAlN coatings were deposited on 45 steel and the surface of gears by Arc Ion Plating technique. The dry tribological behavior of the substrate and coatings were tested in a ball-on-disk tribometer. The microcosmic morphology of the wear areas were observed by scanning electron microscope and energy dispersive spectrum. The wear mechanism of TiN and TiAlN coatings were investigated to assess the performance of the coatings. The efficiency of uncoated and coated gear was obtained and compared at various input rotating speeds. The results showed that TiN and TiAlN coatings provide a significant decrease of average friction coefficients compared with substrate. The wear mechanisms TiN and TiAlN coatings are mainly abrasive and adhesive wear, accompanied with adhesive and oxidation wear. The efficiency of gear has been significantly enhanced after TiN and TiAlN coatings deposition.

With the development of high temperature protective material, thermal barrier coatings are used in the field of aircraft and industrial steam turbine. They have characteristics of complex structure and long-term work in high temperature environment, etc. Because of multilayer material physical properties mismatch, oxidation, interface roughness, creep stress and so on, the coatings system is easy to produce cracks, expand and link near the interface of coating during thermal cycling. By establishing I, II, III, IV four numerical models of crack fracture mechanisms, assuming that the thickness of oxidation layer is constant, considering the influence of interface roughness and material properties mismatch in the process of thermal cycling, it gets the results of residual stress field near the crack and the influence of the interface. Compared to the presence of defects, four kinds of crack failure mechanisms are analyzed. Energy release rate is calculated by the virtual crack closure method, which can conclude the cracks of I, IV tip stress concentration phenomena are obvious, crack II is easy to expand, due to the temperature load, crack III does not appear stress concentration phenomenon at the tip.

The purpose of this paper is to present the use of uniform design of experiments method and dynamic finite element analysis in improving the permanent deformation of an on-road bicycle frame which undergoes the drop-mass impact test. Firstly, four dimensional parameters of the bicycle frame are selected as the control factors to be improved. Then, uniform design method is used to construct a set of experiments. Each experiment denotes a specific design of frame. Next, for each experiment, the dynamic finite element analysis package ANSYS/LS-DYNA is employed to simulate the behavior of bicycle frame which undergoes the drop-mass impact test and determine the permanent deformation of the frame. Lastly, the best frame of all the experiments which causes the smallest permanent deformation is selected as the improved version of design. Compared with the original design which causes a permanent deformation of 8.458 mm, the improved version causes a permanent deformation of 7.467 mm. The rate of improvement is 11.7 %.
