Combining the technologies of electronic currency and mobile communication, mobile banking services can not only make people in any time, any place handle a variety of financial services, but also greatly enriched the connotation of banking services. While people are enjoying the convenient, efficient banking services, the security issue becomes a focus of attention and a key to this business development. This paper outlines the development trend of mobile banking service, analysis its existing security measures and challenging problems, and puts forward a new solution to improve the safety of the mobile banking service. It is of significance to the development of mobile banking industry and the financial security of a country.

This paper presents an investigation on the mechanical properties of epoxy resin concrete (ERC for short) and its contrast test to cement concrete under the same conditions. It was observed that the strength formation time of ERC is very short and it has higher early strength, the strength formation of ERC has close relationship with temperature. It was found that under the same load, the deformation of ERC is larger than that of cement concrete, namely the toughness of ERC is superior to cement concrete.

The several-phased construction of highways and asphalt pavements should be carried out in the following situations：the foundations are made of soft soil or low-quality soil, the filling and digging of the foundations are replaced frequently, the traffic calculations are not accurate, and the fund of the initial phase is insufficient. The design of several-phased constructions can be the basis of remainder life concept according the regulations drew up by America Asphalt Association and combined the regular computing process in our country.

With the continuous development of science and technology, the method of using the pre-stressed carbon fiber on the concrete structure, in particular on the bridge structure has become a research direction by the domestic and foreign scholars. In this paper, it has done the long-term test for the civil carbon fiber in the library on the base of the research of reinforced concreted beams with pre-stressed CFRP plate, and has observed the slip of the carbon fiber fixed on the side of the tension anchor. The results showed that: when put 50% of the ultimate stress of the carbon fiber on the carbon fiber, under the action of long-term tension, the variation of carbon fiber and the slip of the carbon fiber fixed on the side of tension anchor can all achieve intended purpose of the experimen ,which provides the theoretical data on the long-term performance research of the civil carbon fiber reinforced on the concrete structures.

This paper is mainly focused on the structure characteristics and the flaws of existing studies of CRC+AC composite pavement, mechanics theory and finite element method are applied to establish CRC+AC composite pavement finite element models based on crack pattern, the critical load position of CRC+AC composite pavement is found out under different crack spacing, and cracks on the AC layer extended mechanisms have been studied. The results show that: critical load position may appear in the horizontal cracks in the middle of the edge and vertical of the central free edge; in the long-term effect of traffic load, AC layer surface because of traffic loads, temperature effects, quality of construction, materials, aging and other factors produce longitudinal and transverse cracking. CRC layer transverse cracks in the bottom layers of the corresponding region AC will also have cracks, and finally forms reflective crack on the AC layer surface.The results can provide a basis for rational design of CRC+AC composite pavement.
