Advances in Study of Natural Antibacterial Medicines

This paper introduce the advances in study of antibacterial effects of natural medicines in the past ten years.The antibacterial components of natural medicines mainly include flavonoids,terpenoids,alkaloids,lignans,phenols,etc..This paper is intended to provide data reference for the research and development of new natural antibacterial medicines.     

Hydrolysis and Condensation of Silane Agent for Metallic Surface Treatment

Novel surface treatment technique by silane film is developing for metallic anti corrosion and coat improvement. The key points, hydrolysis and condensation, for the stability of the Silane agent(SA) solution is investigated, and the effective factors of stability for silane agent solution and the relative rule are discussed. It is found that stability of SA solution is related to the temperature, pH, solvents, SA concentration and additive by studying the state of the solution and the conductivity-time curve of SA solution. Meanwhile, controlling factors and improving methods for SA stability are proposed to guide the practical application of metallic surface anti-corrosion treatment by SA.     

Analysis of the Sediment Development and Trend In Jinshajiang River Drainage Area

Jinshajiang River, which has a drainage area of 485,100 Km 2, average flux of 142.9 billion m 3, and soil conveyance of 247 million t/a, is the largest branch of Changjiang river. It is also the largest soil resource of the Three Gorges reservoir and upper reach of Changjiang River. To research the development and trend of Jinshajiang sediment not only has a relation to Jinshajiang water resource strategy, but also has important meaning to control the silt in Three Gorges reservoir and the Changjiang water resource development. The paper statistically analyses the flux and sediment conveyance of the Pingshan station, which is the primary hydrological station in the Jinshajiang River Drainage Area. Through several non-parameter statistical methods such as Spearman order correlativity check, Kendell order correlativity check, and linear regression check, the paper concludes that the sediment evolvement trend of Pingshan station is not distinct.     

Reasoning Method Based on Motorcycle Design

According to the needs of setting up a professional system based on motorcycle design,the CBR(case based reasoning) and RBR(rule based reasoning) methods are introduced.After discussing the difference between the two kinds of reasoning,a method of integrating them into the motorcycle design flow is put forward to realize the design reusable technology and improve the design efficiency,by using the CBR in the step of selecting the similar motorcycle and the RBR in project's modification according to correlative rules.     

Research on Financing Plan for International Cooperative Project in Housing Industrialization

Housing industry is a prop industry with great potential, but it is restricted by shortage of funds. So it is necessary to probe the financing system of housing industrialization in China. This paper puts forward a financing plan for the international cooperative project in industrialized housing in Chongqing. Furthermore, it investigates the concrete financing system of the whole housing industry.     

Control of Sweeper and Anti-jamming Measures

Sweeper is a machine, which can clean up rubbish on the road surface with functions like drizzling, sweeping and sucking rubbish. Aiming at control of sweeper, the author introduced analyses on the theory of software and hardware of the system and their design using single chip computer (8752BH) as the core of control system. At the same time, the authors expatiated some anti-jamming measures, discussed the measures from the points of restraining electromagnetic noise, hardware and software anti-jamming to enhance the reliability of the control system.     

Real-time Vehicle Scheduling

The traditional scheduling for vehicle is option in the fixed network. But it can't satisfy the real time environment. The demand of order is changeable and uncertain in real environment. It is convenient for scheduling transforming it into static data, but can't get the advantage on time. This paper proposes a real time vehicle scheduling on the study of traditional scheduling and discusses the model structure and the key technology for the real time system that establishes the base for develop teal time system.     

Model of Information Integrating in CIMS Based on the Object-oriented Method

Information integrating is the most important key to CIMS,which is the base of the function integrating and all others.Because of so many kinds,so complicated structure,so many different sources and uses that the information in CIMS has,it is necessary to build a popular Information Integrating Model. The model of information integrating in the thesis bases on the enterprise model,which is presented by ISO(International Organization for Standardization).According to the object-oriented method,the process of modeling begins with classifying the information,and then describes the definition of the attributes and the structural relation of those objects. By means of the idea of Encapsulation and Inheritance,the destination of information integrating can be arrive and the model of information integrating can be set up. The model which is based on the share information is helpful to finish the function integrating and the whole CIMS' construction. Moreover,the system which is developed following such program can be reused for many times and the developing circle of CIMS can be apparently shortened,too.
