Multilevel Fuzzy Theory Evaluation of the Tourism Resources in the Three Gorges Reservoir

Complexity of mutual act and different sensation of different tourists are important factors influencing regional tourism resources evaluation. Fuzzy mathematic method can be used to up quantitative evaluation method on tourism resources evaluation. Taking Wushan Small Three Gorges as an example, the author carries out the evaluation of the tourism resources in the Three Gorges Reservoir. At the same time, the authors consider that five factors, such as improvement of the comunication of tourism resources, quickening the Steps of urbanization in reservior area, must be done well.     

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.     

Portable ECG Monitor Front- ended Design with C8051 F020

The electrocardiogram (ECG) signal is a recording of the electrical activity on the body surface generated by the heart frequency of which is weak and low. Many researchers devote themselves to get more perfect ECG in many ways. This article introduces the characterize of an ECG signal , then discusses the requirements for the sampling circuit of an ECG. Since there are some shortcoming in common design means, the authors give an effective circuit. The system is composed of a low-cost , low-power and high-performance MCU C8051F020 , amplifier AD620 , right-leg drive circuit ,communication circuit and power management circuit. Then software design is given which is used to sampling and filtering ECG signal. Levkov filter arithmetic and smooth filter arithmetics are used in this design. In the end , the authors advance a distributing and networking ECG monitor system.     

Tissue Culture and Rapid Propagation of Actinidia chinensis

It has been briefly studied and reported that Actinidia chinensis , one of economic woody plants, has been bred with the method of plant tissue culture. Aim at the shortage of traditional plant tissue culture ways which ignored the refinement and transplant of test-tube seedling, it strengthen the study to breeding and management of Actinidia chinensis seedlings before they grow up and become mature seedlings. Through our explore, the transplant survive rate of tissue-culture seedlings attain to about 85%.This study is the improvement to traditional breeding seedling means and it is helpful to the rapid propagation of those economic woody plants.     

Lighting Design of Chinese Traditional Buildings and Application of New Type of Little Power LED

This paper is a part of the research on the lighting techniques of the traditional Chinese buildings in Summer Palace,Beijing,which is a sub-project of the Municipal Research Project on the Correlative Techniques for Beijing's Sustainable Development(Y0604017040391).The work,which the authors took part in,on the most representative Chinese traditional buildings in Summer Palace,is taken as a case study on lighting design and lab simulated experiments and checked by practical result,illustrating a working frame for other similar lighting design works.     

Developing a Recognition System of Gun-code

Intelligent recognition system of gun code is designed , which achieves online recognition of gun code. We applied video camera to get image, and some special technique in this deformed character recognition. As well, we applied dynamic template matching to get a better result.     

Empirical Analysis of the Demand of Rail Freight Transport in China on Basis of VAR Model

With the rapid development of road and other transport modes in China, the railway freight transport is confronted with great challenge. So, the relations of rail freight transport, development of national economy and extension of railway become focuses. This paper makes a cointegreting VAR model according to the data from Chinese Statistical Year Book. On the basis of the model of the long-run and short-run equilibrium of rail freight demand are analyzed, The result shows that the rail freight transport in China has a stable and low elastic coefficient of income and a high but unstable elastic coefficient of supply in long-run. In short dynamics, the national economy is the first factor affecting rail freight demand and in the second term the innovation reaches a top point. Extension of railway has little effect on rail freight transport. The innovations from rail freight transport and railway extension has little impulse on national economy. Rail freight is the important factor affecting extension of rail-way with a third-term top, but GDP has a little impulse on it. Further analysis on the result and suggestion on policy are made.     

Study on Genetic Fingerprinting Technique of Microbial Communities

The 99% of all microorganisms in naturecannot be isolated by standard culture methods without conspicuous external characters to classify them morphologically. In addition, classification based on physiological or biochemical features are often fuzzy. Molecular techniques are used for uncultured microorganisms to explore the diversity of microbial communities and novel resources without the need of cultivation. DNA dynamics and cloning of PCR products obtained from environmental DNA is now routinely used to identify microbial populations in microbial ecology. For practical reasons the approach is not suited to study the complex dynamics of microbial communities in environment. Genetic fingerprinting techniques are better tools, which give complement for the traditional microbiological methods. The methods are rapid and relatively easy to perform, and they allow the simultaneous analysis of multiple samples, which makes it possible to compare the genetic diversity of microbial communities from different habitats, or to study the behaviour of individual communities over time.     

葡萄组培苗瓶外生根技术研究

采用不同种类和浓度的生长素诱导葡萄组培苗瓶外生根，并观察组培苗在不同处理基质、不同的温度、不同的生理年龄条件下生根的效果。通过优化技术参数，建立了葡萄组培苗瓶接生根的技术优化体系，结果表明，用浓度为0.3mg/L的IBA浸蘸处理的插条，在温度为27~29℃的环境条件下在基质珍珠岩上培养，瓶苗茎段的生根率可达85.5 %，移栽后苗木的成活率达98 %，相对于其他方法有了较大的提高。该技术的建立有助于实现葡萄工厂化育苗技术的商业化扩大。
