Abstract: Dynamic Energy Budget software aims to identify simple quantitative rules for the organization of metabolism of individual organisms. It is always used to delineate reserves, as separate from structure. The energy density of Eriocheir sinensis was studied through DEB software in this paper. The results showed that Hepatopancreas energy density (32.17±3.77 KJ/g) was higher than gonad (23.19±2.86KJ/g), muscle (24.41±1.41 KJ/g) and carapace energy density (14.42±1.76 KJ/g). The difference between gonad (23.19±2.86KJ/g) and muscle energy density (4.41±1.41 KJ/g) of females and males was significant (P < 0.01), but not between muscle and carapace energy density (P > 0.05), and no difference between female and male individual in total energy (P = 0.887) at the stable stage. The linear relation between volume and weight of Eriocheir sinensis was gained by using regression analysis, V=6.104+1.117WW (R²=0.973, n=98), and the linear relation between total energy and dry weight was also gained, E=18.12DW-28.05 (R²=0.962 ,n=24).

Abstract: Polychlorinated naphthalene (PCNs) is similar structure and toxicity of dioxin (PCDD/Fs), it can be detected in the global environmental and biological samples. This paper introduces the main source of PCNs in the environment and environmental fate, sludge PCNs pollution level in 1.48~28.21 ng/g (dry weight), PCN-TEQs content is in 0.11~2.45 pg/g (dry weight), far below the content of other areas in foreign countries. The results showed that the sources of wastewater, sewage treatment plant is an important factor affecting the level of polychlorinated naphthalene pollution. Discussion on the distribution characteristics of sludge in polychlorinated naphthalene congeners, found that the distribution of PCNs congeners in all of the samples is largely the same, it is mainly two chloride and three chloro naphthalene, it showed that the pollution source has a certain resemblance. Research shows that, polychlorinated naphthalenes city sludge mainly comes from industrial pollution sources; in addition, an important source of waste incineration, burning heat treatment process is caused by polychlorinated naphthalene pollution.

Abstract: It has been widely believed that trust is the basis for on-line trading by both academia and practice. The process of f initial trust formation is a dynamic and repeated process. In the electric business environment, this work chose to research the first phase of the process, which is initial trust. The Writer established dynamic model of initial trust formation biased on theory of planned behavior with other theories, such as TAM and social exchange theory, after micro-analyzing this formation mechanism from. in order to confirming effectiveness of the dynamic model, the writer adopted empirical study, from which writer got an order of . From the result of empirical study, we got the strength order of main factors that can influence the establishment of initial trust.

Abstract: The paper analyze and comprehensive evaluate on the characteristics of the product life cycle in each link of the green product design and the life cycle, has obtained a series of design green design optimization method. In the choice of materials, this paper presented a method for the re-combination of recycled materials. In the recovery of the product it proposes the establishment of recycling system, and expounds the concept upgrade recovery. Design and manufacturing of green products and green recycling industry is the two most important link in green circular economic system, whether or not the coordinated development of the two sectors, is the key to the success or failure of the strategy of sustainable development.

Abstract: This paper analyses the content and process of human resource management information system in electric power enterprise, and will be required to set up a reasonable data into the database, according to the design principle of relational database for each database table to create a relationship between tables. Database query using a variety of optimization methods that greatly improves the query speed. System access mechanism ensure each administrative access authority. In the protection of information security, to meet the needs of users at the same time, System realize network management of electric power enterprise human resources, improve the efficiency of office.

Abstract: Through the analysis of the feasibility of using network technology and network technology in supply chain management system, the paper puts forward the design framework of supply chain management system based on the Internet of things, describes the key technology of the system. The application of Internet of things in the supply chain management system, that will realize the effective management of the whole supply chain; enhance the competitiveness of enterprises and the whole supply chain.

Abstract: According to the development trend of intelligent logistics in our country, combining database, communication, GIS (Geography Information System) technology, the paper study the key core technology of each module monitoring platform for vehicle monitoring system, and establish logistics transport vehicle monitoring platform that oriented small and medium-sized logistics enterprises, to realize the whole process of real-time monitoring for logistics and transport the vehicle from the warehouse to transportation, promote the informationization of logistics and transport.

Abstract: This paper discussed the scheme of process reengineering of the enterprise based on a small and medium enterprises, established ERP system of enterprise. This system uses powerful function of SAP R/3 to realize the design of ERP system. At the same time, this paper completed the overall design of ERP system in small and medium-sized enterprises; the design includes the overall structure of the database design and ERP management process. Through the test of practice shows that the test scheme can detect the presence of defects in the development process, providing security for the system reliability, this system meets the demand of small companies, and Bug also has been corrected.

Abstract: The paper applied Principal Components Analysis Method to analyze the PSC inspection results in the area of T-MOU and P-MOU. Set up the assessment of ship detention, the ships' main deficiencies of detentions were found out by the standardization of data processing and correlation matrix calculating. Provide the basis for shipping company to master the safety management focus and pass the PSC inspection.

Abstract: The paper combine cloud computing with knowledge management, and classify the knowledge management of enterprise information management system, finally the paper plan and design the overall architecture of enterprise management information system. According to the model of cloud computing, establish the cloud computing platform based on the construction of cloud computing and virtualization technology, in order to achieve the overall architecture of the management information system of enterprise that migrate to the cloud computing environment. This paper mainly introduced in the cloud computing architecture of enterprise management information system under the environment of cloud computing and implementation of knowledge management system.
