Abstract: The paper presented the development of free-form surface axis NC machining tool path optimization module. In the UG environment, have three-dimensional solid modeling to the surface, and then have the secondary development of free-form surfaces five-axis machining path optimization module through the UG/Open API and VC++6.0. This can realize NC processing path automatically generation and optimization after the three-dimensional modeling. Introduction

Abstract: A dynamic constitutive model is suggested based on dynamic triaxial test data of dam materials. Combining with construction of a high core rock-fill dam, several key issues, such as dam seismic response, dam permanent deformation, filter layer anti-liquefaction, dynamic strength of the core wall are analyzed by using 3-D dynamic effective stress analysis method. And some useful conclusions and regularity are obtained in the aspects of seismic response and anti-seismic properties. The analysis method and conclusions could be referred to the analogous engineering.

Abstract: The rock mass with polycrystalline aggregates is common geomaterial in civil and architectural engineering as well as hydraulic and hydro-power engineering. For this kind of geometerials, the study on the joint deformation parameters Kn and Ks and the calculation method are not enough so far. Focusing on the rock mechanics and engineering problems of columnar jointed rock mass related to Baihetan hydropower project, analytical models and numerical method based on 3DEC are employed to study the mechanical parameters. The joint deformation parameters Kn and Ks are back analysis using GRNN and the field data of load-bearing plate tests. The application shows that the calculation results are in good accordance with in-situ test results.

Abstract: The research of multi-campus university management, which is specific for a particular region, in particular to the Jiangxi Province of, is still blank. This paper traces the formation and development of multi-campus University in Jiangxi, carding the management status of multi-campus University in Jiangxi, analyzes the problems of multi-campus university development in Jiangxi, and on this basis, puts forward the measures of optimal management.

Abstract: The perovskite-like LaSrCoO₄ and LaSrCoO_3.6F_0.4 mixed oxides were prepared by the polyglycol gel method, investigated by using the XRD, TEM, BET, O₂-TPD and XPS methods, and used successfully for CO and C₃H₈ oxidization. The results indicate that LaSrCoO₄ and LaSrCoO_3.6F_0.4 mixed oxides have K₂NiF₄ structure. The catalytic activity of LaSrCoO₄ is better than that of LaSrCoO_3.6F_0.4, this is explained in terms of more mobile lattice oxygen, higher content of Co³⁺, more oxygen vacancies, smaller particle size and larger BET surface areas of LaSrCoO₄.

Abstract: The energy property of motorcycle’s clutch is considered as the research object, and the concept of the energy design factor is proposed, which is applied in the energy-optimizing design of the mechatronic product in the use stage. Based on the analysis of the energy-consuming information in the stage of product utilization, the energy-consuming model was established. In this context, this paper presents a systematic method to analyze the extractive mechanism and process of energy design factor. Finally the energy design factors was applied to the energy optimizing design of products.

Abstract: Compared to the China's urbanization and increased speed of rural workers’ group size, the author analyzes the reasons of social security system right absence for migrant workers from the perspective of both macro-and micro-urban, where dual urban-rural social structure decided by dual economic base is the basic reason that causes the social security system right absence. Besides, the existing social insurance system against those migrant workers and the weak awareness of migrant workers all have no adverse effect on the social security system right absence .

Abstract: With the development of medical services in all countries, medical and health accounting and its account system have been increasingly improved, however, the different statements of all countries when they adjust accounts for medical and health care have led to a lack of international comparability in the accounting results. In order to enhance the internationality of the domestic research on medical and health accounting and its account system, in reference to the scope definitions and standards of medical and health care in Health Care System (SHA) established by World Health Organization (OECD), this paper is based on China’s actual situation and has designed stock and flow accounting tables about illness of population, medical and health human resources and medical organizations, and manufacturing accounts and comprehensive accounts of medical and health activities, which are used for a comprehensive description of capital operation in medical and health organizations and production of medical and health activities.

Abstract: This article utilized the technological innovation theory to analyze the functionary mechanism of technology innovation on industrial competitiveness thoroughly, this was: The technological innovation enabled a state industry to have a more obvious superiority in the international market compared to the competitor, thus seized the bigger market share by reducing the operating cost of the industry, promoting the differentiation of the product, enhancing industrial productivity and the quality of the product and promoting the advancement of the industry’s internal structure.
