To adapt to the continuous improvement of rural power consumption level in the new rural construction,in particular,with the continuous development of the rural economy,the actual operation of the rural power network has emerged as the high loss of electrical power which leads to a greater cost of the electricity,lower power supply reliability,the supply voltage and frequency do not satisfiy with requirements,etc.Through analysis of a typical rural power network,from the overall planning of the transmission to distribution equipments(such as lines,transformers and reactive-load compensation devices),the author proposes some specific measures such as reducing power loss and improving the voltage quality and reliability methods.Through calculation for lines power loss rate and percent of voltage pass,the results show that the methods proposed by the author are effective.The directions to the development trend of the rural power network is given. 相似文献

In 《Building·Home·Thinking》, Heidegger sees the essence of building as dwelling, and dwelling is the unity of “one of the dead”, “sky”, “land” and “God”. While the building is to protect the united to make them preserved in its essence. Heidegger points out the fact that architectural technology alienation and the “rootless” status, which is embedded in forgetting “the significance of the existence”. However, the architectural thinking of starting point and the theme is “one of the poetic dwelling”, which means, as the starting point of the “mortals” locking up to degree of communication. Even, its “poetic dwelling” and “others” coexistence of conflict.If built symbolizes human existence , then , it is in the direction of poetic dwelling, at the same time, forgetting building activity occurred in the city-the historical background, so the “Earth” as the historical background in the search for meaning in the forgotten, thereby, the pursuit of the meaning of building still fundamentally is broken. 相似文献

According to existent problems on design and application of the cylindrical cam mechanism with the slide roller-follower, the one correct concept about profile design and pressure angle is presented. Based on this concept, the theoretical profile,practical profile,meshing surface equations and pressure angle formula of the cam mechanism are built up by using opp.rotation analysis and offset surface principle. This method is very simple and clear, and avoids the abstract analysing process in meshing principle. The mathematic models built by this paper can be used to design,manufacture and check this type of cam mechanism correctly, and also create conditions to make deeply meshing property analysis of this mechanism. 相似文献

In recent 30 years, the asset-backed securization is one of the most important innovations in the international finance field. It promotes the quick development of the capital market. At present, on the one hand most of the Chinese real estate development companies are lack of financial support, on the other hand, the inland commercial banks are facing great potential finance risk. In this paper, how to get rid of the current contrary situation by the financing mode of asset-backed securization is discussed. 相似文献

To set up a mechanical model of three point loading for the intellectual measuring equipment of cable tension, the cases for elastic support with two ends of hinged support and those of fixed support with consideration of the influence of the cable were systematically studied. The equations for the upper and lower limits of the cable tension T as well as those for the real measured values have been obtained. A more rational equation for online measuring the cable tension by “Three point Bending Method” has been derived through secondary measurement. 相似文献

As the MCP is NP-hard, an efficient approach to treating this problem is to design appropriate recurrent neural networks. We develop a new algorithm for the MCP, which can, to a certain extent, prevent the associated neural network from falling into local optimal points. The proposed algorithm incorporates nonlinear self-feedback into the SLDN algorithm and has distinguished dynamical characteristics. Simulation results show that the performance of proposed algorithm is statistically superior to the SLDN algorithm. 相似文献

Masonry buildings with R/C frame- shear wall in the bottom storey have been widely used in city construction, which include two kinds of lateral force resistant system. However, the seismic behavior of the building is poor. Based on the characteristics that the rigidity of the upper masonry structure is much bigger than the rigidity of laminated rubber bearings and frame structure. It can be referred to as system having a two degree of freedom. The dynamic behavior of this building is analyzed, the isolated vibration mode controls the response of system. The authors give apractical method for dynamical analysis to masonry building with frame structure in the first storey with laminated rubber bearings between the first and second storey , which submits efficient path to found applicable design means and to generalize interlayer seismic isolation structure. 相似文献

Over the past decades, the automotive sector in China has been characterized by the obligation of foreign manufacturers to enter joint ventures, transfer technologies, and localize production. Still, the Chinese automotive industry has remained dependent on foreign brands, capital, and technology. The advent of markets and supply chains for electric vehicles, however, changes the framework conditions for established foreign automotive firms in terms of competitive landscape and access to core technology components. This is mainly the result of political initiatives: Established automotive manufacturers are exposed to direct and indirect restrictions that influence their production of electric vehicles, their choice of suppliers, and their potential market shares in the future. This paper outlines multilevel bargaining processes of Chinese and foreign actors as they aim to maximize value capture in a fundamentally transitioning automotive sector. In contrast to the lead firm-centric focus of recent global production networks (GPN)-discussions, this paper argues that the determinants of how production networks evolve is first and foremost a question of the institutional environment. Focusing on power balances between state and firm actors in multilevel bargaining processes offers a way of explaining GPN-evolution in institutional contexts in which power concentrates in executive bodies and decision-making processes are often informal. 相似文献

Stock prices are different on a daily basis with small ups, small downs, or abrupt changes. While small fluctuations are typical according to economic theory and understandable to most investors, abrupt changes are unexpected and can be either harmful (if dramatic downward change occurs) to a society's economy (and investors) or beneficial (if vast upward change occurs) to a society's economy (and investors). We introduce the variance change point model (volatility change point model), and use it to analyze two stocks: Shanghai Stock Composite Indices and Shenzhen Stock Composite Indices from 1992 to 2002. The authors use a binary procedure combined with Schwarz Information Criterion (SIC) as in Chen and Gupta (1997) to search all the possible variance (volatility) change points exist in the sequence. Changes in both indices are successfully identified and their economic explanations are given. 相似文献
