By using of the symbiotic theory in population ecology, this article describes three symbiosis patterns between logistics enterprises in logistics park, parasitism, commensalism and mutualism. And then it analyzed the economic benefits of symbiotic logistics enterprises in the park by using the logistic model of ecology.
The area of integration is extremely broad, from the biosphere to human society, from local to global, from micro to macro, from object to subject where we all can find integrated phenomena or activities. For social integration, the integrating activities has subject. Broadly speaking, all the factors that consciously promote integration or put influence on the integration are integration subjects...
The thesis introduces entropy and dissipative structure theory of thermodynamics into the evolved study of compensation administration system. According to the compensation administration system's dissipative characteristics, entropy model is constructed on the basis of evolving compensation administration system. Through the quantization in terms of entropy, the thesis investigates the evolution...
Based on the design and construction for first-stage project of Changsha city NO.2 rack communication, engineering investigation technique of city tunnel engineering at complex karst area has been researched. It is simple and feasible to use comprehensive geological and engineering geophysics. In city karst area, these investigation methods can effectively identify underground target, which can comprehensively...
Hexane extracts of Potamogeton maackianus were fractionated using silica gel column chromatography under room pressure by antialgal activity-guidence. Ten fractions were obtained and three of them shown obvious antialgal activities. These three active fractions were further separated using gel chromatography (Sephadex LH-20). Then the active fractions Fr 3-5, 3-7 and 3-8 were obtained and their percentage...
Stainless steel is characterized by nonlinear stress-strain behavior, material anisotropy and different mechanical properties in tension and compression. As a result, it is necessary to define stress-strain relations of stainless steel precisely for the researches of mechanical behavior and stability of stainless steel member. This paper reviews the researches in constitutive relations models home...
The electric conductivity and the hydrogen evolution overpotential of the five kinds of cathode material were tested by Chronoamperometry and the Polarization curves method ,respectively. The electric conductivity of the cathode was as follows: The electrode of Ni/Fe > stainless steel>Ni>Pt/Ti>active hydrogen; The sequence of the cathode hydrogen evolution overpotential was as follows:...
This paper proposes a new logistics service mode-Logistics Service Supermarket for Enterprises (LSSE), viz. in the enterprise gathering places or economic development zones the logistics service supermarket is established to sale, lease, customize goods or service (such as lighting equipments, communication equipments and so on.) all day and night, which are the common goods used in all the enterprises...
Typical residential earth buildings in Southern Hunan area are of civil engineering structure, namely, adobe walls, wooden doors and windows, wooden roof truss covered by blue tiles. In this paper, the author made a field mapping and energy consumption survey on a typical residential building in Southern Hunan area, and conducted an indoor test on heat and humidity index in summer and winter. The...
With the promotion of the bill of quantity in china, the payment system which is based on the bill of quantity has raised even stricter requirement for the final settlement. Towards all the issues exposed in the final settlement process, the owner needs to find an efficient way to control the final settlement urgently. Interior control is a method which is used in the enterprise management so as to...
With the development of science and technology, people pay more attention on the using of resource. As wood is a not inexhaustible resource, many researchers want to find advanced methods which can reduce the waste materials and enhance timber utilization rate. This paper studied the intelligent numerical control machine for wood processing. Firstly, the requirements of wood processing machine were...
In this paper, we consider a manufacturer-supplier chain situation in which the manufacturer coordinates, e.g., supports, its supplier's innovation that can eventually lead to supply cost reduction. Developing some mathematical models, we show that sharing innovation cost has a better coordination effect, and manufacturer can share a part of innovation cost when the innovation coefficient is lager,...
Change the traditional management style and implementing informatization for construction enterprise is an important subject to promote the modernization of construction enterprise. This paper introduces the importance of implementing informatization for the construction enterprise based on their characteristics. And then an overall solution framework was proposed after summarizing research and practice...
Orthogonal cutting experiments of Fe-36Ni invar alloy are performed to investigate the influence of cutting conditions on adiabatic shear, which occurs in the process of chip formation of many materials. It is found that the cutting speed, cutting depth and rake angle all have influence on adiabatic shear and there is a critical cutting speed at which the adiabatic shear appears. By metallurgical...
Abstract-Improving the operation and management level of coal washing is an important way to enhance their competitiveness for modern coal washing enterprises. The article establishes the comprehensive operation optimization management system of modern coal washing enterprise that are the operation optimization management involving the all-direction, the whole process and full-time interval, and describes...
Data Mining can find out the hidden important information in mass data, whose main purpose is to help decision-makers to look for the potential relevance between the data, to find out neglected elements, and make decision based on these models automatically. This paper, based on the discussion of data mining, analyzes the framework of enterprise decision support system, designs the enterprise decision...
This paper analyzed the current development of electronic teaching materials, and probed into the restricting elements of the development: digital copyright protection, readability and multi-format support. Also, it reviewed the current readers' digital rights protection technology, and introduced the basic principles and properties of e-paper, and synthesized the advantages of the LCD screen and...
As a new developing economy in the 21st century, there have always been concerns about the scientific evaluation of a recycling economy. Based on the principle of material flow analysis and resource value accounting models in enterprise(s), through defining and tracking the value information of resource inputs, consumption, output and disposal in the production process, this paper builds a new evaluation...
Adsorptive effects of natural clinoptilolite (NC), HDTMA-modified natural clinoptilolite (HMNC) and CPB-modified natural clinoptilolite (CMNC) were assessed for the removal of Cr(VI) from water using stirring method. Subsequently, the surface characteristics of this three materials were analyzed by XRD and IR. Selectivity series deduced from removal effect of Cr(VI) were CMNC > HMNC > NC, and...
The differences and similarities of the leadership mechanism in the Sino-Norwegian bi-cultural teleworking teams are discussed in terms of two aspects: the basic leadership mechanism and the remote leadership mechanism. And then in the case study of a bi-cultural teleworking team in a Sino-Norwegian Joint Venture M, the problem about leadership mechanism in the bi-cultural teleworking team is analyzed,...
