By using the Detrended Fluctuation Analysis method, we study the long memory of the realized volatility and realized bi-power variation constructed from high-frequency intra-day return series of the Shenzhen stock index and its 14 component stocks in China Stock Market. We find that the realized volatility and realized bi-power variation exhibit significant long memory from one-minute to sixty-minute...
In order to explore the root causes of different housing prices in similar geographical location regions, this paper selectes High-tech Developed Zone in southwest and Feng Wei New Zone in northwest of Xi'an as two research objects, collectes commercial housing price samples of the main corridor connecting the central area in both zones, and extracts three influencing factors of housing prices: geographical...
Liaoning province, as the earliest industrial base in China, has been the major heavy industry center since the founding of the country and thus its economic development highly relies on energy utilization. Now confronted with the approaching exhausting of primary energy, the economic development of Liaoning province faces its bottleneck. With statistical analysis, this paper selected the panel data...
This study is founded on the basis of gravity similar rule, and the hydraulic model of waterfall channel in the bottom hole of Xiyagou's spillway is established. At the same time, experiments research on discharge capacity, outlet flow pattern and landscape effect of waterfall channel. Basing on examination, the discharge capacity of waterfall channel meets design requirement. And the waterfall channel...
There is no novelty in the ideas that genetic diversity are essential to scientific advance and the future of human society. Genetic diversity will play the fundamentally important role to in crop improvement and agricultural system. China is one of the origin countries of Asian cultivated rice, its rice genetic resources are richful. Base on analysis rice varieties from 25 major rice producing provinces...
The core area of Flower Lake in Zoige alpine wetland withers, the natural grasslands around the lake degenerate, and the number of pests and mice continues to grow. The moist marsh is under the progress of developing into marshy grassland, and the storage runoff and water source conservation functions of the wetland have been drastically weakened. In order to protect the marsh landscape of the lake...
The estimation of soil organic carbon(SOC) densities and dynamics is necessary to understand terrestrial carbon cycle and carbon budget. The relative research on the Tibetan Plateau was few and uncertainty of the SOC densities and dynamics. The dynamics of soil organic carbon and its fractions, including active, slow and passive pools, were simulated using CENTURY model in alpine meadow at Damxung...
For the water bloom of Xiaojiang which is a branch of the Three Gorges Reservoir, we discussed the flow characteristics such as the length of the waterback area and the mean velocity in section along the river of Xiaojiang during the water bloom period. It is helpful for the understanding of the relationship between the water bloom and the hydrodynamic conditions. And based on the under constructing...
In this paper, we have explored the relationship between carbon dioxide emissions and GDP growth both in US and China, and got some significant conclusions. The results showed that the total carbon dioxide emissions were large both in China and US, there are many differences between two countries. Although both the CO2 emissions growth and GDP growth of China were much higher than those of the US,...
Although China-ASEAN Cooperation in Banking Supervision has made many achievements, there are still some problems. Through establishing a game model of inter-countries cooperation in banking supervision and analyzing the strategy selection under different conditions. We can conclud that: countries with high financial openness in the China-ASEAN region are actively committed to supervision cooperation;...
Hydraulic project has multi-target constraints, cross-fields science, multiple departments cooperate of feature. According to these characteristics, the text presents connotation of knowledge management, features and framework of system in hydraulic project. The knowledge ontology model and definition of knowledge is core of the text which form and define knowledge base on meta-model. Mixing database...
The characteristics of the corrugated steel plate culvert (such as mechanics, applicability, economy, etc.) are analyzed and the Life Cycle Cost (LCC) approach is put forward to analysis the initial, maintenance and recycling cost of it. Then the total LCC of this type of culvert is compared to the masonry and reinforced concrete culvert. The results show that the LCC value is reduced compare to the...
This author firstly reviewed the analysis of the social welfare effect for forest certification under the partial equilibrium, then based on the general equilibrium analysis's angle, full considering forest certification's environment benefit situation, the author has analyzed the forest certification social welfare effect by the neoclassic model, and pointed out that so long as the gains by the trade...
A novel matrix converter referred to as a boost AC-DC-AC matrix converter is proposed. The basic configuration of the new topology and its fundamental principle are firstly introduced, the analytic expression on the function of voltage transfer ratio and duty cycle is analyzed, the method of design sliding mode controller is clarified. Finally the validity and feasibility of the new topology are tested...
With the rapid growth and development of China's economy, the hotel industry has correspondingly experienced extraordinary growth demonstrating different interesting characteristics of its spatial distribution geographically. The paper seeks to analyze these spatial characteristics affecting the dynamic system of tourism development based on the six dynamic indicator covering twelve influential factors...
360 vs. QQ war, which happened between September 27 and November 21, 2010, was regarded as “desktop nuclear war” in China's internet history. This paper analyzed web traffic data between October, 2010 and March, 2011, which were provided by Alexa, a web information company, on its web site, to study Chinese users' response to 360 vs. QQ war. Among all actions that 360 and QQ took in the whole process,...
Modularity production network is evolving in a paradox of knowledge diffusion and encapsulation. Then the problem of the dual relationships between knowledge stickiness and interface rules comes into being. The knowledge stickiness effect of modularity production network was studied based on the perspective of interface rules evolving by use of normative research method. The main standpoints were...
Knowledge talents result in more uncertainties. Traditional economic theories assume that every principal in the market holds enough information. Therefore, they can not directly describe the complex relations between organizations and their knowledge talents. The transaction of knowledge talents can not sustain unless the uncertainty and asymmetry of knowledge talent information have been scientifically...
When oilfield development comes to the end of waterflooding, the formation seeping features grows more complex. As a result, how to describe the variation of reservoir percolation characteristics comes to play an important role in making and adjusting a development plan. First, data processing methods for tested wells and construction methods for non-tested wells are used to interpret discrete single...
The income distribution reformation is always attracted much attention as a major problem in china. 2009 April, standing committee of state council issued the proposed to speed up the adjustment of income distribution on strengthening the guidance and implementation of the law, which means the new round of income distribution reformation started from 2006 was put on the agenda again. This paper start...
