But customer demand forecast has always been very insufficient, how to implement customer satisfaction strategy in commodity residence development to evaluate the development level gradually has become the matter developer concerned.
In addition, language established the water-injection well software (IWAS) using Visual C++6.0 , thus enhanced has matched the note working efficiency, Enhances the water-injection development oil field the development level and the management level.
Developing fracturing is the further development of fracturing technique in the recent years, through which optimally constitutes developing pattern system and fracture system of low permeability oil reservoirs in the purpose of improving producing rate and produced degree and decreasing the cost of investment, furthermore, improving the usable degree and developing level of low permeable hard usable reserves, and developing fracturing is an important components of low permeability oilfield developing plans.
Therefore how to establish the effective displacement radius,and the reasonable and economic well density with different permeability,it's important to raise the oil-water displacement efficiency,recovery efficiency factor and exploitation level of the low-permeable oil reservoir.
In this paper, based on analysis of present state of undergroun d space development in regions of Shanghai metro stations, some problems for enh ancing the level of development of underground space in region of metro station are presented.
Realizing its development status and researching its application have not only the theoretical significance but the great practical importance to improve the level of development of Chinese network software, particularly, the level of TMN, and will advance vigorously the evolution of information industry.
Because of the underdevelopment of the commodity housing market in our country, there are some unhealthy tendencies, such as low level of development, poor quality of housing, waste of resources, large deviation between housing function and its price, and so on.
On the basis of comprehensive analyses on the natural geographical environment, the socio-economic conditions in the peripheral area and the present status of tourism development in Yilonghu Lake valley, four major problems, i.e., low level of development, aggravation of water pollution, severe degradation of surrounding wetland ecosystem and the poor forest vegetation on the obverse slopes of the hills towards the lake, were pointed out, and corresponding countermeasures were put forward to develop ecological tourism in the area.
The authors studied the correlation between the physical development level and condition of psychophysiological functions in junior schoolchildren.
Their results show that the physical development level correlates with the condition of psychophysiological functions.
It is a common understanding in the civilized world that we should protect our environment from further damage, no matter upon what kind of political or ideological background this understanding is based or upon what kind of development level.
This paper applies aggregate data analysis to explore the relationships among the economic development level, the status of women, and the quality of life in developing societies.
Our analysis strongly confirms this hypothesis since the status of women in a society appears to rival the economic development level for explaining how good or ill is the quality of life enjoyed by its citizens.
Today, how to describe the urban sustainable developing level and measure the coordinated degree of environment, economy and society, has attracted more and more attentions of urban managers and researchers.
Through calculating, we have got the economic developing level, social developing level, environmental quality situation and the overall developing level, of Taiyuan from 1986 to 1995.
It is difficult to advance an exact developing level index of EDA due to its indieator system's complexity and disequilibrium.
Relationship between producer services developing level and urban hierarchy-A case study of Zhujiang River Delta
The paper takes the case of the Zhujiang (Pearl) River Delta (PRD), a developed region in China, to study the relationship between the developing level of producer services and the urban hierarchy.
This article discusses the major failure mode and the design principle of finite lifetime of roller chains on drillingrigs, and,in the light of the development level of the existing chain products on homemade rigs and the Standard GB 3638—83, recommends the methods for building up the horsepower rating table and rating chart and for determining the value of the fatigue exponent.The article also presents the methods for determining the design condition and design procedure for the various chains on the rig, offers...
This article discusses the major failure mode and the design principle of finite lifetime of roller chains on drillingrigs, and,in the light of the development level of the existing chain products on homemade rigs and the Standard GB 3638—83, recommends the methods for building up the horsepower rating table and rating chart and for determining the value of the fatigue exponent.The article also presents the methods for determining the design condition and design procedure for the various chains on the rig, offers the formulae for calculating the fatigue lifeof chains by different overloading performances.
This article introduces the applications and its present status quo of fine ceramics abroad. It is forecast that the fastest development ceramic materials will be those connected with energy development, optic facilities and functional ceramics related with tough ceramic reinforcement.
