Design considerations of minimum facilities for marginal oil and gas field development;

The present paper has introduced a simplified design project of sprinkler systems specifically purposed for recreational places.

Based on the analysis of the factors that influence the bearing pressure of the bond-wall of brick masonry and structural concrete column subjected to axial compression,this paper gives a simplified design method of the bond-wall subjected to axial compression—y-m line method,and makes out the corresponding chart for design and calculation as well.

From some aspects such as determination of power consumption and transformer capacity the simplified design method is introduced for temporary electricity usage in construction sites.

Under the conditions of simplification and assumption,a Markov model of BDAR(battle damage assessment and repair) effect on the combat effectiveness of aircraft is built,and the change trends of three types of combat effectiveness with BDAR is discussed,then the importance of BDAR to the combat effectiveness of aircraft is i.

So it’s necessary to set a series of stan- dard to guide the cultural facilities construction scien- tifically in various parts of the province, before form- ing an urban - town - rural area network of the cultural facilities with rational layout.

Although the construction of cultural facilities has made great advances in recent years, the development can t meet the increasing needs of the masses of the people.

The situation about the construction of the rural cultural facilities not only reflects the current developmental degree of rural cultural cause,but also influences the future developmental speed of rural economic community and cultural construction.
