From a new development viewpoint,this paper adopts determined index system and method,taking county level prefecture as basic zone unit,and divides whole China into 3 type regions with fist grade function as protection region,controlling region and development region and 9 type regions with the second grade function.
With the increase of supply gas pressure and film clearance,the supply hole will appear the development region of boundary layer and inertia flow,at meantime boundary layer equation and complete N-S equation were respectively adopted in the analysis of gas flow field. And the mechanism of pressure change was opened out in the inertia flow state by employing stand-off wave and pseudo shock wave.

The analysis of variance, χ~2 test and association indices are used together to analyze quantitatively the interspecific association of main desert species in the outer space of Karamay Agricultural Comprehensive Development Region.
This paper introduced the origin of on items the economic in Tumenjuiang development region, and elaborated the design principals, charicteristics, edition features and the new function of the economic map in this region.
General speaking,among 1980-2003,the developing trend of China agricultural modernization is up forwards,the regional development trends of agricultural modernization is that east is the most high development region,central is the second,west is the third.
So the theory about sustainable development, economic growth, economic development, economic sustainable development, region development and region sustainable development is the base of research on sustainable development of Jilin Province’s economy.
Lower leve of economic development and investment return,finance restriction and slowing reform of economic system,innovation st shortage and higher cost of development region,lower copacity of direct finance in the capital market st restnic western region's capital coming into being.
The aim of study on regional sustainable development is to discover the structure, function, dynamic evolution and interaction of the elements of PRED system, and to approach the strategy and controlling measure to assure sustainable development, Region is the main place to carry out sustainable development.
The Laplace's equation on the region including a dipolar layer and spatial charges was resolved by using the Fourier transform. The dipolar layer is consisted of the latent electrostatic image and toner attracted on it. The spatial charges refer to the toner in the development region. The results of this model is applied to xerography and the field strength of development region was attained.
Incorporated“Enhanced oil recovry prediction model” (EORPM) .dynamic his-tory match is conducted in six development regions including Lanladian, Sartu,Xingshugangoil reservoirs.conseguently,“pseudo oil gas relative pernieability curves”are obtained and ablock is taken as an example, calculation method is illustrated and calculation results area nalvsized.
In this paper, Jiangsu's marine territory is divided into different types of regional development (e. g. , three resources economic development regions). According to the features of the different regional resources, the comprehensive development distribution schemes and specific development projects are recommended.
