In recent years, China's sustained, steady and fast economic growth has become a "bright scene" in the world economy. People's living standard has been improved greatly. All these have paved the way for the rapid development of China's petrochemical industry.
The petroleum geology which records the human knowledge on the role of oil and gas distribution,however,had not developed around these two properties but along another way which was in keeping with the process of human cognition.
For the product gasoline,the olefins contents can be reduced to 8%～18% of volume ratio,and the corresponding contents of aromatics increased to 42%～35% of volume ratio. Moreover the road octane number of the product gasoline has no loss.
In view of the necessity of construction of 300kt/a Modified bitumen plant and its feasibility in economy, market investigation and prediction were made on bitumen demand of heavy-duty roads. Financial indexes were calculated and analysis were made on earning ability, uncertainty and risks on the basis of estimation of investment and cost, and the necessity and feasibility in economy of this project were determined.
Along the way, we recover theorems of Steinberg  and E.
Furthermore, the intrinsic definition is just the (now) well-known Crandall-Lions viscosity solution, modified in a natural way to accommodate measurable coefficients.
The main purpose of this paper is to give a procedure to "mollify" the low-pass filters of a large number of Minimally Supported Frequency (MSF) wavelets so that the smoother functions obtained in this way are also low-pass filters for an MRA.

The oscillatory behavior of functions with compactly supported Fourier transform is characterized in a quantified way using various function spaces.
The ecological benefits of different land use types were in the order of green area >amp;gt; public facilities >amp;gt; residential areas >amp;gt; roads and squares >amp;gt; industrial areas >amp;gt; municipal utilities.
Simulation results show that the proposed active suspension system considerably improves both the ride and handling performance of the vehicle and therefore increases the maximum traveling speeds even on rough roads.
We also analyzed a series of ecological factors including altitude, landform, relief, villages and roads which affected the distribution and movement of Asian elephants.
This model problem permits examining a number of properties of the oscillations of the ice cover occurring when hauling freight over ice roads, landing and takeoff of aircraft from ice fields, etc.
