Volume rendering is known as the generation of a 2D image directly from 3D volumetric data. Because all the voxels participate in the generation of image, rendering time grows dramatically with the resolution and scale of the dataset. This paper presents a new method to accelerate volume rendering. In order to reduce the rendering time, a technique called ray leaping with back-track is proposed, which is to enhance the acceleration ratio.

According to the behavior that the polymer solution has the characteristics of viscosity and elasticity, the transient flow mathematical model has been established and has been solved by using finite-difference method. The type curves have been plotted. The influence of some properties of polymer solution on the characteristics of the type curve has been analyzed. Compared with the curves simply considering polymer solution as power-law fluid, it is shown that the pressure derivative curve considering the elasticity upwards less at the radial flow regime. Therefore, it's necessary to consider the elasticity in dynamic analysis on pressure of polymer solution.

In many applications, streamline simulation shows particular advantages over finite-difference simulation. By the advantages of streamline simulation such as its ability to display paths of fluid flow and acceleration factor in simulation, the description of flooding process gets more visibility. The communication between wells and flooding area is represented appropriately. In low permeability reservoirs fracturing has been applied to stimulate. But some of the well patterns are not appropriate to fracture. Through streamline simulation this paper presents that inverted nine spot flooding pattern does not suit the naturally fractured reservoir. In this study authors show that some artificial fractures even reduce the sweep efficiency. And a practical relationship between the well and row distance and the degree of anisotropy is given. This method has been applied to the S382 reservoir in Daqing Oilfield. The production history of this reservoir is about 11 years. The reservoir is maintained above bubble point so the simulation meets the slight compressibility assumption. New well are placed follow this relationship.

This paper takes knowledge points as key factor in all type of learning process, and any E-learning activity should regard knowledge points as kernel concepts for organizing and extending learning resources. Therefore we suggest the construction of subject knowledge base in E-learning, and provide a universal model to build subject knowledge networks. Besides the purpose to aid E-learning process, subject knowledge base can also be used to realize simple learning navigation by referring to relations of knowledge points, and in this way personalization of learning is possible. In addition, this paper defined a new type of E-learning teaching resource library that internally contains Scorm standards, but externally exhibits semantic structures while distributed as a whole on the Internet.

Electronic commerce can provide fast and convenient transactions, but in the mean time the phenomenon of absence of credit occurred frequently because of e-commerce's virtual and indirect features and also the lack of efficient Integrity Mechanism. This has seriously hindered the development of electronic commerce and will even threaten its survival. Therefore, the construction of credit must be paid great attention to during the process of the electronic commerce development. This paper mainly described the following aspects: the current situation of China's e-commerce Integrity Mechanism, the role of the credit in the e-commerce, the presents of the Non-credit, the influence of integrity and absence of integrity to the development and the construction of Integrity Mechanism.
