Establish the steady-state and transient model using the three hydrodynamics equations (Continuity equation, Momentum equation and Energy equation). By comparing different state equation, it selects the BWRS state equation which is considered the most accurate state equation in current natural gas measurement. It calculates compression factor, density and other Thermal parameters based on BWRS state equation. In Numerical solution of the steady-state and transient model, compression factor, friction coefficient and all the other Thermal parameters are recalculated in each small time step to reduce the numerical calculation error.

Based on the existed research, the study found that the selection of these subjects have rarely been studied, so the selection of this theme has significance in the information society geography theory and can rich the tourist sites in geography study and can guide new thoughts. The second part discusses distance decay effects in web sever when attenuation theory be chose in electronic age location. It considers 7 factors: knowledge spillover environment and yi to technological innovation information reaches nature, decision-maker behavior,human capital factor, supply chain environment, yi to the developed communication net and network of communication lines reaches nature, agglomeration factor, commercial and trade circumstance. Part three studies location significance of outdoor sports websites. Though investigating and analyzing our country 30 cities's outdoor sports websites in China, the author gives out the location characteristics of outdoor sports websites in actual geographical space, and take Shijiazhuang for example, the author analyzes the stadiums gathering effection to the outdoor sports websites which are near the stadiums, and dividing the location into gathering area and non-gathering area the author studies the effects for information flow guiding people flow. Part four is the conclusion which includes four conclusions reached by this article.
