fluid region
1.Helium expansion factors in ideal gas region,near critical region,near incompressible region,dense vapor region and compressible fluid region have been computed respectively. The percent errors calculated with ASME Code expansion factor formula for non perfect fluid regions have also been estimated,
3.A mixed lubrication model,based on an unified Reynolds equation in all lubrication regimes including elastohydrodynamic,mixed and boundary lubrication,for prediction of the sliding friction between rough surfaces in point contacts,was developed. In the calculation,the fluid traction in the lubrication region was determined in terms of rheology model for the lubricant,while the friction from asperity contact was calculated by limiting shear stress model of boundary film.
4.By studying the temporal characteristics of crustal deformation,u-nderground hydrochemical parameters,distributions of earthquakes and ratio of P-wave to S-wave before Jingyang earthquake with M_L=5.2,it is found that the crustal deformation,underground fluid and seismicity in this region exhibits different properties in long,medium and short terms before the earthquake.Thus,some anomalies do exist before the earthquake,and the forecast of the earthquake may be made.
6.The new equation can calculate the thermal conductivity and the viscosity of the dense fluid including the vapor and liquid region with high accuracy, based on the calculation of the transport properties of gases at constant pressure, and only need the critical parameters, molecular weight and acentric factor as inputs.
8.THE RELATIONSHIP BETWEEN RETROGRESSIVE FLUID IN THE ARCHEAN HICH-GRADE METAMOR-PHIC REGION AND THE GENEIS OF GOLD DEPOSITS──AS AN EXAMPLE OF GOLD DEPOSIT IN DAQINGSHAN AREA
9.Therefore, the hydrocarbon component ratio of the maximum to the minimum correlativity to replace the main component was used as the abscissa, and the regional indexes of hydrocarbon humidity ratio W_h and hydrocarbon balance ratio B_h as the ordinate individually. On such a basis the dividing chart for carboniferous reservoir fluid properties in K XX well region was established, thus effectively dividing the gas logging characteristics for oil, gas and water.
10.Objective To explore the relationship between concentration of carbamazepine (CBZ) in the extracellular fluid (ECF) of normal brain tissue and the focus region around scar tissue and in plasma in rats. To study whether the extracellular brain concentration of CBZ can be regulated by P-glycoprotein (PGP).
