pressure tendency
3.the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily; and the spontaneous tendency to become distributed uniformly throughout any container.
4.Through the analysis of the quality and scale of gas field water,it has been determined that the scale of form- ation water in weiyuan gas field belongs in type-CaCO_3.According to the change of system pressure in gas we- ll,the origin of scale,its tendency and possible amount have been estimated in this paper by using Stiff-Davis method and equilibrium data.
7.In this paper a kind of cardio-cerebral arterial bifurcation vessel hemodynamic characteristics are studied with the boundary element method,and the blood flowing velocity vector distributions have been calculated.In addition,the flow field distribution and the pressure on the particle surface are also calculated,when there is flow-round particle at the place of bifurcation,the move tendency of the particle is judged,the possible reasons of causing the atherosclerosis,thrombus,angioma are analysed.
8.Abstract: The processes of thermal-bonding and the features of raw material were breifly described,the temperature, pressure and speed to properties of thermal-bonded fabric were demonstratively related on the basis of three specific trials.Futhermore,the authors present a point of view about the developing tendency of themal-bonding technologies for hygienic market after having an analysis upon current market status.
10.It is proposed to fall the encroachment strength of formation water and abandonment formation on gas reservoir pressure are basic approachs to raise the recovery. Then six methods for raising the recovery of gas reservoir are proposed, being aimed at the factors. The application prospect of these methods and the development tendency of future technique are forecasted also.
