The characteristic appearances of MRI were cystic and solid masses,there was fluid-fluid level within tumors in company with bleeding. Tumors were slight low or low signal intensity on T1WI,slight high signal intensity on T2WI.

The signal intensity of the upper parts of the fluid-fluid level was high, and the inferior parts was intermediate. The shape of the SI-T curves were alike, and the SSmax were 16.7% 、 40%、 29.7%、 35% respectively。

The time-dependent forces acting on the plate are determined, together with the dynamic characteristics of the mover and the position of the fluid-fluid interface.

Linear wave interaction at the charged fluid-fluid interface under tangential discontinuity of the velocity field

On the correct writing of the law of conservation of amount of substance at the moving fluid-fluid interface

The reasons for the erroneous writing of the substance conservation law at the moving fluid-fluid interface, which is commonly encountered in related publications, are analyzed.

Extinction theorem was used to deduce the first order scattering cross-section including the double scattering effects for the fluid-fluid rough surface.

It is shown that, under nonequilibrium conditions, the coupling between the process of a stable surface chemical reaction and a hydrodynamic process can induce an onset of convection at the interface between two immiscible Newtonian fluids. A linear analysis on interfacial stability is performed for the fluid-fluid reacting interface of a mone-fluctuating species. The system uniform reference state in space is that of rest. The study is confined to aperiodic regime. For the case where no feedback loop...

It is shown that, under nonequilibrium conditions, the coupling between the process of a stable surface chemical reaction and a hydrodynamic process can induce an onset of convection at the interface between two immiscible Newtonian fluids. A linear analysis on interfacial stability is performed for the fluid-fluid reacting interface of a mone-fluctuating species. The system uniform reference state in space is that of rest. The study is confined to aperiodic regime. For the case where no feedback loop is present in the chemical reaction scheme, unstable mechano-chem-ical regimes are induced possibly by the competition between interfacial chemical and convective processes. The qualitative behavior of the solutions for the dispersion equation is discussed and new conditions for stability are obtained.

The principle and methods for the numerical and analytical solutions of tow-dimension turbulent transport problems; for example, heat transfer of single phase fluid in straight circular pipe arid heat transfer of falling liquid film to smooth solid wall, are briefly introduced. The difference of the turbulent transport phenomena between the fluid-solid interface and fluid-fluid interface, and its influence to the derivation of heat and mass transfer correlations are discussed.Semi-theoretical methods are...

The principle and methods for the numerical and analytical solutions of tow-dimension turbulent transport problems; for example, heat transfer of single phase fluid in straight circular pipe arid heat transfer of falling liquid film to smooth solid wall, are briefly introduced. The difference of the turbulent transport phenomena between the fluid-solid interface and fluid-fluid interface, and its influence to the derivation of heat and mass transfer correlations are discussed.Semi-theoretical methods are introduced for three-dimension turbulent transport processes, such as mixing tank and bubble column. Preliminary heat and mass transfer correlations can be derived from the semi-theoretical analysis, which will be very helpful to obtain the correct transport correlations with less experimental work.Both the theoretical and semi-theoretical analysis can help us to get better understanding of the transport mechanism in the equipment, which may lead us to find out the way to improve the transport process.

Simulation test result shows that, its separating efficiency has nothing to do with the density of oil cut in sewage,as the inlet flow increases its separating efficiency increases; After its geometry shape defined,as inlet psessure increases,the inlet flow increases,The flowfield distribution in the hydraulic cyclone measured by computer simulation are basically coincided with the one measured by laser. Therefore it can be seen as the theory guide fox sample device design. Fluid-fluid hydraulic cyclone...

Simulation test result shows that, its separating efficiency has nothing to do with the density of oil cut in sewage,as the inlet flow increases its separating efficiency increases; After its geometry shape defined,as inlet psessure increases,the inlet flow increases,The flowfield distribution in the hydraulic cyclone measured by computer simulation are basically coincided with the one measured by laser. Therefore it can be seen as the theory guide fox sample device design. Fluid-fluid hydraulic cyclone possesses many strong points, such as, high in efficiency, large in treating amount,light in weight,smaller area in take up,low in maintaining cost and no moving part etc. It especially is suitable for the use of sewage treatment at off shore platform and outlying oilfield.
