Abstract: X-ray diffraction, infrared, and cation-exchange capacity measurements of the reaction products of montmorillonites with YbCl3·6H2O show that at 1 atm irreversible sorption of Yb3+ increases...
Hydraulic stopple plugging machine is composed of plugging head, connecting box and hydraulic cylinder etc, which is an important equipment for oil and gas pipeline maintenance under pressure. The plu...
It is hard to control the high pressure water in mountain tunnel construction. Distribution of seepage field, stress field and displacement field of tunnel are analyzed by numerical method with equiva...
The key problem of supporting structure design is the load calculation in tunnels with shallow buried depth and unsymmetrical pressure in the situation of weak surrounding rock. The results of simplif...
A pipeline robot is brought forward using the energy of fluid medium transmitting within the pipeline to perform the driving and timing. The robot is soaking in the pipeline full of flowing fluid medi...
The Madsan antimony deposit at the southeastern part of the Niğde province (south-central Turkey) includes a series of epithermal veins hosted by marbles and gneisses. The veins have a simple min...

Abstract A device was constructed in which a clay suspension is hermetically heated at 220°C for a few minutes. This thermal treatment is accompanied by a pressure increase in the cell. Once the valv...
The equation of state and high pressure (>200 GPa) behavior of magnesite were investigated using first principles pseudopotential calculations based upon density functional theory within the general...
A parallel-plate viscometer has been designed for use in an internally heated pressure vesse (IHPV) at pressures up to 350 MPa and at temperatures up to 900 ?C. The viscosity of a melt is determined...
The phase relations at high pressure and high temperature for the FeTiO -MgTiO join were de-termined using several different experimental methods. Through a series of multi-anvil experiments,a phase ...
Our recent paper noted that °∞some of the existing [M?ssbauer] studies (e.g., Fuchs et al. 1995) should be discounted due to th fact that peak widths are less than the theoretical minimum imposed by ...
