The resistance value formulas and the relationship between the resistance and pressure......
support pressures which ensured tunnel face stability were presented [3-4]. At the same time, based on limit equilibrium theory, limit support pressure which was adopted to avoid collapse of tunnel...J. Cent. South Univ. (2012) 19: 1883-1891 DOI: 10.1007/s11771-012-1222-z Optimal arrangement for pressure measurement points in working chamber of earth pressure balance shield LIU Chang(刘畅)1......
the true equilibrium concentration of lithium aluminate hydrate under high pressure and elevated temperature. 3.1.5 Effect of alumina concentration Figures 4 and 5 suggest that lithium ion concentration.... In addition, as the equilibrium concentrations of lithium ion during digestion at high pressure significantly differ from that during seed precipitation at atmosphere pressure, a great amount......

Theoretical basis......
as a function of volume were fitted to the MURNAGHAN equation of state [27] to obtain equilibrium bulk properties V0, B0, and its pressure derivatives .  ... modulus and pressure derivative of the bulk properties after full relaxation of the cell shape are listed in Table 1. First we draw our attention to equilibrium volume, which is very important to equation......

The major properties included......
Special nanostructures in Al-Mg alloys subjected to high pressure torsion LIU Man-ping(刘满平)1, 2, Hans J. ROVEN2, LIU Xin-tao(刘新涛)1, Maxim MURASHKIN3, Ruslan Z. VALIEV3, Tamas UNG?R4, Levente... to high pressure torsion. These observations are surprising because deformation twinnings have never been observed in their coarse-grained counterparts under normal conditions. Experimental evidences......
