Aim: To study the relationship between changes of learning,memory and orphanin FQ (OFQ) in hippocampus of rats in acute hypobaric hypoxia at two different altitude levels of 4 500 m(moderate) and 7 500 m(serious).

Aim: To study the effect of fetus hypobaric hypoxia on the number and channel character of NMDA receptor of hippocampus neurons.

Structural and functional changes of pharyngeal muscle in rats with altitude hypoxia-induced obstructive sleep apnea syndrome;

The research was the first pilot-scale experiment of low-pressure oxidation (LPO) of municipal sewage sludge.

Oxidation behavior of two-phase Cu-Ni-Fe alloy under low oxygen pressure at 800～900 ℃;

The oxidation behavior of nano-sized Fe-75Cu coatings, prepared by sputtering deposition, was studied at 600 and 800 ℃ under low oxygen pressures, by which only Fe can be oxidized.

When NdBaCuO superconductor samples were zonemelted in low oxygen partial pressure (1%O2+99%Ar), the zonemelting temperature is decreased obviously from that of sample melted in air.

Melting-texture-growth(MTG)progress under low oxygen partial pressure lowered post-treatment temperature of YBaCuO/Ag tapes down to 940℃ which was below 961℃ the melting point of Ag avoiding Ag melting and sticking to furnace.
