Research status quo and development trends of coal flash hydropyrolysis;

Using XPS analyses the organic sulfur of seven different Chinese coals and their semi-cokes from flash hydropyrolysis were studied.

For a kind of low carbon micro-alloyed steel,a thermal simulation test was conducted with samples of F+B+P microstructure and the effects of its cold deformation at room temperature on the distribution,size and composition of precipitates were investigated via a technological process for rapid heating and short holding time.

During the rapid heating for limestone calcination,a new platinum-membrane reactor(PMR),which accurately weighs the sample and acquires temperature of particles,was used.

Based on studying the phase diagram of the Ti-Al binary system, the microstructure types and continuous cooling transformations of the TiAl-based alloys, and the heat treatment practices and effects, a new rapid heating cyclic heat treatment technology with the characteristics of rapid heating, holding in single α phase region, short holding time and relatively slow cooling was proposed.

Microstructure of TNT deformed under fast loading was observed with optical microscope and SEM.

Based on the analysis on air charging process with theories of variable-mass system thermodynamics and gas kinetics,a mathematic model of the pneumatic system that composed of quick recharge station and cans on the air powered vehicles was built up.

Application and studying of rapid loading method on dealing with the quality matter of affusing pile;
