The basic thought and design schem of the memory control system to the height of cutting drum of shearer is elaborated,which offers a refrence to the design of automatic control system of shearer.

The factors influencing the wellbore temperature in heavy oil production;

In the light of the energy balance equation of vertical conduit flow and combined with the computational method for the Ramy wellbore temperature distribution,the paper gives the distributions of wellbore pressure and temperature when CO2 is injected at different injection rates,injection temperatures and injection time etc.

Effect of barrel temperature on physicochemical properties and texture of reformed rice;

The effect of barrel temperature, screw rotational speed, screws mixing elements and its assembled configuration on the goodness of mixing have been investigated during the processing of twinscrew extruder.
